I've decised to run the Sc61 on my B16/B20 setup. I know the block needs to be resleeved to run the high boost I'll need to reach my goal of 500+ whp. I wanna run the T4 houseing and the T3 compressor but I need to know what AR would be best for this setup.

Thanks
Josh

 

call Precision turbo or Im Arturbo from this board. Both will be very helpful!

i talked to patrick at PT and he was such a great help

 

i would stick wit hthe t3 housing

Its good around 640hp per jim at preicsion and thats what he reccommend for a 2.1 liter setup
