Hi everyone. I have been posting here and there about my recent re-discovery and acquisition of a car that I have known since I was 15 years old. In 1987 my father bought his fourth Porsche. A 914-6 born in 1970. It was a bone stock car in white over black that had been driven a little under 100k miles. It was well taken care of and had no rust. After driving his yellow 73 2.0 on the track and in PCA racing he wanted to retire that largely stock car to the street and get a dedicated racer.

The 6 was immediately sent to a body shop to get a chasis stiffening and flare treatment. An IMSA airdam was installed along with a rear spoiler. He took the BBS 7s and 8s off his 944 Turbo and shod them with cantilever slicks from hoosier. He then found a 2.8 RSR Bosch mechanical FI high butterlfly stack monster engine from PAR porsche in NY to motivate the car. Redline was set somewhere north of 9k rpm. Here is a pic of the original build:



He drove the car in many events for around 20 years. During that time i bought his old yellow car and i turned that into a race car as well. We even drove together (in different groups when i had the yellow car) at some events. We would also share the racing duties with the 6. In 2008 he sold the car and moved on to other cars but this one has always held a special place for me.

Two years ago I ended up meeting up with John who had bought the car from my dad. He was great and generously asked if i would like to join him racing for the year as co-driver. I jumped at the chance and we got (and get) along really well. At the end of the season he offered the car to me and, after selling the silver 75, was able to make the plunge.

The emotional bond and connection to my dad who passed in 2018 that this object evokes is strong and in some ways unexpected.

With this thread i hope to honor that tie to my dad by sharing maintenance, improvements, and continued racing with this special (to me) car. And I hope my dad can see it all.

Great story and I am so glad you got that very special car back in your garage. I know your dad is smiling as he looks down to see you enjoying his car.

Posted by: 76-914 Mar 11 2022, 09:04 AM

Great story and nice looking car.

Posted by: BillJ Mar 11 2022, 09:13 AM

Once i purchased the car the first order of business was to go through all the critical systems and to address general condition of the car. There was a lot of cleaning to do throughout and as each area was cleaned the plan was to paint and update whatever was needed.

I started with the brakes. At Summit Point PCA race they were overheating so wanted to do a full analysis of needs there.


This is what they looked like in the front:



I decided that all 4 calipers should go to PMB for full restoration and i ordered new soft and hard lines at each corner. Also, the cool brake ducting was in terrible shape and certainly not helping the cooling (and maybe i should brake less too).

Restored and installed:

Also notice the stainless steel line - that is another story i will cover later.

I also replaced the brake fluid reservoir, lines, and master cylinder.

Next i addressed the interior. The seats were very out of date having been in there since 2003! The belts were out of date as well so those needed updating. Once the seats went in the mouting in existing brackets worked well on the width but they did sit higher in regards to the shoulder belts. This meant an almost 45 degree angle upward to reach the openings from the wirewall mounts. This absolutely had to change so i had a new bar made up and a friend of mine installed behind the seats at the correct angle. Safety first!

Here is the bar with seat and harness installed. You can see the old mounting points in gold still in place as well.



And the harness and seat setup.

Next was installation of fire suppresion. The car had a single hand held extinguisher in between the seats. Meets race rules but not really adequate for a serious fire of any sort. Chose aqueous foam as it is proven and doesnt cut off my oxygen like a gas solution. There are two nozzles pointed at the carbs in the engine bay, two nozzles pointed at the floor/occupants in the cabin, one where the original gas tank was that now houses battery and fuel pump, and one in front section of front trunk that addresses the fuel cell. I also have a hand held Element extinguisher for minor issues that wont leave a huge mess like the foam will.

Posted by: BillJ Mar 11 2022, 12:10 PM

Next item to change was out of necesity. On the way back from the pro shop a wire ended up contacting something bad under the dash and i had a ton of smoke in the cabin. Pulled over and grabbed the extinguisher thinking the worst. I hit the kill switch and no active fire started thank goodness. Of course i had high confidence in my suppression tools but glad i didnt need to use them!

