the kit slapped on no tuning expect at least 200 whp. Afc dyno tuning expect about 230whp @ 8psi. Hondata 2b expect even more. 8psi should be mid to low 13's on street tires full interior. A guy from houston has been doing crazy stuff on stock internals. Something like 300 whp @ 18psi with only hondata and block guard. Any kit with t3/to4 should do. Dont get greddy. Good luck.
