i was looking through ppls builds tonight and i have come to see people do the springs and retainers. But is it even necessary to upgrade your valve? most cams say to just put in new retainers and springs but no valves,


its it a good idea to do it or just use the OEM valves.i would say yes if it was a high comp. build but for a boost set up ehhh i don't know


ALSO i cant remember the ZEX cam for a Y8 can some1 tell me what it is again

i dont have a turbo but i recently upgraded my valve springs and retainers. When i took my head apart the valves had so much shit built up on them. Ne way,cleaned em and they look brand new. My point being,there really isnt a real need to upgrade the valve unless you building an all out race car and every mili second counts

crower n/a = AMAZING

crower turbo cams.... not so much.

jfk picked up 40whp @ 8k on his y8..... zex cam, h22 tb, and a skunk 2 intake manifold.

you tell me which cam is better.

zol (reaction 360) also tells me ho the croer turbo cams are for like 150-250whp. very restrictive up top and for more then 250whp cars

I got a set of Supertech valves only because it was a smoking hot deal through a seller on here. I've taken apart a few heads before and figured if I'm spending all this money into new springs, retainers, 59300...why not get valves? Everything will have the same mileage and will break-in smoothly together.

But yeah, OEM valves will hold up to boost just fine!