So the decision for what to do for the electical system? Choice A was to patch the melty wires and keep rolling. Choice B was to install brand new -6 harness. Choice C was to install aftermarket harness kit. Choice D was to go with an AIM PDM, dash, and smartycam setup.

Choice A was pretty hack and i really didnt want to have things done part way. B was very attractive but at a price point of $3600 gave me some pause. Option C i actually acted on and purchased a harness by Bare Bonz from JEGS. However I ended up going with solution D as, for around the price of just the original style harness, i could get a full plug and play setup for the track that was custom built for my needs. I need only a small fraction of wires and kept headlights, wipers, brake lights.

Major components are the Power Distribution module that serves as fuse block and central brain of the system, the Dash which is really configurable, and the smartycam which autorecords when you go faster than 25mph.

In concert with the electrical system i wanted to address the dash.

The PO built a nice dash but it was rather heavy and not really in keeping with my vision so worked with an awesome friend of mine who took a stock dash and rebuilt the front out of aluminum for a clean look that will allow installation of accessories. I am really excited about it but still need to figure out a nice enclosure for the back of the gauge pod. The hoop and upper secrion of dash are stock so will try to mirror as close to original look as possible. Function trumps that though. Will be installing electrical kill switch in next couple days. Has the AIM keypad, fire extinguisher pull, and data upllink installed.

Posted by: BillJ Mar 11 2022, 12:42 PM

The cage had a bar under the dash that was meant to keep integrity in case of side impact. However for me the bar landed about an inch away from my knee in my preferred seating arrangement. If i had any impact to the front i would likely impact my kneecaps in the steel and probably be permanently injured. Not so cool!

So had a bar made to fit higher up under the dash that provides the same protection without the same clear risk. My buddy Ryan again to the rescue!

Posted by: Dion Mar 11 2022, 03:35 PM

Bill that’s a fantastic back story. Glad the 914
came back to you. Good luck with the rejuvenation. Looks like you have it well in hand.
Would love to see any pics of the RSR power plant in that chassis.
So cool.

Posted by: BillJ Mar 12 2022, 10:40 AM

Next for safety was the window net. The old one had a bar bottom and top mounted to the cage through loops welded in. The spring loaded bar was from the bottom meaning that the net flipped up. This is not a safe nor legal to current rules design (my dad set it up this way originally) so it needed to go. Current net attaches directly to cage nascar bars on the bottom via 4 straps. The top uses the original cage mounted loops and has the spring mounted bar. Net drops down quickly and easily.

This pic i used already but shows the setup.

The pedal cluster, to my knowledge, had never been refreshed and it looked it. So i sent mine to Bruce Stone who did an awesome job. Here it is installed but prior to wiring cleanup:



The original pedal board did not exist so i purchased and installed a rennline board, dead pedal, floorboard, and all three pedal grips.
Here it is today while i wait for the engine rebuild (more on that later)

Posted by: BillJ Mar 13 2022, 05:58 PM

Exterior and interior needed a significant cleaning and i also wanted to rebrand the car a little more to my liking. My inspirations included the factory GTs and some privateers. I am also a little bit of a watch guy and really like the Heuer livery so focused on that. I am earnestly looking for a reasonably priced set of Heuer rally timers but they are soooo expensive so am holding off on that for more important things.

After deep cleaning, clay bar, and two stage polish with the orbital the car was ready to rebrand. Here is where the car is as of today:

A lesson learned.

In february i went to Roebling Road to race with VDCA. Just prior to first practice we noticed some fuel leaking from the engine bay. Turns out a hose had failed and we quickly sourced a new one and replaced the entire hose that was faulty. However, this gobbled up the time that was to install the pedal board and integrated pedal stop. The car previously had a bolt installed below the pedal to serve as a stop as it had no board. I re-used that hole to run the brake pressure sensor for the AIM PDM. Thus no stop for the throttle anymore.

