ok i searched and couldnt find what im looking for.
i have had the block decked, honed, cranhshaft ground and polished, and have forged pistons and rods and a block guard.
i wanna do around 350whp daily turboed of course so my question is as follows,
i dissmantled the head and didnt mark were any of the valves came from, first does this matter?, and can i still use my stock valvetrain without risking anything breaking or should i upgrade? id prefer not to at this time if its not absolutely needed. and if i can use my stock stuff what needs to be done before i put it together? right now its been baked or cleaned, exhaust valve guides have been replaced.
i will be using my stock valves for my build up(350-380whp)
setup…cp pistons 81.5,eagle rods,stock block,p&p head,crower dual valve springs and retainers with 403s…
I’m making about 450whp stock head except supertech valve sprigns and retainers. everythnig else stock. reving to 9090 right now which is no problem for a stock 01 itr head either tho… but Plan to keep reving it to 9500+ soon
radioactive77 , are you talking about a Vtec head or Ls head? I am aiming for 400-450hp right now with a ls head, and I have an upgraded valvetrain. I think if you go all LS, your definately going to be needing that upgraded valvetrain.
if you build an ls head, go with the crower springs/retainers and the 402T cams. aftermarket intake manifold will help, ive seen dyno charts of ls’s with that head setup making 20 hp per psi
if you are vtec, use oem itr setups, or if you are really racing the shit out of it, you want to use aftermarket retainers and springs, because the boost pressure on the valve will pull the keepers through the retainers, happend to someone i know.
