Default So my friend blew up his WRX

Well, my friend took his 2004 WRX to the track on Sunday. The car has STi pinks, STi TMIC, 3" turbo back, perrin short ram, and a UTEC. At the end of his third pass, he said he was shifting into fourth and and the car "dove" when he let in the clutch. He put the clutch back in, shifted into 5th, and drove back to the staging area. A short while later he started his car to make another pass and the car was making a clunking noise inside the engine on the passenger side while idling. When it was turned off, the engine continued clunking while it was winding down. It clunked 3 or 4 times after the ignition was killed. We called a tow truck, and the car is currently sitting in my driveway.

From what I can tell, the reason the car "dove" is because he shifted into second and not fourth at 90 mph, redlining the engine.

Any ideas on what could have broken inside the engine?

Probably everything. If he did shift into 2nd instead of 4th after redlining 3rd then he basically overspun the entire engine assembly. Did he say if he noticed the rpm needle just rocket up after the shift to 4th or if he really did indeed put it into 4th and the engine just blew?

Umm, ya... the electronic revlimiter isn't going to save you from overreving the engine by shifting into a lower gear then the current one after redlining the current gear.

Yea if the car went into a dive he probably missed a gear and sank the needle in the tach.

could be bearing or busted rod as well but not necessarily. REv limiter wont do crap whn rolling and the road speed is barrelling up the gearbox and getting reverse multiplied so your engine goes mental. In my 2wd its easier to get away with as overrevving from average changes most times itll just compression lockup but in 4wd the wheels aint gonna slide so something will go bang. BANGBANGBANG.
ONly one way your friends going to find out whats broken. ooh the anticipation.
I hate breaking stuff now.

From what you are saying about 'side of the engine etc...
I would say if it has indeed had a big gutfull of revs that the cambelt may have spun a tooth or 6 and that may be the clunking. Failing that I would say you have spun a bearing or worse. I have seen a EJ20E spin to 9800rpm on a 'driver error'!! spun the cambelt a few teeth and bent 4 valves, other than that-FINE! I fitted later model cambelt covers with the belt guides and never had another problem!

Cheers

The engine is coming out Thursday. What really concerned me was the fact the engine continued to make the noise after it was shut down. I am hoping for something minor like a rod or main bearing, but I am beginning to think something is screwed up in the head as well. I imagine the noise would have stopped after the engine was shut down if it was a rod bearing or something related to the piston ring.

I am reluctant to start the engine again, so the car needs to be pushed uphill into my garage, which is going to be loads of fun. Now I am going to have two dead '04 subies in my garage

Anybody have any suggestions on a reliable shop to send the engine to to be rebuilt?

Hmmm, I am doing some research and the ej207 doesn't sound like a bad idea. He needs to sell his UTEC, TMIC, Pinks, etc. and do the full swap. His car should be faster in the end anyway.....

Too bad he doesn't have a working ej205 to sell to help make up some of the cost.

rod knock or piston slap?? Clunk Clunk... Car dove cause you just lost power in one cylinder. That ones not creating power anymore. Its like your car turning from a 300hp machine to a 200 hp machine in one shift. The numbers are exagerated and not exact by all means, just to illustrate an example. He blew his engine at the end of third.

I say UTEC was the problem.

I'd put my money on the mis-shift being the cause for the clunking.

sucks, but do the v7. and you could get rid of that motor quickly

OK, so help me here, in the OP, you said it was a friend's car yet in this quote you are speaking of it in the possessive, as though it was actually YOUR CAR.

Utec problem being a bad tune. Now, when he shifted into fourth, did his RPM's shoot up? It wasnt said so I guess he blew his motor in third.
