.....OK.....seriously? Those are just stupid nice. Man I wish I had a set of those for my car. But, alas, it is not to be. I have to try to keep it appearing as stock as possible - seats like that would be a huge give-away. But drooley.gif


Well, they bolt to stock seat rails. Easy enough to swap in/out. idea.gif
Just sayin'...

And thanks for the kind words but all credit goes to Stefan at GTS. I did spec them but, really, how hard is that?

Those are the nicest seats out there right now. Those grommets are incredible. Those seats are perfect size too.

Sweet cap screws!

If you're looking for an antisieze, DuPont Krytox works really well and from what I remember it's not too expensive. We specified and used it at a place I worked for pretty much all stainless, inconel, and titanium fittings. It was actually pretty much the only antisieze which always worked.


Thanks for the recommendation. Would you happen to know a product #? There seem to be a bunch of "grease" type products that come up when I do a search. Nothing specifically "antiseize".

Permatex makes a great anti seize that I've used on everything from automotive to semiconductor and medical equipment manufacturing. It's not expensive and it only takes a very small amount to work. Good luck!

OK, this may turn out to be a(nother) waste of time but boy, it sure would be great if I could run the intake in the "regular", not flipped, orientation. I'd gain all my trunk space back.

This is a pic of the Palatov DP2 set up. I don't (yet) see why I couldn't do something like this. I create a suitable bulge in the upper firewall and reshape the lower firewall behind the passenger seat to accommodate the air cleaner... Yes, it'd be outside the passenger compartment.

I'll look into it and let you know...
Cracker
A "suitable bulge" to accommodate that intake would be a "not so subtle bulge" - try it but I would bet you will find it to be way to deep. My intake is less than an inch off the firewall (and already sits 1.5" further back than yours)!

IDEA: What about making an "integrated" intake in the firewall? I thought of this when I was brainstorming during my build but it was well beyond my ability to pull it off. Piece of cake for you...

Tony - we may be thinking the same thing. When I say "suitable bulge", I mean, essentially, add a tunnel that runs up the fire wall, between the seats to provide the needed clearance. More as I try and figure out if it's practical.

Or do I go straight to ITBs... sunglasses.gif

Rather than adding a bulge to your firewall, maybe you can use a cobra elbow instead. Here's a pic that I found on the internet:

It allows a very short turn radius without significantly affecting flow rate.

Hi Bill. This is an interesting possibility. I haven't measured anything but my going-in assumption is that the main challenge will be making room for the drive-by-wire assy. It hangs out to the side of the throttle body and may interfere with the passenger seat. I suppose I could always limit the rear most seat travel... But the cobra elbow would likely allow a shallower bulge.
Thanks so much for the heads up!

I bumped my firewall out a small amount (1 1/4"), and it's goes un-noticed. The stock backpad still fits, though it does have a filler spacer. Point is, that it may be doable to run the intake forward and it's just a matter of how much do you want to bump out the firewall.

Hi Andy - Very nice. I just reviewed your build (post #23) and that's essentially what I'm talking about. Great to see others doing this same sort of thing!

This build is on hold while I get the '74 road worthy. Hopefully, that'll happen within the next couple weeks. Until then, it's "resting" in the garage.

And apparently, my wife thinks it makes a fine winter storage shelf for the patio furniture cushions.

Bella, my shop helper, shows great taste in selecting a Porsche perch for her afternoon nap.

Oh, and you can see that I've finally signed my sponsorship deal and have begun working on my race livery... av-943.gif

Nice! Did you cover a rust hole with that?
tygaboy
The LS car seems to be jealous. I was working on the '74 and learned that when a wire wheel gets hold of your work glove, it can quickly get scary.

I was cleaning off a small part with the wheel spinning such that it wouldn't grab the part. Well, there was a small lip that, in spite of my best intentions, the wheel got hold of.

A nano second later, the wheel pulls the part (and my hand) into the angle grinder. It ripped the glove and wrapped the cuff around the wire wheel, pulling the wheel right into my wrist. With the speed and force this all happened, I thought I was in serious trouble...

