We did one all motor RSX. The guy screwed us over on $1500.00 in labor and parts. We put higher comp. pistons, and did some major head work. The kid writes a chk. and then stops payment on the chk. the same day. When we did have the car for tuning and test it pulled real hard. The turbo RSX we used SDS come by the shop and talk w/ Dwight he'll let you know everything on that setup. The turbo car would pull hard in every gear. We "tested" it against my DPR stage 5 head GSR in a 92 civic coupe. The RSX killed the car by at LEAST 15 car lengths.
