Piston rings fried - stillen supercharger

nvdave04

Thank you all for the input. What's crazy is i should have known something was up when my local tuner told me he had to stop tuning at only 379 whp at 10psi!! This was on the heart breaker dyno. He said that my GTR injectors were at 99% and MAF were almost at max voltage! I thought that was insane at less than 400 whp. Also like someone else's said it was cylinder #2 that gave. I bought the kit used with the upgraded impeller man I wish I could take that out! Now the decision what to do next.

The person who works on my car works for nissan so this plays into my decision on which route to go. I don't plan on selling stillen kit due to the hassle and good deal I got on it so going TT not a option. But Damn I wish some vendor would make a kit I can buy to move the MAF sensors ugh !

Scenario #1 - short block - since he would have to tear motor apart and would take some time he would have to do this at dealership and charge me a reduced labor price and also risk finding a ****** up head and than have to build that. I was also told by IPP that I won't get the benefit of the porting if you did keep you stock heads.

Scenario #2 - used motor swap- this is cheapest option - if I did a complete engine swap my guy who works at the dealership can do this at his home shop on a weekend and not charge me any labor to do it. He's a great friend I know lol - but my concern about buying a used motor is I feel like it would just be a bandaid fix and kinda just wasting $2000 with no performance benefits and the risk of this happening again and not to mention no way to really know how many miles are on the used motor and how it was treated.

Scenario #3- built stage 1 long block from IPP- most expensive option but most positive gains and if I did this I would keep this z until the wheels fall off no new car for me for a long long time lol - my guy would also be able to to the swap at his house and not charge me any labor and said he could have it done on a weekend. Only downside is I will have this awesome built long block but still have stillen kit and never get use the full potential of built motor kinda like overkill. But I should have piece of mind with this built motor and not be in this situation again. I don't think I would see any performance gains from built long block right just a safer more reliable motor right ?

Scenario #4- sell car as Is - cut ties and loses - what do think I could sell for ? I still owe 19k on loan

Injector duty at 99% is way too high, you can't even account for variances in temperature at that point. No wonder the engine ran too lean.
