.....Well the bad luck began, my hood flew open on hwy 10 going about 70mph and fold backwards cracking my windshield and denting my roof, alright that sucked ass. So I ziptied it back shut and did not have any more problems with it.
Don't feel bad.... you surely are not the only one that has done this lately......:mad:
I highly doubt it had anything to do with tunning.................. either a oiling or bearing setup issue....... that is i am assuming the noise you are hearing is a spun bearing

Uhm, what fuel were you running? Timing? Sucks man. Good luck with rebuild.
A mix between 92 octane and 110.

I will know for sure in the next few days when I tear it apart for replacement of a few key parts. -

AFR leaner than 12:1 or so will certainly damage your motor, ESPECIALLY if you're not on race gas. What do most people tune their turbo motors to on race gas, about 12.5:1 at most?I think your information is off just a bit. I generally shoot for a 13.5 afr. For a good tune.

I really do not see how I could have damaged anything with my tune. Considering I did not go into positive boost territory beyond 8psi max as that is what my wastegate is set to. And I was on the break in cycle so I really did not want boost affecting the piston ring seals.

I don't think it was cause by me running lean or detonation. But we will see once I pull it apart if a piston is fucked I will eat my words. -

Carnage pictures this is what I found in rod #3




If I would have had fair warning the guy I got the block from was incompetent in putting together an engine I would have had the crank cut and smoothed out.
When I first popped the rod cap off it looked like there was no bearing at all and that thin pieces were what I managed to scrape off with a screwdriver.
