Well after a year of boosting a stock z6 motor on 10 pounds my friends motor starting knocking real bad the night before we wanted to go to the track. So in a desperate attempt to get it running again quickly before we went to the track the next day i let him have a stock d15 bottom end i had laying in the garage. After a trip to the parts store for a headgasket and oil we put his z6 head on the d15 and had it in the car and running in about 5 hours. Well we let the car idle for a while so it would warm up hopped in set the boost down to 6 psi and went for a test drive. The car was running well, went to the gas station and back to the house which is about 3 miles. Then my friend decides to turn the boost to 9 psi and go for a drive. We got 2 good pulls in on 9 psi and on the 3rd one this happend



Well atleast it went out in a good bang! Now its time to tear it all down and do it again

breaking rods doesnt really have anything to do with a tune...

It had his tune on it form his d16z6 which he ran the **** out of for right at a year. Everyday at that. I think the allmost 200 thousand miles on that weak *** bottomend is more to blame.

Yep! 1 and 2 went through the block and 3 went through the oil pan. Im hopping when we go to take it apart # 4 is broke > Never seen that before

you can destroy rods with a bad tune but I dont think thats the problem here
