This is a brand new .48 AR turbine housing that is a direct replacement for Garrett T3/T4 turbos. The housing does say AiResearch on it but it is in fact a replacement part for Garrett housings. It is a T3 flanged, 4 bolt exhaust housing with 2.5" outlet. If you want a quicker spooling turbo than just simply unbolt six bolts, carefully pull the housing off and replace it with this unit. I bought this in 2005 and just never used it. The receipt shows original price of just the housing (but for some reason it says .63 AR on it). Bought directly from a Garrett dealer. There's a little bit of surface rust on the flange but it will be cleaned off prior to shipping. Asking $100+shipping or best offer.