Lap 2 of practice coming onto the front straight the pedal moved further than it should and bent the throttle control arm and locked the throttle open. I moved off track to the right but shifted. Engine saw 9022 rpm before i shut it down. Result we would find was some bent valves only. Not terrible but certainly ended the weekend.

Lesson learned? Always always always check your equipment and never go out without knowing you are 100% prepped. Not realizing i had inadvertently removed a safeguard and then not installing the replacement when it is right there is not acceptable.

Posted by: bkrantz Mar 13 2022, 08:47 PM

Just curious--what's the max size driver that can fit with those seats, and the cross bar behind the seats?

Posted by: BillJ Mar 13 2022, 09:46 PM

Not sure on max but i am 6' and have about 1" extra room on the rules with my helmet on. That is without removing the bottom seat cushion.

Posted by: BillJ Mar 15 2022, 07:52 AM

So since the engine needs to be rebuilt it is a good time to address the engine bay. The entire thing had a layer of grease/dirt/grime covering black paint covering the original white paint. I started out by simply trying to degrease but it was clear that it was wholly inadequate. Thus began the painstaking process of stripper and scraper.



This took on and off around a week to get to a point i felt comfortable to paint.

Posted by: BillJ Mar 15 2022, 07:59 AM

I did a self-etching primer followed by semi gloss paint. As i redo the interior areas i am using this in anticipation of a few years from now redoing the body. Have already cleaned and painted the cage and cabin, trunk, and now engine bay. Goal is to look for rust and provide a clean surface to work on mechanicals.

Also installed new engine bay seals as old ones were quite aged qith cracks and tears. Love that top and bottom in this area are clean!

Bill, looking great! What size engine are you putting in?

Posted by: BillJ Mar 21 2022, 06:35 PM

2.4 twin plug short stroke. Super excited to have a motor that will be in a class and be competitive! Too bad the driver is sooooooo slow.

Posted by: troth Mar 21 2022, 08:03 PM

What dizzy are you running?

That engine sounds like fun. What bore are you running to get 2.4 SS? I’m going to be tearing down the core engine I have soon to see what we have. The previous owner claimed 2.5L but couldn’t confirm what crank or bore.

Posted by: BillJ Mar 21 2022, 08:28 PM

I am running a new JB Racing dizzy. The original marelli ones are priced crazy high so this was a great solution. New parts readily available and built to spec.

Not sure on bore exactly but i know the crank is 66mm. Told him i wanted to be competitive and legal but not build a 10 hour motor either.

Posted by: BillJ Mar 24 2022, 02:54 PM

Big setback yesterday. Was planning on running with PCA at VIR this weekend but motor wasnt ready. Had it running and in the car but not tuned yet when an oil return tube started leaking badly. Not enough time to repair and retest at this point. Also have a broken tip for the accelerator cable guide tube on the firewall in engine bay which is preventing the cable from being installed.

Pretty depressed today as there has been a ton of work to date and this was an event i was very excited about.

Posted by: DRPHIL914 Mar 24 2022, 08:31 PM

wow you’ve really been busy getting it ready. sorry to hear that you can’t go this weekend. i hope to see this in person, let me know if you will run here at Roebling road or i around Charlotte in the near future!

Posted by: BillJ May 4 2022, 09:06 PM

Well a mixed bag but mostly good today. Started off the day learning that i could not get to the dyno before the event. Not a huge deal as it had tune time on engine stand rig and in the car a bit but would have preferred to do more diagnostics.

Then was doing a gravity bleed on the brakes and dropped the bleed bottle all over the fender, myself, and the floor. Super not fun that!!!

However had some pluses too. Got a really hard brake pedal after a friend came over to help. I could not get one from pressure nor gravity bleeding and was giving me fits. Very happy with that.

Lastly I put the "Dunpy" stickers that our very own #40 hero reproduced. Not placed where the factory car had them but i like the location i picked. @Maltese Falcon

With the GT lid installed and the air cleaners in place I am essentially ready for next weeks Jefferson 500 races at Summit Point.

