Vtec questions w/EX and LX
 

Is buying a D17A2 vtec head all i need to convert my LX engine to EX and get it to the EX stock 127hp???
Or do i need to buy anything else to make the install work? Im thinking of finding the part in a junkyard and changing it on my car, then adding stage 1 camshafts (and maybe valvetrain kit + pistons and Apexi S-AFC2)
I think doing this will add some serious gains. If the head is all i need i will have 12hp more and then another 8 or so w/stage 1. Thats 20 on top of the basic i/e/p set-up i have now.

what do you guys think>?

Hey Idon't really have an answer but this is the way I understand it from what I've read. The vtec only starts around 4000 rpm where ecu tells the valves to open a little more giving you that extra kick boost / whatever. there is a mod I've only read about that make the vtec kick in sooner so you don't have to wait so long. If this is true than you have to conclude that you need the ex ecu.

I'm about to put a ex engine in my lx. I'm hoping to write up a basic how to with pics. since no one seems to know anything about these too engines compatibility.
