hi, im rebuilding my b18b block at the moment pretty much OEm rebuild with ARp rod bolts and ARp headstuds,cometic headgasket (for boost) and for the head im not sure on what to do i know i want to buy some cams for this LS head but what else do i need to modify to cam this LS? can u guys post up what setup you went with for your ls/b20 head? i heard that the 403 all motor cams work great tuned under boost need some input please post up what cams your using and if you left your valvetrain stock or not thanks for looking. oh and this is getting boosted as soon as im done on hondata s300. thanks for looking

 

it depends how much power you want. But my bro made 400whp @ 20psi with brian crower cams and the whole supertech valvetrain on his built ls if that helps you out. That was with a sorry *** set up too (cheap ebay turbo kit) and 2.5" piping with a restrictive sucky muffler lol. Now he has a top mount with a gt35r and 3" piping with a vibrant muffler but he hasnt put it on yet and tuned it yet but I'm sure he'll make a lot more power.

 

i thought that crower made turbo specific cams. their turbo cams have significantly less overlap.
