I don't remember what the coils themselves cost. It wasn't much, but Claudio talked me into them when I bought the Haltech e8. The coil bracket was free. One of the perks of being an engineer in a manufacturing plant with their own machine shop.

Nights and weekends I work at a local fabrication shop. Mostly, we do industrial stuff like semi-beds and pipeline stands. On rare occasion, we'll do rollcages and other hot rod related stuff. It gives me access to some pretty neat equipment and lets me get quite a bit of fabrication practice.

If you take the car to shows you will have to film reactions, I imagine you will get some good ones.

Did a little more work on the car. I am planning on having the Big Bore modification done to the RE throttle body. Did a little reaserch on this forum and decided it was rediculous to run 3" intercooler piping, neck down to 2.5" to mate to the intake elbow, and then neck back up to a huge throttle body. It looked at what other folks were doing and welded some 3" aluminum pipe to the intake elbow and then bead rolled the end.

I welded all of the unused vacuum ports on the LIM, UIM, and throttle body (there are 4,195,546 of them!) The lines going to the wastgate & solenid and the BOV are all -AN. I'm trying to keep as few rubber lines as possible to minimize the chance of one blowing off at high boost. The only lines that need to be rubber in my application are the MAP and Boost Gauge. I wanted to use the fittings at the back of the UIM so they could pass through the firewall with as little showing as possible, but the nipples are just straight tube and are much too small for the MAP. At first, I pulled out the stock tubes and tried to drill and tap the locations for 1/8 NPT. Blowout! I figured I'd just weld up the holes and tap a little higher, but that is right where the division of the Upper/lower ports is. So..........I built up the edge with weld and contoured it to look like this......Pain in the @$$!

Keeping in-line with trying to have as few non-AN fittings as possible, I read a post that said an Accufab GM IAC Motor to FOX mustang adapter might work on the RE throttlebody. Money! So I punted the Haltech IAC adapter stuff I made earlier and am going with this setup.

In fact as far as muscle cars go, you can say you have a micro block!

I've been doing quite a bit of reaserch on exhaust manifold design on this forum and have realized that my design could be greatly improved upon. So, I'm remaking the manifold using the following criteria.
  • Equal length primary tubes
  • 2" Sched 10 304 SS Primary tubes
  • At least 3" of straight pipe after the exhaust ports
  • Dual wastegates for total runner division
  • 13-18" primary tube length
  • Bracing at the turbo flange
  • Turbo location to allow for 3" to 3.5" downpipe expansion
  • Turbo location to allow for at least 4" of straight pipe on the downpipe before making the first bend

Going to get started tonight.

The shop that is doing it does regular bodywork during the day and restoration work at night. It's a very labor intensive process to do a full strip and then do a show quality paint job on the underside/inside/and outside, especially when ghosting in graphics.

I think I would go with a set of 4.11 gears instead of the 4.88 since you are going turbo. Nice project. Keep it coming

I figure I've got enough tire so why not. In all of my past cars I'd always wished I'd had more gear. We'll see how it works out.
