Turbo selection

[twinturbo69]

Having power hit like a sledgehammer may be completely fine on the street if you tend to point the car in a straight line, but certainly less than optimal while auto-crossing. I have smaller twin T04Bs (60mm compressor wheels, P trim 0.69 A/R hotside). They aren't as effective at building massive top end power as much as building boost right away when I want it on the street. For an autocross car I would look at a turbo that is easier to control power delivery and might consider a boost by gear setup to regulate the power delivery.
