Ok guys this is the details i gathered of the turbo, so i finally know what turbo i have now and what i can push it to.
Compressor housing:
Garret A/R60 m24 1-2
Exhaust housing:
Garret 0.64
Badge:
DI 0334J
1441-G1f00
466541-4
The turbo is know as the GT2560R-4 (aka gt28r) which can take upto 330hp and has a max efficiency rating at around 14-16psi depending on the setup. It has a really quick spool and its nice but it just lacks alot in the top end.
