The S-trim is a polished unit that just had both seals changed by Jim Mills Racing. It's in perfect working order. It has the usual scratches from removal and installation. The bearings were inspected during seal change. The unit has about 6,000 miles on it. First $600.00 + shipping and pay pal fees firm gets it. I will also throw in a 6 rib 3.3 pulley with the head unit. The only reason I'm selling is because I'm going a different route on my new build...I have Pics if you're interested.....Note: This is just for the head unit only! I also have a non intercooled discharge pipe, a 90mm Lighning MAF meter, and a brand new 6 rib Idler pulley that you will definately need for installation. These parts will be extra thanks...
