I took the car around the block after I changed the oil and spark plugs. It ran fine until I decided to give it a lil boost. It went up to 5psi and then the motor just stop running. I cranked the motor but it won't turn over. After about 5 mins. of trying to get the car started I decided to push the car home. Good thing this happened around the corner of the house. Got the car home and took out the plugs. Tried cranking the motor over again and still won't turn over. I grab my 1/2 in. rachet and 3/4 socket and stuck it on the crank pully bolt. Tried to turn it over by hand but it just won't turn. That's when I knew my motor was shot. What could have cause my motor to seized? Insufficient oil going to rotor bearings? Too much boost? I have no idea. If anyone knows why this would happen please help me out.

Did you try turning it backwards? Broken apex seal can stop an engine, but you can often turn them backwards, if they aren't jambed too solid.

pull your plugs out and see if those are still intact

lack of tuning caused your engine to seize.

Your sig doesn't say anything about your fuel system and ecu?

that doesnt make sense, even if he detonated and destroyed an apex seal, it would still spin, it just wouldnt make compression, unless it was stuck like what trochoid said.

That sucks. I'm sorry to hear that.

Home made boost controller? Time for a rebuild, which means time for upgrading, which means time for big porting...

Make sure the sump plug didn't fall out. Its possible...

i am running a walbro 255 fuel pump and stock s4 TII ecu w/ RB FCD. I tried turning the motor the other way and still wouldn't move.

Did the wheels lockup when it quit running? How high in the reves did you have it.

Stock clutch?


Possible that the clutch came apart and has it stuck.


Just a WAG.

I won't know until I take the motor out. I was in 2nd gear at about 3K rpm when the motor stop running. Tires locked up and it stoped running. The clutch was acting kinda strange before it happened. I might drop the tranny later on tonight just for the hell of it. I'll keep you guys posted.

Wedge the clutch pedal in with a 2x4 or something, then try turning the motor over again and see if it acts any differently...

good point. its possible he threw to much boost at a used engine and seized a bearing somehow. mabey it was just the engines time to die. noone will know till you crack that thing open.
