i have two t3 turbos what come off a chrysler the flanges have been professionally machined to fit the traditional t3 manifold bolt pattern and not the chrysler one i actually used one on my b16a2 booted just fine nice spool up and strong actually i used both before i bought my new t3/t4 they did both blow some oil out the exaust i would recommend a rebuild. I was told that it was the thrust bearings and seals that need to be replaced. so the equation goes like this t3 from me $80 + rebuild 150-200 depending where you go i would take it to texas rebuild thier good and in the end you have a perfectly functional turbo for 230-280 i decided to fork over the extra cash cause I had it.
