I blew up the turbo in my '03 SO. I was running a TST, 4" exhaust, and afe. I was towing 10,000lbs (two competition rock buggies) when the turbo barfed it's guts into the motor.
DC denied my warranty, because they believed there was an aftermarket box on the truck due to engine codes in the PCM. After lots of phone calls, meetings with attorneys, and being hung up on by the area rep (a real tool, I might add) the only way to get anything done would have been to sue them. I decided to suck it up and fix it myself... I sure wasn't going to pay the $13,000 the dealer wanted to fix it! :--)
I got the truck home, and have it apart. The only visible damage is the fragged turbo, a contaminated intercooler, and bent valves. There are turbo chunks sitting on top of the #6 piston, but no visible damage to the cylinder(s) or piston(s). The head is at the machine shop being checked for other damage...
Questions:
1) Is there a way to o-ring this head?
2) What is the max boost this head/gasket can handle without being o-ringed, reliably?
3) What is the best single turbo for 400-500hp? I need it to be RELIABLE, as we tow fairly large loads across country often. Where can I get said turbo?
4) Where is a good source for intercoolers? Are there any better aftermarket intercoolers I should be looking at?
5) Are there any good aftermarket cams for this motor that make good reliable power?
