that turbo isn’t too big for that size engine. You’ll be fine.

i hope not, btw by "to big" I'm referring to not being able to start making power from around the 2-2500 range. i have a Vs racing 80mm with The v clamp, turbine housing A/R is 1.30. So far i am not impressed. But I'm hoping it is because of the tune.. more so the spark advance isn't correct.
