    I see the flare was ripped off. And I assume those black marks are just burned tire. How badly damaged is Petri's E30? Both of these car are amazing.

    It is too bad about your car. I guess it is time for another upgrade.

        It will buff out :D The tire just lost the whole thread section and it flapped against car. Destroying the flare and made the black marks.

          Well. Spoiler alert!

          I already pulled the engine:


          And tore down the engine. Number 1 and 5 pistons had cracked ringlands. No signs of piston rings binding so rising the boost at max torque point was what killed the engine. Too much cylinder pressure for the stock pistons. The stock pistons seem to handle about 600nm of torque. The 1.1-1.2bar of boost is 700nm or more which was too much.


          Otherwise engine was mostly ok. No scratches on the bores and bearings looked normal. Only few had marks of some piston fragments going through the bearings.


          Should be easy rebuild and I have already started gathering parts, now that I know what I need to get.

            10.8 is good numbers, unfortunate about your engine but I guess it's a good excuse to rebuild bigger and better
