 Keep posting the results. Having modded a GA16 to moderate turbo power levels I am curious as to where you wind up. FWIW the revised OEM GA16DE headgasket held 18PSI and 270+ WHP without issue, is the QG gasket that much worse?

With the cylinder head and valvetrain remaining stock I am targetting 300+ whp. Headgasket is the Ajusa MLS unit. Latest updates up on my blog.

Sorry Sergio. There is barely any room left in between the cylinders for overboring. You can prob'l safely go up to 0.5mm overbore max.
