Well THARS your problem!!
If you splice the 13th blue wire from the bottom left to 4th red wire on the top right, cut and ground that brown one right in the middle, you'll be ready to race in no time!!

I hear you. I was a little blown away by the amount of wiring I found when I removed the stock dash. The good news is most of that will be gone. Creature comforts are for the weak!

I received some more goodies in the mail over the last couple days.

My Melrose LS1/C4 swap headers came in. I am impressed. Build quality and hardware are top notch! I ordered mine uncoated. I want to go flat black with them. I intend to use header paint. If that fails, I can always get them coated later.

I also received my C5 front brake brackets. I got them from a forum member. Again, build quality and hardware were impressive. I mounted them on some 85 spindles I picked up (because 84s have smaller/weaker mounting bolts). Although I do not yet have my new rotors or hub/bearings so a full mach-up will have to wait.

Spindles came shockingly clean, and cleverly bolted together for shipping.

Also, since I have the D36 (and entire rear suspension) out... I have been drooling over Banski Motorsports' C4 rear suspension parts.

What can I say... I have a soft spot for quality USA made parts!

great build! I had a 1990 c4 and loved that car! I had a z07 suspension on mine and it handled amazingly well, that car never leaned. Wish I could find it out there now, would love to put an lsX and t56 in that chassis.

subtlez28 · 07-12-2010, 07:33 AM

Thanks. I recently sold my (subtle) Z28. So the rush is on to finish this build. I have done a bunch of work. When I get a little free time I will update my progress w some pics.

Here is a teaser:

I have the entire rear suspension out (actually the entire drive-line) along with the rear facia, bumper support and gas tank. The New (to me ) D44 was checked out at the shop. Banski rear suspension is in the mail.

I have finally started the re-assembly process by installing the new Classic Tube fuel line.

The rush is on. I hope to race the car at 2 events in September.

merim123 · 07-12-2010, 07:35 AM

wow - all in your garage too, without a lift, very impressive. I like the way that car sits in the initial pictures you had too, looks good with the z06 wheels, keep those if you can.

subtlez28 · 07-12-2010, 09:03 AM

I agree the Z06 wheels looked good!

It should sit the same (it had the LS1 in it - just not running and w an auto), but I sold the Z06 wheels. I am running 17x11s and 315/35/17s all around.

merim123 · 07-12-2010, 11:05 AM

so are you upgrading the look to 92-96 style or...

c5 on c4 conversion

subtlez28 · 07-14-2010, 09:34 PM

No appearance mods planned, except maybe GS flares (to cover the 11s) and maybe flat-blacking it. This will be a track car. It does however have a nice, cowl hood.

subtlez28 · 07-29-2010, 12:10 AM

Well, I have been working on it some lately. I haven't had as much time as I'd like for photos and posting, but here is an update:

The Good news:
I have finally started reassembling things!
I have the new Classic Tube fuel line in (which required the whole rear of the car off give or take).

I took off the rear facia (nightmare). Lots of hard to reach bolts and sweat and blood involved...

And dropped the rear bumper/gas tank assembly:

More on the gas tank in the bad news section...

I have had some help in the garage today in form of my 7 year old son Patrick!

So I was able to get all rear suspension back in. I replace all the consumables: new SKF hub/bearings, ARP wheel studs, Spicer U-joints. I picked up the whole rear kit from Banksi: rod ended camber rods, toe kit, and trailing arms.

I deleted the dust shields on the rear brakes, and I think I'll leave the rear wheel wells off.

Bad news:
When I dropped the tank I found the sending unit rusted to the tank. Two of the bolts snapped off. The sending unit was bastardized like the fuel line (pump replaced w hose). If you remember from early posts they also cut up the factory hardline to put an external pump under the rear axle...??? I have no idea why when the car has an internal pump. I intend to replace it with a nice Racetronics kit.

I do have a new sending unit from Corvette recycling. I just have to clean up the fuel tank 1st. Oh, and did I mention my local radiator/gas tank place stopped boiling tanks two months ago?!

merim123 · 07-29-2010, 08:10 AM

it's looking good, like the suspension! can you get a newer gas tank from a 95/96? there should be enough of those in the yards.

I know it's a track car but I'd still say put a 91+ rear bumper on it

, I never liked the 84-90 rear, when I had my 90, i always wanted to replace that rear bumper.

subtlez28 · 07-30-2010, 09:14 PM

I did some work on the gas tank today. I drained it as much as I could and washed it out w water days ago. It still smells like gas but is dry. I was worried about going after the rust (explosion). Today I bit the bullet and hit it with a plastic media wheel on a drill. It cleaned up well, and no sparks...
I threw a quick coat of paint on:

Down side is the cheap bolt extractor kit I bought at AZ did not help w the two broken bolts. However I did bust several drill bits... Those tank bolts are hard!

I switched over the wiring on the late C4 sending unit. I just pulled the factory wires from the old 3 plug connector, the new 4 conector, and put the new unit wires in the old (3) connector. The new sender didn't even use the 3rd place, so I think I'm good.

I also put in my Racetronics pump and sending wiring (just 2 splices - it was for the 84 sending unit).

xpndbl3 · 07-30-2010, 09:49 PM

looking good man, you expect to have it out this season at all?

subtlez28 · 07-31-2010, 06:23 AM

I'd love to have it out for the HPDE and High speed autocross in early September. Not to sure on that though. Midwestern Council has another event in mid September and early October. I really think I can make those...

subtlez28 · 08-01-2010, 09:43 AM

I got my new (to me) harness in yesterday! I originally had an S&P harness for the LS1 and 4L60E that came in the car. I was going to modify it for the T56. But then I found a great deal on a used S&P harness for an LS1/T56 combo, so I jumped on it.

For anyone doing a similar swap with an auto, my other harness is currently in classifieds.
$650 shipped.
