Hi guys

I sold my previous track car and decided to buy a 914.

Key features that sold me on the 914
-old
-light
-rwd
-mid engine

My previous track car was a riot and difficult to class in different organizations. I bought the 914 because it will be easier to class due to the "simplicity" of the build. This will be primarily a track car however it will be street legal with creature comforts.


I am located in WNY, so old classics are scarce and the ones that did survive are on the verge in splitting in half or fully restored. Since I am an older college student, finding one in decent shape will be hard.

I found this guy in California and had it shipped to me.

While the pics looked great, I totally overpaid and it was a rusty bucket with a maco paint job. I bought this from Beverly hills car club and sales guy told me there was no rust and it was a solid car. What a load of of bs... It was also my fault for being naïve and putting faith in humanity. Next time ill go 3rd party and look at it person. Lesson learned. Moving on...

First order of business was to replace all the rust and fab a roll bar.

Sorry to hear about the bad sales experience. That said, looks like that didn't hold you back from moving on!

What did it start as? Looks like a '74 (well maybe 73.5 in back based on number of bumperettes (IMG:style_emoticons/default/wink.gif) )

What are some goals of the build? Making it meet a particular group/class/sanctioning body? Keeping a 4 or making into a 6?

Engine Bay reinforced with 16 gauge.

Frunk?
Well thats toast too. I ended hacking that area and fabbed a front section and dimensions according to the book

Before
(IMG:http://www.914world.com/bbs2/uploads_offsite/i.imgur.com-23854-1604569978.2.jpg)

After I am reusing my old Radium Fuel Cell that contains a FIA bladder and an intern surge tank. I never experienced fuel starvation with setup. I use two walbro 255 lph pumps (redundancy) and a continuous lift pump.

(IMG:http://www.914world.com/bbs2/uploads_offsite/i.imgur.com-23854-1604569979.6.jpg)



I got creative and 3d printed some dimple dies!


(IMG:http://www.914world.com/bbs2/uploads_offsite/i.imgur.com-23854-1604569979.7.jpg)


testing...
(IMG:http://www.914world.com/bbs2/uploads_offsite/i.imgur.com-23854-1604569979.8.jpg)

It verkssss

If anyone is interested Id be happy sell some Dimple dies, They can be used on a press or impact gun.

(IMG:http://www.914world.com/bbs2/uploads_offsite/i.imgur.com-23854-1604569979.9.jpg)






I am using a cheap defroster from jeggs. I 3d printed my vents with a high HDT material so they wont melt.

(IMG:http://www.914world.com/bbs2/uploads_offsite/i.imgur.com-23854-1604569979.10.jpg)

I also added curved vanes to spread the flow

(IMG:http://www.914world.com/bbs2/uploads_offsite/i.imgur.com-23854-1604569980.11.jpg)



Easiest engine pull of my life.. Bye bye..

(IMG:http://www.914world.com/bbs2/uploads_offsite/i.imgur.com-23854-1604569980.12.jpg)



Here is where I might lose some followers. *ahem* I am still a college student working full time so I need a cheap powerful engine. Cheap and powerful may not belong in the same sentence but I just got to make due..

Hello K24

(IMG:http://www.914world.com/bbs2/uploads_offsite/i.imgur.com-23854-1604569980.13.jpg)

*flame suite on*

Why K24?
-Efi
-Parts everywhere
-Stock HP is low however with mods its known to achieve 240whp with decent torque
-500 hundred dollars on ebay..
-Track reliability (if not right) Meaning proper oil baffling and correct timing. Its very easy to screw up timing.

This will be controlled with a standalone ECU AEM Infinity from my previous car that I parted out.

I started to prep the engine, pulling crap I don't need.

