OK Heres the deal I have a 2000 celica GT Signature Series and the signature doesn't make a difference in this matter I don't think. But anyways I want to know what would be the biggest horsepower motor that I can fit in my engine compartment even if I have to do a little bit of cutting to get it in. I want even maybe a turbo charged motor if possible, but not supercharged. If any, are there any motors that will fit right in that I can sup up a little more. Thanks!
P.S. if you know any little tweaks that I can do to my stock motor other than Intake
or exhuast let me know about that to.
