1991 Eclipse GSX, 122,000 miles (yes, that paint is original!)

Many of you are already familiar with the recent progress on my car via the two threads: Diary of a Rebuild and Diary of a Rebuild II.

This is my 2nd of 4 DSMs. A NT '91 Eclipse was my first car, but in 2000 I saw the GSX on a dealer lot with only 59,000 miles on it. I picked it up and sold the NT. Between then and 2002, the modding process was somewhat slow as I added an exhaust, clutch, boost controller, etc. My very first drag race was at the 2001 DSM Shootout, where I ran a 13.6 @ 100 and finished 4th in the autocross (also a first). I was hooked.

Since then, the car has gone through several changes and one blown engine (2.4L). In the past two years, the car has been running only a few months. Hopefully the new motor/turbo combination will last a bit longer.

Really impressive man, nice job!
AHHH!!!! I want my car fixed. Nice Work. Nice Dyno's !
I had some clutch slippage on the dyno and later on the street, after making the 627, because the organic discs I was using weren't up to the task. In the next couple weeks I'll finally get around to pulling the clutch out and sending it to PTT to get fitted with the metallic discs and a higher torque-holding pressure plate.

The power on the dyno was limited by my fuel pressure regulator, which wouldn't supply more than 46 psi of base fuel pressure. It's the old-style Spoolinup regulator, but it came with a stiffer diaphragm spring which I still have and intend to install. Once I get that and the clutch ironed out, it's back to the dyno with a goal of at leat 500 on pump and 650 on C16, which will be the limit of the turbo anyway. :)
Updated original post to reflect recent modifications.
You are an idol! I wish I could hit something that decent. I guess after I find a safc, injectors and fpr on a tuners budget I'll see what my car has....

i see that you are using a nt tb, did you just get a 1g's nt throttle body out of a junk yard, replace the seals and put it on? Or did you have the shaft machined to put in the turbo seals to help it seat better?
I didn't have anything on the TB machined.
do you know if you used the same o-rings from the turbo throttle bodies? Yours held 600+ to the wheels and people were saying that these will leak, im sold after seeing that. time to hit some junk yards
It was a long time ago, but I think I used the seals from MachV. It leaks a tiny bit but it's negligible.
I'll count myself lucky to have seen it actually run and drive around. I did have to keep myself from drooling a little.
Heh, old thread. :)

Who is this?
You should post some pics. Link don't work