@http://www.914world.com/bbs2/index.php?showuser=11106 - John in Denver did my engine. Had the heads done at extreme Heads in Florida (they provide heads to Singer for their engines) and the twin plug distributor from JB Racing also in Florida. AA for Ps and Cs and the 66mm crank was from Johns personal stash. Reused the PMO 46s that were already there as welll as the case. Did get a new shroud made as my old one was pretty beat. New coils and msd digital boxes.

Work is progressing consistently. New rear decklid with period correct latches and have the gt drilled style hinges from Oscar to install on both ends. Had a new fuel cell and mount put in along with new shroud and cooler from Patrick motorsports installed. Lines for oil and fuel need to be reinstalled..
doing new oil lines. Engine case is getting boat tailed while we wait on internals. Thinking custom Mahle for ps and.cs, carillo rods, pauter rockers and pushrods, etc. I want this engine to be perfect.

Car is looking good Bill ! Your engine builder also builds awesome shipping crates. One of his very "Special" deliveries was a race trans brought to a small California airport in his Cessna, close to the track. It was for a client that broke his 915 box on Saturday...but finished the race weekend with a fresh gearbox !

So a component that was really not that great was my quick release. It is the style that has two pulls on either side that allowed you to remove the wheel. At times it would bind and not easily release. Never had to escape the car but if that part doesn't release quickly when i really need it to then that is a safety issue. So i asked here and did some research and found i liked the design and operation of the rennline version. Only two downsides. 1. I cant use the porsche crest horn button unless i use what, to me, is an ugly retaining ring. So i may try and find a sticker to put there or leave as is. Not a biggie really.



Second issue is the now much longer assembly putting the steering wheel maybe an inch or more closer than i want. Does anyone know if a short hub adapter exists for the 914-6/911 steering shaft? Current one (it is the black accordian hub in the second picture) is 3" deep. Do they make.one that is shorter than that? 1" would be ideal. Current one is the collapsible version which i dont need with six point harness and race seats.

Posted by: infraredcalvin Feb 9 2023, 09:43 PM

Your car is looking great, I’m almost jealous (don’t say that out loud near my car). I’ve been dreaming of an rs+ spec 2.7 for years, already have the 7r core.

I look forward to your impressions of your new engine on track, are you going under 2.5L?

Yes building a legal 2.4 on the off chance they check. It is pricier to do that way because it requires custom Ps and Cs. Having LN do those. Also having Extreme do the heads. Hope it will work out well.

The car did previously have a 2.7rs-ish motor. The issue with that is of course it is in the same class as the 3ltr RSRs which it just cannot compete with (at least with me driving) and its too big to run in the up to 2.5 class. According to a couple of the groups i run with one cannot build larger than 2399cc. There are quite a few cars in the under 2.5 ltr class as well and looking forward to compete and have fun.

So the case i sourced out of AASE had already had all the work completed (aside from boattailing which the builder has done) and did NOT include shuffle pinning. There are differing opinions out there but many say on the magnesium cases that you should not pin due to higher risk of cracks developing. Aluminum cases from what i heard should be.

Posted by: BillJ Mar 26 2023, 07:23 PM

New upgrade will be this comms system for racing. May certainly come in handy especially for longer runs and for knowing when that green flag is flying! Helmet is already wired and has correct plug, mic, and speakers so all i have to do is install in the car.

Happy and honored to be part of this build. I am about to wrap up the 6 case build. This build was started with a barren 6 case (used, not NOS), and after a long discussion Bill decided what gears he wanted to go into it; A, GA, O, V, Z. We used data on my site to see what was bolted to similar engine configurations, and what goal was at what RPM. Today is final assembly and then ship it out.

Step 1, the case and cleaning with the laser.

Posted by: Dr Evil May 17 2023, 07:38 AM

Next, now that the mag alloy is bare, time to put protectant on it to prevent future oxidation. I like Gibbs. Easy to use, lasts a long time.