Parts that I used for the swap

- S2000 intake manifold (in retrospect I should of used a RSX type-s intake manifold due its simplicity and correct orientation but to late now)

-S2000 JSP fab intake manifold adapter

-Track tuff coolant adapter

- Rsx Type-s oil pan with two oil baffles to prevent oil starvation

- 80mm throttle body ebay special, to my surprise its quality

- Cheap ebay water coolant adapter that mounts to the head

- I went with Fuel Injector Clinic injectors that are 1000cc (why so large? I may go turbo later, also on the track I will be using e85 for cooler temps)

- KEP adapter to 986 trans 5 speed ( I chose the trans that was closest geared towards the k24 and its cheap)

I inspected the engine and everything looked clean.

That the secondary baffle that prevents oil sloshing up the timing chain cover.

(IMG:http://www.914world.com/bbs2/uploads_offsite/i.imgur.com-23854-1604569980.14.jpg)

(IMG:http://www.914world.com/bbs2/uploads_offsite/i.imgur.com-23854-1604569980.15.jpg)

Old IAT sensor location. Bad Idea since it gets heat soaked. So I 3d printed a solution.

(IMG:http://www.914world.com/bbs2/uploads_offsite/i.imgur.com-23854-1604569980.16.jpg)

Don't worry I am using high temp material CF-PC

(IMG:http://www.914world.com/bbs2/uploads_offsite/i.imgur.com-23854-1604569980.17.jpg)

KEP Adapter

(IMG:http://www.914world.com/bbs2/uploads_offsite/i.imgur.com-23854-1604569981.18.jpg)

It fits it ships

(IMG:http://www.914world.com/bbs2/uploads_offsite/i.imgur.com-23854-1604569981.19.jpg)


Looks like it will fit

(IMG:http://www.914world.com/bbs2/uploads_offsite/i.imgur.com-23854-1604569981.20.jpg)


And its in

(IMG:http://www.914world.com/bbs2/uploads_offsite/i.imgur.com-23854-1604569981.21.jpg)

(IMG:http://www.914world.com/bbs2/uploads_offsite/i.imgur.com-23854-1604569981.22.jpg)

(IMG:http://www.914world.com/bbs2/uploads_offsite/i.imgur.com-23854-1604569981.23.jpg)


I started to Fab the coolant pipes. I am not an expert in tig welding aluminum.

(IMG:http://www.914world.com/bbs2/uploads_offsite/i.imgur.com-23854-1604569981.24.jpg)

I didnt want to route the coolant lines underneath since the car is going to be low. Best solution is through the cabin.

(IMG:http://www.914world.com/bbs2/uploads_offsite/i.imgur.com-23854-1604569981.25.jpg)

I 3d printed mounts that I made that holds coolant lines and fuel lines on top. Its a modular system that I came up with.

(IMG:http://www.914world.com/bbs2/uploads_offsite/i.imgur.com-23854-1604569981.26.png)

I also 3dprinted a shift knob since Porsche knobs are so expensive... I mean its just a knob....


(IMG:http://www.914world.com/bbs2/uploads_offsite/i.imgur.com-23854-1604569982.27.jpg)


I disliked the turn signals and mine were junk.

here's my solution

Turn Signal buckets with two day light running lights and one turn signal led. If there is interest for this I would be happy to 3d print some for the masses.

(IMG:http://www.914world.com/bbs2/uploads_offsite/i.imgur.com-23854-1604569982.28.jpg)

(IMG:http://www.914world.com/bbs2/uploads_offsite/i.imgur.com-23854-1604569982.29.jpg)


This is quiet a lengthy post Ill update later.

Well you live an learn. Majority is my fault could of been avoided.

Its a 74

Strictly a streetable time trial build. I've been tracking with NASAMA for 4 years but recently moved to WNY. So I plan on doing a mixture of NASA NE MA TT events. I am planning on TT4. I think the car can do a 2:07 at watkins on 100tw tires.I am also looking into SCCA events near me. For fun track days I usually do anything on motorsports reg. I am planning on being a nasa instructor too.

