Need info.

[Evangelion]

Hey all,
Need some info, I'm looking to get a 2000+ Toyota Celica GT. What all can be done to it PERFORMANCE wise? (Besides engine swaping and internal upgrades). I've already seen the obvious cold-air intake, headers, short shifter... ect. But I'm wanting to see if the celica GT has a turbo some where out there, and stuff like that. Anyways, because I know very little about Toyota's, Celica's espeically, I would also like to know of any and all websites that lists the different engine codes, tranny info, and physical specs of the car. Also I welcome any and all info about problems that are well know of the 2000+ Celica's both stock and any info on upgraded Celica's.

Thanks for your time.
