My New 1993 Z28 Project
I started with the angle grinder on cutting the inner fenders as he took the driver's side off.
This is what it turned out like:

I then drew templates of the passenger's side and cut them out while my friend taped off the area and painted it flat black. We did that because I noticed all the metal shavings from the day before had completely rusted overnight and I didn't want to leave the fender area open to potentially rusting. I then drew the templates on the passenger side, but decided to wait on cutting it because Jason's car was right next to mine and I didn't want to shower it with sparks. I'd already moved one car and didn't want to feal like I was in the way. I'll finish it next time.
After that I decided to take the driver's side header off to mock up the header I found that looked like a good potential turbo manifold. The front bolts were easy and really loose. I got them all out really easily, but then.... I figured out why who ever started to doing the headers decided to stop.
They broke one of the freaking bolts off in the head:

I started trying to get it out, but it was tedious work. We let the paint dry on the fender while we worked on it with vice grips. I tried to get the hooker shorty out of there with the bolt still stuck in the head, but it stuck out just enough to prevent me from extracting it. I got the bolt out a good ways, but by the time we had to pack up it still wasn't all the way out. We were getting sick of messing with that so instead we reinstalled the passenger's side fender. We were concentrating on getting all the gaps just right. Despite being very difficult to accomplish we got all the bolts in the right places and the gaps just right. Next time I go down there I just have to tighten them down and reinstall the plastic inner fender.
Here's a picture of the header I found that might work as a turbo manifold. It has 1-3/4 primaries and is square port, but it should work with some rerouting of the back primary, a new D port flange, and getting rid of the ABS block which I planned on doing anyways.

New Questions:
1. Anyone know of a stock ECM 93 turbo car or the difficulties of doing this?
2. I plan on using the hooker shorty on the passenger side, but it has 1-5/8 primaries. Does anyone see a flow issue here? I don't know how well it would or if there would be any problem at all using a 1-5/8 primary with a long crossover with a 1-3/4 primary with a short tube to meet with the crossover.
I unplugged that thing and climbed under my hood for rain protection. I finished getting that bolt out of the head. I then tried to pull the header out, but it was stuck against the steering rack. It absolutely would not come out. No matter how I pushed, pulled, or finagled the thing it was stuck. Eventually, I had to take out the center wobly part of the steering shaft to get it the header out. During which time I noticed that the bolt I had extracated wasn't the only one that was stuck. The absolutely very last bolt in the back had broken off inside the head.
I then tried to mock up a bunch of different header options for the turbo setup. The original manifold I planned on using was way too wide and wouldn't even fit. I dug around the shop and found another one. I slid it in and bam, it works quite well. I'll still have to reroute the last primary as it hits the steering shaft, but at least it fits. Another nice thing is that it doesn't use the very last bolt in the head so I don't have to worry about getting it out of there any time soon.
Here's a picture of the new driver's side header:

I'm still in kind of a quandry over the passenger's side. The problem is I want to keep the ac and power steering. I tried the stocker and the hooker shorty I have. Both of them kind of have the flange too far back. Ideally, I'd like to run the crossover under the oil pan in front of the sump. The way it sits now it's kind of far back, but I'm not sure. I didnt' get a chance to get under the car as my work area was completely flooded again. Jason said he has a set of block huggers some where around the shop that he thinks would work on the passenger's side. We didn't locate them, but have an idea where they are.
I have the driver's side header with me. I'm going to take some measurements and order an extra couple feet of tubing in the same size and a D port flange. I'm I have to work on Thursday, but I should be able to head down all day on Friday and see what I can get done.
Thanks, and will do.
Yeah, this one might sit for a little while, this turbo stuff is extremely expensive. I really want to get my Formula operational. I still can't believe it did that. I've only heard of one other person who had something like that happen.

The only part that sucks is it isn't as the guy said it was. He said it was fine, but it definetly has some shaft play in it. If I spin it a certain way I can hear the blades just barely touching the compressor housing. I took a video of it on my phone and sent it to my email, but I can't watch it. It says I have to download some video player and gives me a link, but the link doesn't work. If anyone lets me know how to do it with a tmobile phone I'll try and get it operational. All in all I'm pretty happy for getting it for $600.

I should have bought a damn Pinks All Out ticket when they went on sale. I didn't think I'd have this done by then so I didn't. Now they're sold out. I'll probably still head down there as we have a few shop cars that are going. Jason's taking his 95 Camaro LS1 turbo car (http://www.modernperformancetech.com...?p=492#post492) and my friend Ryan is taking his 95 Camaro 396 Gen I SBC car (http://www.modernperformancetech.com...?p=473#post473). Both should be in the 10.5-11.0 range.
I was too until I saw that this turbo weighs about 45 pounds. Doh! It should still weight a lot less than I started with once it's done. I'm thinking I can take about 100+ pounds out of the interior.
Correctamundo. We can pretty much get away with what ever we want down here. It's quite nice.
Yeah, the 45+ minuted drive down, then back is always fun.
After getting the front end back together we tried to start mocking up the turbo set up. During which I basically messed up the alignment big time. I had taken the flex section out of the steering shaft. I was trying to turn the steering wheel and the flex section came undone. I was pulling on it so hard that when it came loose the steering wheel spun around about 30 times. When we tried to put it back on the steering wheel was upside down. OOPS... I'll fix it on Tuesday. Onto the pictures:
Here's how the driver's side header fits. It clears everything, but the steering shaft nicely.

This is kind of a crappy picture I took, but here's where the turbo is going to go. I really need to get rid of the abs block. As you can see in the back it's hitting on the turbo. I need to order a proportioning valve and chuck that thing. I'm also going to reroute the fuel lines like LALT1's thread. I don't want those lines close to a nuclear hot turbo and it'll look quite a bit nicer.

On Tuesday I'm going to try and reroute the fuel lines and if I can get a proportioning valve by then put that in also. I'm going to fix and get the steering shaft bolted back down. After that I'm done under the hood other than getting the turbo set up. Then it's onto the interior and cutting out all the old useless wiring. The coolest thing that happened today though is my friend Ryan said he'd give me all the interior panels and seats out of his car. Which is absolutely awesome and I've got to give him major props for helping me out big time.
