Hey this is my first post here i just got a 93 prelude si 2 months ago and i was thinking about swaping the H23A1 with the vtec. Some of the questions i have are is the vtec wiring alredy in the 93 si or dos it have ot be 94 and up becuase i have herd both? And will i be able to connect it to the si tranny or will i have to get the vtec tranny? And is there any other parts liek the ECU ill have to get for the swap? im 17 years old and jsut geting in to the car bussines and loving it so i might be some what of a "NOOOB".
