Re: H22a in 91 integra
What I would do:
-Forced Induction:
B20B long block, Jackson Racing supercharger or DRAG turbo setup, LS cams, LS intake manifold, GSR tranny, LSD-maybe Type R, GReddy e-Mangage or Hondata & an ACT clutch.
-NA:
B20Z longblock, B16 LSD tranny, Crower 62403 cams, Crower valvetrain components, Skunk2 IM, H22 TB, DC header, reprogrammed ECU, & ACT clutch.
headwork- valve job, porting and polishing, and gasket matching the ports on either, if you want to spend the extra $ and do it right for either one.
Pistons- 9:1 for turbo, 11-12:1 for NA
