look for the A/R numbers on the housings, if its a t34 of some discription
it should have .48 somewere on the compressor housing and .48 or .55 or .63
in or on the exhaust housing.........it deffently DOES NOT look like any
turbocharger ive seen off a standard YB engine.

if it is a t34 or t3/4 turbo it will be fine for up to a stage 3 application

hope this helps mate
