I'm mostly quiet and read a lot on here because I don't have any knowledge with S/C engines. To recap, I bought a 2002 GTP with 158k miles on it. Gave it to my mechanic and sank $1300 in getting her running correctly. (Don't worry, I didn't give much for the car.) Now that read through bluegtp91's sticky a bajillion times (Thank you SO much for that), I think I'm ready to move forward.
The car is a DD and I'm not hard on the car. I never plan on taking it to a strip. I just enjoy annoying the local hondas and F&F crowd.Previous car was a 04 WRX wagon and I know this car is faster than it was. Not from a dig but a roll, it would smash it. The mechanic says the engine is in beautiful condition.
Ok, I'll get on with it.
What I'm looking at is moving to a 3.5" or 3.6" pulley. Don't really want the 3.4" as I'm not trying to push anything, I'm just trying to breathe a bit better. (I have a long history of turbo cars.) I'm looking 3.5" pulley, 3" DP, PLOG, and supporting mods for that such as plugs, open cone, t-stat and tune. The tune will be done by my mechanic. He owns a speed shop and tunes regularly.
I know the headers are cheap and better than the PLOG but I sort of like the stock/sleeper look of the PLOG. If my goal is a slightly quicker DD, does my list look correct? If I've read the sticky correctly, I should be ok but I thought it wouldn't hurt to have some more experienced people look it over compared to my goals. With the list that I'm talking about, how much gain should that be approximately good for? 30-40WHP maybe?
Thanks for double checking me. I'll take any helpful guidance I can get. here to learn.
