Ok I have just purchased a 91 Civic HB and it has a b18b LS motor. Will I still be able to turn the LS into an LS/Vtec swap? I want to out the b16 head on and the b16 tranny sense the trans is more tuned to run in the 1/4 mile. What all will I need to do to turn the LS into and LS/Vtec? Ex, pistons, ECU, Cams, and especially now will the Vtec wiring harness fit?
