I've only done performance mods to my car, but cash kinda ran out before everything I had planned got finished. Regardless, it's still fun.

3.8K motor
rebuilt tranny to HD specs, 3500 stall converter
Paxton Novi 1000 supercharger
33# injectors
reflashed PCM, raised shift points, no rev limiter, raised trans line pressure
CAI
colder plugs, thermostat, yadda yadda

I'm only running 6lbs. of boost right now, because money ran out before I got headers or a downpipe, and I can push that through the stock manifolds. Right now my car isn't a priority, but if I ever have an extra couple hundred bucks, I'll probably buy a set of ported manifolds and a downpipe just to get the exhaust flowing a little better, and I'll be able to drop down a pulley size most likely. I also have a lower intake manifold that I wanted to port, but haven't been able to. I did a home polish job on the throttle body, and I have an extra upper intake to fool around with once summer rolls around again. I no longer have a garage to tinker in

I haven't had it dynoed, but judging from other cars similar to mine, It should have about 200 horsies at the wheels, give or take. My car will pull a bit on my friend's stock GTP, whichhas a roots blower, so it might have a touch more power, but who knows.

Originally I was going to intercool it, and build a motor for it with a nice bumpy cam and whatnot, but that didn't quite work out. Now I think I'm just going to get the exhaust done, drop the pulley on the supercharger as small as I can safely, and leave it alone. I don't have another few grand to drop a built motor into it as well.

That's quite a mod list there, I'm impressed. My cousin and I raced a GTP in his modular Fox and pulled on him pretty well last weekend.

Why all the money dropped into a FWD slushbox?

Well, I've always liked the car, and no one expects there to be anything done to it. I like larger, four door vehicles, and since I also am a youth leader in my church, I need to have room to haul kids around as well. It's practical and fun. Perfect for just driving around town.

It really wasn't all that much money, either, at least comparitively speaking. The tranny already needed a rebuild, so I just had to get the torque converter, HD diff and output shaft to go along with it. Then, I bought most of the stuff second-hand, including the supercharger kit. I got the kit for $1800, I think, and got the injectors for $40. The PCM was $250 and then another couple hundred on a scan tool, AFC, plugs, that kinda stuff.

I mean, I'd LIKE to have a RWD V8 with a 6 speed, but it's just not practical for me, so I decided to just mod this car and keep it longer than I normally would.

Yeah, the GTP's aren't terribly fast, about mid 14's stock. Mine should be good for a 14 flat, so they say. I don't have a track anywhere near to find out, though.

Once I get my living situation straightened out, I'll probably pick up interest in it again. For about another $600 I can get all my exhaust done, drop a pulley size or two, and it should be good for mid 13's.
