Ive had a engine leak for sometime now and have been trying to find the leak. But yesterday the engine felt as if it was losing power and then it just quit so i restarted it oil pressure was fine everything was except i was hearing a loud knock. then it jerk hard so i pressed in the clutch and then it died. tried to start it again and it sounded like a grinding noise. Couldnt be the starter could it. So i got it towed home and it started but was again knocking loudly and it stopped hard again but i was just idleing and the car stalled. Now all it does is grind again. If i need a new and get a 7mge will it be ok to slap the turbo on it or is that bad idea to my knowledge their specs are the same. also to my knowledge the 89+ motor only revs to 6 and my ecu is for a 87 will it still run it and the 61/2 redline hurt it. and also isnt the 89 motor a differant engine mount. any answers would be great i need this car running so i need to find something. fast.
