New rebuild on VE+T, low compression test numbers...
I got
Cyl# PSI
  1. 165
  2. 170
  3. 164
  4. 169
This motor has about 500 miles on it and I ran Royal purple break-in oil. Its a SR16VE head and cp 87mm 9:1 SR20VE pistons, eagle rods and DE block, crank and VE oil pump and dampaner. This might be better in the VE section, but I thought I'd put it here since it is a VE+T...What kind of PSI should this motor net?

looks good to me. I only get around 145psi up here on 8.5:1. But I haven't checked this new motor.

Id say it is good.

Id say thats fine. All 4 cylinders are within 6psi of each other which is really the most important part. I only get a little bit more than that with 9.5:1 so considering your 9:1 id say your golden.

Looks like VG30DETT compression is 171psi, and 128psi being low, its also 9:1 so I think I'm golden!!
