STi motor Flat 6?? Im sure this could be done , Mad frankenstein.. But everything Crossfire will be lost. This xfire v6 motor will have NO Problems with this turbo kit installed, again Klemann has been boosting the 3.2 for Years with no issues......
I bet if you whack a sti piston or LS piston with a hammer it will shatter prob should just stick to hammer and nail combination
