i was running a t50 on my gze turbo it pop with 200hsp after a year, one day after 1000kg clutch and lighten fly wheel was instilled. it went half way through second at 12psi sounds of metal every where. looking at a new w58 from japan or a bullshit gearset or trusting china on the copy.
ive been reading a lot of stuff its a custom tail shaft behind w5* and should do the diff upgrade if aus speck T or bigger