Posted by: Dr Evil May 17 2023, 07:43 AM

Next, onto the usual work of setting everything up correctly. Since this was a barren case, I had no start point as I couldnt use the pinion, or diff that came with it so I had to get close and then adjust from there. It didnt take but two adjustments for the pinion and one for the diff to get preload, back last, pinion depth all set perfect.

the N number on the head of this pinion was 10, and I just happened to hit that mark dead on. Tolerance is +/-0.03mm.


Using prussian blue I check the contact pattern of the ring and pinion. I do this with all builds because rarely, but not never, you can set everything perfectly to spec and it will not have the right contact pattern. The newest of these is 47yo or so, there will always be some wear. It calms me to take this extra step.

On to the gear selection and assembly. Chosen from my stock were A, GA, O, V, Z. New teeth, sliders, bands affixed, everything assembled and forks adjusted.

Posted by: DRPHIL914 May 17 2023, 08:53 AM

very nice! Curious what the stock 914/6 gears were vs what was selected, what was the goal, is it racing?

Posted by: BillJ May 17 2023, 11:17 AM

Hey Phil. Yes race only. Stock gearsets and ratios for a standard 6 box are A 3.091, GA 1.778, O 1.217, V 0.9259, and ZA 0.7586.

So essentially i am only changing the last gear from ZA to Z 0.7931. Doesnt seem like a lot but that ZA gear is way too long and the rpm drop too great to be effective coming out of a faster corner like last corner at Road Atlanta for example. The gear selection keeps me in the anticiapted power band for every gear.

My former box has M, S, X as final gears and i would run out of rpm on the straight at most tracks i run. Was very frustrating to watch other cars creep away as i had to hold at 125mph basically. No fun.

Last before its packed and shipped.

Selected a tail cone from a donor, dirty but not corroded. Had concretions and all manner of crap contaminating it. The laser, preceded buy a little elbow grease, made short work of it.

Scrape of the chuncks.


First pass patch with the laser to assess wattage and duration was appropriate.


After I let'er rip.


After Gibbs treatment and installed.

Things are starting to come together. Engine will be at the shop on Tuesday. Transmission arrived yesterday. And today they started the install for the oill lines. I have taken the decision to replace essentailly all the lines and a new cooler up front. The oil tank was professionally cleaned as well. Also adding a thermostat and second oil filter. Not leaving anything to chance.

A couple shots of the install so far

Posted by: BillJ Jun 26 2023, 09:55 AM

Two step process for me. Wiring was all hinky and fried so went with the AIM PDM08 system. Essentially manages everything with solid state fusing. Very customizable and fairly easy to setup. It includes the power distribution module, gps beacon, and the aim dash as well. Hooked up a smartycam which automatically starts when driving. You do need to wire the harness or it can be done for you. I worked with Matt Romanowski and he made it relatively painless.

Yeah it is not cheap. Think it was around $3k when all was said and done. However with all 100% new wiring and lots of flexibility was worth it. Get the 32 not the 8 like i did. Prices seem to have went down a little so should net out

Posted by: BillJ Feb 6 2024, 01:40 PM

Have not updated this in quite some time. Had gotten the car back and did some dyno time to get initial breakin started. Not overly interested in looking at hp/tq numbers but just make sure it was set to initial tune. Car sounded good and was excited to get it to the track for continued breakin laps and had 1.5 days to do that set on Summit Point with PCA.

Some pics from Sept last year.

Got to the track and ran for a few laps before encountering some stuttering. Shut the car down and rolled in. Glad i did that it would turn out.

A lesson learned is that after any intiial break in you must retorque everything. Turns out that during breakin there were a couple studs that pulled out and one of the head stud nuts loosened up. After Peter Dawes was kind of enough to loan some of his guys for some diagnostics they found these issues. Net result was no apparent damage thanks to shutting down quickly and there was confirmed zero damage upon imspection after disassembly once i took the car back to my builder. He is finishing the case work and putting it all back together i hope by end of this month. We made a change in the head studs to a more appropriate type and oversize inserts to ensure we dont have another issue. We want it right.

