Thread: 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.

Thanks for the replys peeps...I think I'm gonna change the oil to dino and run that for anouther 2-500 miles then see how she is...

yeah they look like good numbers. non of them are really low and they are all within eachother which is most important

Unless they are all 90psi. Like me. hahahaha

yeah lol. thats really bad. but those numbers are all higher within each other which is good. so you are straight.

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

good to hear.!

my vet had 183,185,180,179

so ur close

cheers
