Just raced a Civic SI on the way home from work tonight. He pulled up next to me at 40 mph and gunned it, so I followed but couldn't catch up. At the next light we both launched and of course my WRX had about two car lengths he started to catch up but we were coming to the next light. I talked to him at the light to see what he had, cause I usually smoke Si's. He said all motor- heads,cams etc.. So we ran one more time- took him off the line again with a 3k drop- to give him a chance- let him catch up and then at about 50 mph we were even and I floored it but he started to pull away, next thing I know were at about 120 and he has about 2 car lengths on me.. It seems like the WRX has no top end, what can I do to improve it.
GFB pulley kit
Samco I/C hoses
