can you guys help me out here.. i would like to transform my celica from just a plain jane everyday driver to a performance driver.. i would like exhaust but i cant find any that would fit my celica
i would like turbo but also can't find anything to fit it. so can you help me out with like brand names and such or links would be appreciated.. thanks

You can't just fit a turbo without modifying the engine heavily, you would be better off selling you celica and buying a celica GT4 turbo.
This is already modified with most things you need and puts out about 220BHP standard.

as for the answer above me.....have fun trying to find a gt4 thats not garbage. suggest ditching the motor for a 3sgte, which is the factory turbocharged 4 banger used in the gt4 and the mr2. be alot easier and save yourself alot of time and money modding your existing engine to take boost when you could just buy one out right
