2700 bucks for that engine is a steal.

Thanks, this is something I'll for sure look into. How long have you had yours? Are you running blower or nitrous on it?

RE: RIP stock motor. What now?
I say CP pistons. Theyre beefy as hell. Check out these pics. Ill be installing these 9cc dishs with the Modmax h beams and forged cobra crank.
For rods, Manley, Modmax or Eagle (make sureARP2000 bolts)andof course aforged Cobra crank.

RE: RIP stock motor. What now?
Well just a few days ago I finally was finished building up my motor and went to the dyno to dial it in. I just did not get the hp I expected. So I did a compression check and as I feared before it was very low average about 110psi. From what I'm reading you did the compression check in a different way and I do not know if you can read correct numbers that way. I was always the impression that you have to disconnect all sparkplugs plus the fuelpump first. Then use starter and full throttle to measure the compression. First you measure without putting oil in the cylinder. Then put some oil down the cylinder and then measure the psi again. If the psi goes up you have cylinder blow by. If the pressure remains the same you have a bad valve. I do not know about you guys but that's how I was thought. You agree? And by the way I will start rebuild my engine with forged internals this coming friday. Can't wait to finally but some big boost on the motor!

RE: RIP stock motor. What now?
Just for sh-ts and giggles, did you do a Wet compression test or a dry compression test?? The reason I ask is, even though you can't precisely diagnose a hole in the piston w/ a wet compression test, you can at least find out if it's more valve/top end related than bottom end.. Plus, I believe they have little scopes you can get to look inside.. Obviously you've got bigger problems, so maybe disassembly would be the way to go though..
Oh, and +1 on the VT Engines.. Those are pretty nasty, and I like their reputation... I'm sure the others are fine, but VT would've been my choice if I still had my car....
