I have a B1-2 turbo and down pipe in great shape with normal side to side play and no in and out. There is nothing wrong with turbo at all!!!! Took the truck back to stock to sell and thats it. It does have a wast-gate on it set to about 41 to 42 psi. The specs are I think 62mm inducer...as far as turbine specs...not exactly sure but TAD keeps that info to himself but I'll guess 65mm wheel, .8A/R housing and it spools great with a comp box and Mach 4.5 and with DD3's $1000.00 or best offer
