Stuffed 1Jz turbo's Wed, 11 September 2002 11:35 Go to previous message
Had an unfortunate incident on the weekend. I was driving my Supra MK2 with 1JZ engine and factory CT12A turbo's. Just recently fitted a large intercooler so it was going very hard that night. Max boost was 15psi like it has been for a long time. Anyway the box changed from 1st to 2nd and when it was in 2nd I accelerated. At this moment I heard a bang and then a loud whine and no boost.

I limped the car home and took the inlet piping off and found the front turbo was wrecked. The compressor wheel was hitting the housing and lost most of its fins. But the exhaust wheel was intact with no damage. Same with the rear. The compressor wheel had been hitting the housing and exhaust wheel intact.

Now what the hell could have happened? It's running the factory ECU and has twin dump pipes of each turbo. I know that the car was running rich from the black smoke. Could a backfire have caused the shafts to bend and the compressor wheels touch the housing?
