Hi,I am new at this forum and this is my firs post. I have a 92 prelude SI which comes with H23A non v-tec I want to swap it with a H22 V-tec (is the JDM spec same as the US Spec?) What will be the major modification that I will have to do to my car, or is it just a bolt on modification. From what I have heard is that the 1992 si comes prewired for a v-tec engine but for some reason that engine was never released in the US for that year. I like to hear from someone that has already this swap and can tell me exactly what the modifications will be. One more thing, will my car still pass the emissions test in california after making the swapping? Than you very much, any info will be appreciated.
