there have been decent power gains on the 8 as well if set up properly. Al still seems to like it as well... it might not be as nice as the 9 but i made decent power off it and didnt surge all that much for me.

i will say this for the last time as this has GOT to be the definitive thread, even tho the poster went off topic in his own thread.
the difference between the 8 and 9 turbo.
both have 10.5 hot side. both have unaltered turbine wheels. both use the same chra, this means you can swap and mix and match these two turbo's parts to your heart's content (tme9 plug inserted here).
the cold side is the only difference. cold side housing has a larger diffuser, this is the snail section, it's both longer and wider in diameter inside, this creates a faster boost up/boost production/boost response. as a result of the added length of the snail section also known as diffuser, the overall housing is larger. the exducer of the 9 turbo is larger to fill up the space inside of the 9 housing (see below for caveats). the inducer remains relatively the same size.
the reason for br moving to 9 housing is to remove all chances of surge on his and now fp's wheel, larger housing also allows more air through even though the wheel that the 20gs are using is based off the old 8 housing which would leave exducer diameters smaller!
small things that are different. the angling of the turbo oil lines is slightly off due to the 9 housing size. the angle of the coolant line is also a bit off. these two can be bent to fit. the cold side outlet pipe is much different and you can't bend this unit to fit it between the two turbos.
