40psi huh...wow...your talking about headgaskets and lifting the head now..

why not get something you can run 15-20psi on...and still get you the HP you want.


honestly my outlook on some sort of turbo setup on a honda would be nothing less then 1.8L with all forged internals...youll never run twin turbo on it. if your worried about lag, then go 2.0(b20/vtec possibly)


Tial 40mm WG should do the trick for ya, i dont think you will see boost creep. Talk to Vapor about manifolds. and for BOV...go with a 1G DSM bov, a nice quiet, recirculated BOV..but your still going to hear it.

now realisticly...keep your goals low...if this is to be a daily driver, i wouldnt look any higher then the 425whp range.