Long journey. Patience rules.

In the meantime i bought a 2020 911 to manage my speed urges.

Now that I have the car back from engine build going to do some fine tuning and updates. First off is getting for primary wheels a more appropriate combo. The wheels used on some of the GTs used fuchs in the front of 15x7 or 8, but fuchs were not made in 15x9 widths yet to get more meat on the powered end. So they used minilites in the rear instead. Some of the 911s also used this setup. I wanted to take a nod to this heritage and sprung for a nice set of Al Reed wheels done in rsr-style finish in the front and a pair of minilites I bought from Steve Limbert about 2 years ago but hadn't mounted yet. Tight fight but looks like they will work without rubbing. Love the style and the historic homage. Some won't understand but if ya know, ya know.

So on to more updates now!

As a track car I want to have the ability to communicate back to the crew and to get information from them as well. As I had mentioned before, I bought a radio set to make just that happen. First step is to plan out wiring and radio box in the car. After that will update with the external antenna install
Here is how wiring is roughly routed as of today. Any suggestions are welcome!

Steering wheel push to talk



Down steering column



Down cage to floorboard



Over to radio box. Antenna and helmet plug (my roux helmet has a jack and speakers/mic built in) off of radio as well

Posted by: infraredcalvin Jun 6 2024, 11:54 PM

Get one of these wheels, I don’t have them hooked up, but i was going to do one to turn on my datalogger…

Posted by: BillJ Jun 7 2024, 10:50 AM

I like your wheel for sure, but paid a small fortune for the porsche wheel so I am staying put lol. The AIM system I have logs everything automatically and starts the camera at 25mph to boot.

The only thing I am worried about is the cord at the steering wheel. How have others mounted to stay free and clear of binding?

Posted by: BillJ Jun 17 2024, 04:34 PM

Soooooo.... after patiently waiting and updating had an amazing father's day weekend with the car. Spent Saturday breaking in the engine and shaking out the race radios, new wheels, and other odds and ends. Engine was okay but lots of hesitation between 4100 and 4900. Kept going moderate pace and different rims. Sunday proved to see that lag spot go away as we played with jetting and kept a close eye on plugs and boroscoping the cylinders to see if everything looked OK. The car performed quite well as I gradually dropped a couple seconds off lap times every session. Ended up being fairly fast even passing a gt3. Not shabby.

Lots of compliments on how the engine sounds and how the car looked on track. Really.satisfying and spent great time with my son and my buddy flew in to help with all the technical stuff. He was awesome as always.

In preparation for suspension update and looking for rust, I had the car dry ice cleaned and rock guard coated for the entire underside and wheel wells. 54 years of road and track grime gets into every crevice. Pulled the floors down to essentially bare metal and relieved any loose coating from everywhere else. Found some rust in rear pan that will be replaced after the rest of the race season. Have every metal piece I may need ready to go. An assessment by a great shop early this year indicated after probing as much as possible that was likely limited to just floor but will see when we get in there. This car has lived in garage or trailer for at least 40 years so hopefully limited degradation.

I am very happy with the result!

Loves F1 and has everything from a 911, to old school suburban with hot rod customization, to Bonneville salt flat cars.

Haven't posted in a while! Father's day had a great weekend and the car ran well. However I did have another head stud pull out and thus yet another rebuild. I had the case fixed but decided to pull the trigger on a brand new case from Porsche. Not 50 year old magnesium but brand new zero heat cycles no excuses case. I did check on getting billet done but they just don't make the 7r case. Only damage to internals was the slightest of nearly imperceptible blemishes on the nikasil cylinders so.sent those out to be redone.

Engine is progressing now at Black Forest racing (Cody). Here are shots of the case, which other than the other one I have, is the last one in the country at present.