Thankfully, the wheel jammed up with the glove and stopped spinning pretty quickly.
You can see where I "got wheeled" and where the guard sliced into the base of my thumb.

In the end, nothing but a good scare - but certainly a reminder:

We can never be too careful...
Cracker
Chris - I am glad it wasn't worse but sorry nonetheless. Gotta be extra, extra careful using these tools, eh?

Thanks for the kind word (and the poke.gif ) Yep, I'm all good. So, let's get back to the build. This time, some non life-threatening stuff:

I pulled the trigger on my wiring today!

1. InfinityBox 20 circuit kit with:
- inReserve battery management system
- inLink (for security/imobilizing but I plan to run a "no key" solution. Just a push button start/stop button)

I'm REALLY impressed with the support. Jay has no end of patience and spent time explaining everything in detail. He even talked me out of buying some of the things I was considering. At this point, I'd recommend them, especially for builds like this one where I need ("need", ha!) to replace all the wiring.
http://infinitybox.com/

2. Current Performance LS3 stand-alone engine harness

It should all be here in a couple weeks. And won't this part be a ton of fun... laugh.gif

(Heck, I don't even know where I'm locating the battery!) wacko.gif

Not leather. I use those cheap-ish nitrile coated type. They work GREAT! Er, wait a minute...

Holy moley, it's been almost a month... And what I have to post isn't too exciting but I guess it is something, so...

The trailing arms haven't even been installed and I'm changing things already. I needed to rebuild the arms in my '74 so decided to pull the (new) Elephant Racing rubber bushings out of these arms, use them in the '74 and upgrade these to Elephant Racing PolyBronze.
The pivot shaft just floaty floats in there. You can spin it with two fingers, slide it out...
Zerk fittings are added as these needed greasing every 3k mikes or so. And yes, they change the ride dynamic.

So, there you go. Another month down but virtually no progress. I'm getting why it's called the Build Off "Challenge"!
tygaboy
Again, more time passes and not much of an update... With the shoulder injury preventing me working on the car, about all I can do is buy more goodies. I'm still in need of the torsion bars but this should be enough suspension porn to get me through my recovery period:
- Rebuilt/powder coated a-arms with Elephant Racing spherical bearings
- Elephant Racing bladed sway bar
Their stuff is so pretty I almost don't want to put it on the car! wub.gif
Curbandgutter
Hey it's nice to see some progress. Love the Elephant Racing suspension. They have the best web site don't they. That thing should ride really nice. No clunks or squeaks. On another note, Zero progress on my build for this month. I went on vacation and after I came back it's been crazy busy. I've been working all weekends. Anyway nice to see some progress....even if it's just buying stuff.
Andyrew
I must say the buying stuff is the most instantly satisfying part.. When you open that box and see those shiny (or dirty) parts!
tygaboy
3 months and no progress. Injury and other priorities... Enough of that! I'm back!

Here we go... I know that for some of you, this wiring stuff is nothing. That ain't the case for me.

For the most part, I've avoided thinking about this part of the build. Specifically because I have virtually no skills/experience with wiring. So, it's a bit intimidating looking at a two medium sized boxes full of the stuff. wacko.gif

For the main harness, I went with the Infinity Box 20 circuit with a couple upgrades. Current Performance supplied the stand-alone LS3 harness (set up for a reversed intake) and DBW throttle pedal.

With the arrival of this stuff, I have almost nothing left to purchase. What will I use for an excuse as to why this project isn't farther along? Oh yea, WCR prep! biggrin.gif

Good Morning,

In the box it looks pretty daunting. Once you lay it out on the floor it will get easier.
This is what we use at RS to put the wires where we want them. They come in both a large and small size.

I used the same when I laid out my harness. Laid out a sheet of plywood and put the harness down. It was extremely daunting in my project as I had a full modern day wiring harness to deal with (actually 3 of them)
After figuring out what I needed to I labeled everything and pulled it off or left it on for storage.

Are the wires all labeled ?

