Gt2871r

[jason_33]

hi i was wondering if anyone out there could maybe help with pointing me in the right direction here i have a garret gt2871r 56 trim 71mm compressor housing with the nissan rear housing making alright power 250awkw but only hitting 15psi at around 4500rpm with as much gain on an eboost2, has plenty of preload on the wastegate but should be reaching full boost alot earlier any ideas?

The ones we high flowed with hits full boost at 3000RPM. What sort of Rear housing are you useing? Also check wastegate to make sure its 100% shut with slight preload.

thats right if it has the 0.86 rear but about 1500rpm too late if its the 0.64 rear.... wait is this on a rb25? if so something is well amiss. actuator tension?
