hey.. i think im forgetting something..
im doing a head swap on my crx..
im going from HF - Si,, i just can't remember wat im missing..

head.. wat else..??
please help im doing the swap tomorrow..

 

please some one respond...

 

um i think full mpfi swap not sure
do some research on which t best to use
u def need a pm6 to notice anything

 

I am pretty sure that HF is already MPFI......but doesn't it on;y have 8 valves? I don't think you can just slap an SI head on that guy because the pistons are only made for an 8 valve head and there would be no grooves for a 16 valve head and you will have som clearance issues....once again I am not sure on this so no one quote or flame me please I am just tryin to help out.
