Got a Holset HX35W with the 12^ housing. been sitting in my shop for some time now along with 3 others, im selling to fund a Borg Warner S366. Id like to get $350 for it. It should support about 480-520ish hp. On my B20, it was building 18psi by 4500rpm. Comes with the factory Dodge compressor elbow and exhaust flange.
