First the facts.
Euro engine has 263hp and 251 torque, is 2.0 litre engine and has a 7,500 rpm redline.
USDM has 300hp and 300 torque, is 2.5 litre engine and has a 7,000 rpm redline.
Now from what i understand the 6 speed gearbox in our car is the same gearbox in the much different Euro STI. I mean it has the same gear ratios and everything. So am i wrong in thinking that this gearbox is a mismatch? We should have our own gearbox with ratios for our engine in order to maximize our engine's abilities... right? Let me know if my info is correct/incorrect and what your opinions on this are.

STi and IHI VF30 turbo

Just because you have more power doesn't really mean you'd want to change the shifting points. All that would matter is that the RPM ranges are the same.

You wouldn't go taking the STi tranny, which is mated to an engine with a 7k redine and put it in my Celica, with an 8300 fuel cut.

Other than that, I think you're ok.

Ummm...I could be wrong but I have seen it posted a few times here that the gearboxes are not the same at all. They have completly different ratios...Maybe I am thinking of the Jap STi :-?
