Heres the pic of cylinder 3 It seems as though I need to bore it out and put bigger pistons in. Do you guys have any recommendations on a good not super expensive piston suggestions?

how did that happen. Did you run it too lean or something. Was this on the stock turbo or upgraded turbo.

And as far as pistons. It depends what your plans are. Stock pistons are about 225 dollars for all four plus 80-90 dollars for rings. Cp pistons are what most sr guys are using and you can usually find them for about 450 and that comes with pistons and the rings together.

I have no clue how that happened all I did was add a walbro fuel pump. The guys at the Machine shop. Said it was very possible that bad vacuum could have done it and cause some type of surge on cylinder 3.