Ditching the flat 4 for a K24. Would love to do a EFI 6 but that's just way above my budget.

Thanks!
I got the car in February, I was hoping to be done this month but school got in the way.

Does anyone have any recommendations on optimal track ride height?

Great work. Curious if the Le Man 914 required all these structural enhancements? I guess if your changing engines to a non VW/Porsche setup, it's necessary.

It depends on a few factors. If you're relocating suspension pickup points, I like LOW for a track only car. I run mine 2 - 2.5" ground clearance in the front and about 3.5" in rear to give a little rake. That would put the suspension outside its normal range of motion unless you raise the front strut spindles. Also ideally raise the rear trailing arm mounts. You have to run pretty stiff springs to run that low too. I'm at 500 front and 350 rear currently and am seeing some minor scraping on the front splitter, so may up the rates a little more.

I'm pretty extreme though. Most people run higher ride height.

The mating process was actually pretty simple

986 2.7L 5 Speed trans
KEP adapter plate w/ KEP flywheel uses the stock k24 starter
OEM 986 clutch sachs
The mounts I made my self.
I used Renegade for the stubs and CVs

Here is the model I designed. I made this work my purposes but it can easily edited to relocate one led to the top so that way the oem lenses diffuses the light. This is also made to work with oem gasket. It secures itself with the same bolt with a washer and nut on the back.

The two angled platforms are for the daytime running leds. I can do with one single led or none.

Wow.
Impressive.
Look forward to seeing it all together.
The K24 is a solid power plant. Good choice. Much more innovative than the typical Sub swap.

K24, cool (the details totally got lost in the midst of those HUGE photos, I blew right past all that...you should resize and replace those pics.)

We're getting 295whp with the K24 in our Super Touring car ('08 Civic Si), all motor. What's the details on your build? We're using a sequential Quaife gearbox but it's the transverse-mounted FWD version so wont work in yours (unless you're transverse-mounting?) It's a total hoot to drive... - Greg

Suspension and Brakes


FRONT
While this thing will be light. I need pretty good brakes. I decided to reuse my big brake kit from my previous 2002 and retro fit the stoptech bbk to the porsche 911 strut. I will be also using MK60 4-way ABS with Motorsport programming.

The caliper is a c43 Stoptech unit that doesn't use any seals and its cnc'd. Weighs 4.2 pounds and one bolt pad changes. The rotor size 309mm x 32mm.

OEM S2000 Top Hat
(IMG:http://www.914world.com/bbs2/uploads_offsite/i.imgur.com-23854-1604589803.1.jpg)


I started by modifying the top hats to fit the 911 mounting holes.

(IMG:http://www.914world.com/bbs2/uploads_offsite/i.imgur.com-23854-1604589803.2.jpg)

Building the adapter

(IMG:http://www.914world.com/bbs2/uploads_offsite/i.imgur.com-23854-1604589804.6.jpg)

Took me 3 different versions to 3d print before I sent my file to get cnc'd

(IMG:http://www.914world.com/bbs2/uploads_offsite/i.imgur.com-23854-1604589804.12.jpg)

Fin

REAR
The rear will be using PFC 97 pads and Boxster rear calipers with vented rear rotors.

(IMG:http://www.914world.com/bbs2/uploads_offsite/i.imgur.com-23854-1604589804.13.jpg)

I forgot to take a pic of the rear setup but its using RSR Boxster adapters


SUSPENSION

I decided to go with RSR Re-Valved Bilstein struts 220/100D for the front and Bilstein Rear coil overs. I started with 250 spring rates front and rear. I also picked RSR front sway bar.

TIRES

After measuring I settled on maxilite reps 16x7 wrapped in 205s Nankang Ar-1 100TW

(IMG:http://www.914world.com/bbs2/uploads_offsite/i.imgur.com-23854-1604589804.14.jpg)

SEATS

Sabelt X-Pad halo

I wanted something comfy and safe. This fit the bill nicely.
