The best solution in our opinion is to reuse the stock Alusil bore, retain the structural integrity of the block and run custom designed Mahle LC pistons designed for boost with OEM grade PWC and piston coating. It is an expensive solution, but the end result is an engine that runs like a stock motor with no durability compromises or excessive oil consumption/engine noise.
how long to you think it would take for the cylinder to be no good? we all dont want to leave it to late! haha and how much boost will you guys run on this motor
