I am considering purchasing an m coupe (not considering, just waiting for more money), and I want to purchase a mechtech motorsports turbo. One example has made 300 wheel horsepower and apparantly others have seen higher numbers. 300 whp was achieved at 8 psi. How much boost in psi can the 3.2L m50 take regularily before a built bottom end is necessary?

True, the aa kit is a beast, but you saw how expensive it is. The mechtech kit is 5000 dollars, as opposed to 30 000 with installation. The mechtech kit makes a heavy 300 at the wheels at 8 psi, and I need to know how high I would be able to turn up the boost without damaging or stressing the engine. If I could dial in 12+ psi I would be doing about 340-350+ horsepower at the wheels without additional mods (or few). I just don't know if the stock bottom end can hanbdle it. Anyone else got a clue?
