Best factory motor for boost
Just pulled the motor and figured out why it let go. The guy I paid to put the turbo on the car hooked the boost source up on the wrong spot on the wastegate. He hooked it up to the top port so instead of spring pressure (8psi) it just kept building boost until the motor let go.

Otherwise the overboost problem would...should have been spotted a long time ago.
And doing a burnout in an un-tuned, untested, newly turbod build...seems a little odd.
So you're saying this burnout when the engine failed, was the very first time the engine was run hard since it was built and turbocharged ?

The tune is safe more than safe for boost up to 3 bars. I already had the car fully tuned N/A. Once you have that, it's pretty easy to get a base tune for boost. Timing was at 10* like I said which is very conservative. I set fuel the way I was taught (ddouble the amount at 1 bar verse atmosphere). I then added a little fuel on top of it to be even more safe. The only thing in the equation that was off was boost which if that guy did his job correctly would not have been a problem. If boost was good nothing would've ever happened.

So you did drive an untuned, untested car at high load.
If the tuner had done their job correctly, no damage could ever have occurred. You do realise there is more involved with tuning that sitting guessing numbers on a keyboard then hoping for the best ?
If this is how you tune, you really should take the car somewhere professional, at least that way you will blow less shut up.

I tripled the numbers at 3bar and added a little.
The method works as a baseline.
The boost likely went through the roof.
Lessons learned right?
Always check others work.
Data log the car every time.
The factory ECU cuts fuel on the limiter.
I've bounced off mine numerous times at 7200.
SBE L33. No issues.
The factory ECU isn't fancy, but they are very capable.

10 LS Engine Myths That Refuse to Die
Verdad Gallardo Plain and simple, the boost is what blew the motor. When I pay a business almost $2,000 to do a job, I expect them to do their job correctly (hooking up the wastegate was part of his job). Had it been done correctly my Motor would still be in the car right now. Nobody can dispute that. You don't like my opinion that somebody should've done their job correctly then that's your choice.
This is the last I'm talking about this. I made the thread for opinions on Motor choice, not on what happened to mine or who was at fault. A couple people asked for me to let them know what happened so I did.

You started hammering on something on an "I guessed on the numbers" tune. If you had any idea what you were doing, the datalog would have been running and this wouldn't have happened, or at least you would know the exact AFR, timing, and boost when it blew.
Also, OEM cars running 9:1 from the factory? Definitely not.
A tuner would have caught the wastegate not opening. Just saying. Sucks that your motor blew but it should have been tuned before driven at most, onto a trailer, to get to the tuner. I say it's both of y'alls fault.

But to answer the question, gen 4 4.8's and 5.3's seem to be the hot ticket. Not a lot of 6.0 builds around these days.
