With the turbo ls you should be in the 13's. It is a pretty reliable setup and a lot of fun. And where did you hear that turbo d series is better than b16 turbo, lol thats a load of bull. Turbo b18b on 8 psi will have you above 200whp, turbo d16 on 8 psi will have you at about 170whp. The d series is a waste of time you will enjoy a turbo'd b series so much more.
