I have a mustang cobra that i'm swapping an LS2 swap into... and this is the turbo that i ran for all of 500-800mi. I never ran it above the waste gate springs... 14lbs. It is in EXCELLENT condition. I never ran it without the filter on it. I'm going bigger with the new build, so i guess its time to part with this one. Its a hybrid turbo, a precision pt88 backhousing with the 88mm turbine wheel... with 4in V-band flange, but i special ordered this unit with the optional garrett compressor housing and 91mm compressor wheel upgrade... the compressor housing has a 5in inlet and 3.5in outlet! This **** moves some air! I'm sure it would make over 1000whp with ease. This is also a t4 flange, for quicker spooling. I paid $2150 plus shipping for this turbo, and waited 4 months to recieve it. It has barely been used. I'll take $1800 shipped, or best REASONABLE, realistic offer.This is the baddest t4 flange'd turbo on the market, with no down time for the buyer. thanks!