Looks like it. The Infinity Box box arrived last night and I just opened it. Haven't taken anything out of either box. The instructions look nice and complete.
mb911
Looking forward to see your progress the car is turning out very nice.
Mueller
Nice stuff there, I looked at the Infinity Box products for my other car a few times. Had I only had 1 project car instead of 2 I might have pulled the trigger and bought it. Too bad about their name, they used to be iSiS , which I see they still have on a few products!
Cracker
Well that looks familiar...the "40" has an iSiS system - still n the box - you will be a pro! biggrin.gif

agree.gif w/ Andrew. The plywood layout is infinitely adjustable and cheap. But more important is the preservation of ones own sanity. Start with what's easy or apparent. Then move on to the more difficult items. Often you will find that daunting items reveal their secrets, bit by bit, when working on some of the simpler items. Lastly, you will headbang.gif quite often. Get used to it but don't let it defeat you. Sometimes the answers will come at 2:30 AM, sometimes they come from this board or another, but they will come to you if you have the tenacity. When the moment arrives that you power her up for the first time you will be shitting in your shoes and thrilled at the same time. "Onward thru the Fog", Oat Willie.

So it's been months since I worked on this project. WCR and yesterday's R Gruppe gathering have me back motivated. Plus, I've gotten (almost) caught up on various other commitments that have kept me from this effort. Anyway... back to it.

First, something totally unnecessary that will only distract, add complexity and additional time to the build... Sounds about right to me!

I've decided to vent the radiator through the fenders and NOT do a vent in the hood (at least for now) and I'd like to do something to help with the removal of hot air from under the fenders.

I just love the fender vents in the GT3 RS so I hung a crap glass flare on the front and started drawing. In the end, this will be added to the steel flares - again, this glass flare was just for idea mock up. I'm thinking an aluminum frame with mesh. Ideally, I'll relieve the opening in the fender so the frame sits flush with the fender.

This was totally free handed (like you can't tell!). I didn't measure anything so yes, the openings are all different heights. That'll get corrected in the final design.
tygaboy
Then it was back to what I really need to complete next: the chassis.
I'm getting closer to what I think will be the final design/position of the front hoop. I want to get it ahead of the door opening. This looks like it'll require relocating the front hood latch release but that's not too big a deal.

Curbandgutter
I like what you are doing. At one time I was thinking of adding the GT3 louvers on the tops of the fenders but I am going to evacuate the air through the hood. I know that the guys that run the air through the inner fenders have the gas tank heating up from the hot radiator air.
Andyrew
So long as you duct the air from the radiator to the fenders there shouldnt be any reason why the fuel tank will heat up.

I like the idea of fender vents, I think the design needs some work unless your going for the mechanical look on the car. Cant quite think of a better design in my head though.... Maybe taper the bottom some more like the GT3?
Rand
Just a personal opinion, but on a 914 I wouldn't want the fancy vents. The stealth factor is what makes a 914 supercar so cool. Venting out the inside fenderwells has been proven to work. Out the top of the lid can make more sense for downforce, but to me, stealthy is cool. Nothing as cool as a monster sleeper.
tygaboy
Andrew - Yep, agree.gif the design needs refinement. As is usual for me, I need to see it, change it, try it, change it again. This is V1 so it's destined to be updated. From an overall look/feel, "mechanical" is actually something I'm after so I'm tickled that's how you saw it.

Rand - I am TOTALLY with you on wanting it to be stealthy. But I've always thought that once you add GT flares, 914s lose most, if not all their stealth. I was toying with moving the whole side of the car out 2" to fake a narrow body look and still have some tire to deal with the LS power. That's what I'd really like... maybe in the future.

So for this build, I'm going with a look that will be clearly identifiable as a "hot rod". That also opens up some other design options I'm looking to include.

Keep the cards and letters coming. In agreement with my approach or not, your input helps me clarify my thinking!
Rand
One thing for sure is we all have opinions, but your workmanship is stellar and whatever you do is going to be amazing. Speaks for itself. Keep it going and always express yourself! I always look forward to seeing your work.
