my friend has a ek cx hatch with a ex tranny and manifold with a xs power t3/t4 turbo kit, arp head studs, and cometic head gasket.

so i was wondering if it would be better to run a zc head if you could or is just better to run a vtec head and which would be better out of the two if the zc fits

thanks

Put a cam in it. Y7 head has VTEC sized valves...

 

but how much faster would it make compared to a vtec head

 

Depends on the cam. Only thing VTEC is good for is economy.

 

so vtec doesnt make it any faster? and also what cam would you suggest and how much would that run?

 

VTEC is just a different cam lobe for power. Same thing as a big nonVTEC cam.

Delta 260 regrind has worked good in small turbo setups. There are a couple companies that do custom grinds. If you have money, Rocket Motorsports can do a custom grind for you.

 

well this is not my car or setup and my friend doesnt or cant spend really more than what a y8 head costs cuz he has to pay bills and what not but where could you get the delta cam
