arent the cx heads 8 valve slow asses?

id rather get a 16 valve head vtec or not

 

i just put a y8 head on my built y7 block. its a pretty straight forward thing. well worth it

 

But what about software? Doesn't the y8 need a different ECU over the y7?

 

no you coud use a rpm switch or vafc

 

Pardon my ignorance hotrex, but wtf is a VAFC? And does anyone know how much $$$ an rpm switch and/or VAFC goes for?

 

STOOPID N00BY BIATCH! U DON EVEN KNOW WTF A VAFC IS?!? GO AWAY LAME *** RICER/WANNABE!

I just had to flame myself because I really don't know squat about engine tech

 

read read read... there are a lot of good answers out there for you... just keep reading and you'll be smarter soon... don't do the head swap, just save for turbo... you'll be happier.

 

rpm switch = about $45 no adjustability, set rpm
vafc = $200+ as much adjustment as you want, plus can be used for turbo fuel management in conjunction w/ larger injectors.

they both will control vtec if you have vtec but are using a non vtec ecu.
