Yeah hahn 8 psi my ass. heh. I have been running 6 psi since i installed the kit. Its stage2 with fmic. I just turned it up to 8 and kill my engine. Im not too upset, this just means it time to throw in the rebuilt motor. I was not leaning out or anything. This sucks. Ill post the damage photos when i can! looks like im going to be taking the bus to work for a while now.. hah!

how many miles you have on your car and how many miles have you put on since being turbo

Been turboed since december. Car had 55000 before turbo and 4500 turbo miles. My compression was 120 acrost. time to swap in the rebuilt engine, then rebuild this one. shit.

was that 120 before the turbo or after it blew up.

did u upgrade the injectors?

120 across is REALLY low. Sounds like the engine already had some problems before you turboed.

120 across?

That almost more akin to a bad HG. Did you have some overheating issues?

Did you have an EGT gauge?

yeah, if it was 120 after then you might've just blown your hg. i think that's actually what happened to dave_fl. thought he blew his engine, took it apart and it was just the hg. rebuilt anyway though.

yeah it was 120 before the boom. Im going to put in my rebuilt 420a now. its 25 over with je pistons 8:1 and eagle rods, oversized valves, blah blah. it should be a strong motor.

heh, if you're putting in that beast, sounds like this little 'accident' was a blessing in disguise...

Yep! hah. It just sucks driving a 92 crown vic when its finally getting warm again!

Your story has inspired me to drive my car like an old woman. Thanks a lot.

well i wouldn't take it back to that mech that you brought it too in the first place because if he couldn't tell that the comp was low when he did it the first time then IMO he doesn't know his head from his ass...... cause any good mech would have told you that there was something wrong when he did the comp test...:nono

yeah do that and you will always have a dsm in your garage! ever wonder why the old ladys always have a 74 buick that STILL RUNS! heh

just checked it. ~ 190-60-190-190 errrrrr.

2 problems here. cyl 2 is jacked up and my mechanic is an idiot.

try a leakdown test.

Cylinder #2 at 60 psi? Sounds like the famous cracked piston ring land :o I'd doubt its your HG. Blown HG's are just not a comnon as people think, esp when turboed, althogh its always a possibility, I just dont think so. You would have nasty looking oil, and prob frothy coolant. Pull the oil dipstick when the car is idleing, and if you can feel/see any puffs of vapor coming out, then its a piston ring land for sure. You will notice about 1-2 Hg's less in vacuum also.

on supras you turn the boost up past 11.5 psi and the stock headfasket goes by by (mkiii supras) i gotta get a hks metal one before i do jack to mine, so bhg's happen, just not as much for these
