i dont know much about car but enough to get me by and build up a couple ok ones but due to the rise in gas prices i relize im stuck with the 94 celica st i bought to beat around in til i found a new toy but its to slow and i mean its really slow and unforchuntly i cant find any real performance parts just body kits and so on does and one out there know where i can find stuff to build up the engine a bit? i want to try to get the most out of it without n2o or a turbo

I would call around, check out a few parts stores, and then I would check out a few aftermarket performance stores, maybe ebay, and jcwhitney

ebay has intakes and headers for st's. and im sure you could find an exaust system somewhere if you search.
