If you would take into context what I said I meant that what I had to say was a SUGGESTION not a recommendation. I do not want to be treated like royalty at all WISE ASS!! Dont ever again refer to me as such. On another note just because I am in the service doesnt mean what I have to say is always right. We as soldiers can be wrong too. DUH look at the middle east and all that cluster fuck.
Anyway please dont take into offese what I have to say. If you or the guy who originally started this post or the other guy asking questions wants to tune a D series or a B series by all means take in all suggestions and make a choice for yourself. Thats called research.
As for the ZC question your going to need a V Tech ECU no matter what. The car will run like dog shit if you dont use the right parts. Sure you can swap the head onto the car but in order to do it right your going to need the ECU and depending on your motor and current set up a few other things might be neccessary. What are you running now specifically?
