alright guys, here's the deal, i've got an 99 gs auto integra, and i want to get a vtec head, but the question is, which ecu do i get? or better yet, can i even get a vtec head for that auto ecu? eventually i'm going to convert the transmission to a manual, but i want to do a vtec hybrid at the sametime too, so should i just wait to do the gs/vtec until i do the auto/manual conversion?

 

hello, anyone know of this answer or no?

 

You make it easier on yourself, I would do everything at once. If you do that you will spend less money. I would get a P28 so that you don't have to wire up knock sensor.
