    It kinda depends on a few other things. What turbo, what boost, etc. A 38mm on a GT35r trying to only run like 8psi is prob going to creep. But I have seen 38mm hold 28psi on a 650whp Honda.

    probably going with gt35r or gt3071r on an SR20, looking for a shade over 400 rwhp. I have a brand new 38 mm TiAl, just trying to figure out if I should go ahead and get a 44 mm
