37R W/stock internals
I have a 37r I'm getting ready to install. I have HKS 272's, water meth and plenty of fuel. How much boost is ok on stock internals? Need some help.

Whatever, I ran 32psi for 30K miles daily driven 45 mins one way to work. Over a year. Youll be ok.

Its all in the TUNE

Detonation at high RPM's is what kills. If you can get a very reliable tuner go for 30-32psi.

dude all you need is head studs and a good tune...over 25psi without head studs is sketchy...but the rest is based on the tune if your tuned good theres no risk...minus your meth malfunctioning

What is the point? You have a laggy turbo with a low rpm ceiling due to the stock motor = ****ty powerband. You are not going to enjoy it.

here's a thread with lots of dyno sheets with all stock blocks, some builds have head work but 90% of them have/had 100% stock bottom end
