What about intakes and exhausts? That's like $250-500 per 1hp, LOL.
But on a serious note, go try and push +50-75 hp reliably (on a Japanese motor) and tell me how much you spend; I wouldn't be surprised if you end up right around that ballpark when you're all said and done. All the little things here and there add up, and add up quick. Gotta pay to play, good sir :yo:
I understand what you mean though, when I look at those commercial supercharger kits out there for all them 'merican muscle cars (that gain you several hundred horsepower for about the same price), these TRD supercharger kind of look like a huge rip off, lol.
That's why I've decided I am not going to bother with a TRD supercharger if it ever came out. I think I'd rather invest in something with a HEMI and supercharge that :usa2:
