Where did you hear that you cant do any of the above? Go turbo and run a piggy back. Find a supercharger kit. Swap a 2zz and figure out how to get rid of the CEL. Of course doing any of these will require a pretty good deal of money. If you want just little gains for little money go for intake and exhaust system. I think if put lots of racing stickers, prime your car and leak your exhaust, you can get the attention youre looking for at very little cost. I hope this is the little help you were looking for.Unfortunately I have a Sequential Shift Tranny so a motor swap, turbo, supercharger is out of the question. Was looking for a little help.
