My supra had a bad time last night.
-
Last night I decided I would take my supra from St.Cloud up to swanville at night and do some street tuning on my way to my roommates parents place.....
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.
So just before elmsdale I hear a weird noise coming from me engine so I pull over in elmsdale and get out of the car to hear the engine closer... sure as shit it is knocking like a mad black woman wanting her child support.
So I had a really bad time last night and will post pictures in the morning.
The good news is I will rebuild this next week and be good to go. Since my roommate picked me up with a trailer (thank god and at 3am even what a nice guy). But where the car sits now in swanville there is a 4 post lift and plenty of tools for auto body working to fix my roof and pull my engine and replace it right here.

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.
