Gt45 80/75 billet wheel, triple ball bearing, t4 1.00 with 4" exit exhaust housing, 5" in 3.5" out compressor. I made 740 rwhp at 16psi on my 4.6 mustang on a on3 forward facing kit. I've got about $3,500 in it, it's a little too big for my setup is reason for selling. It would be awesome on a auto 4.6 or on a bigger motor with any trans. It might have 10 miles on it with dyno time included. Asking $2,800 Obo shipped. 3.5" to 3" coupler included (not pictured). Located in big stone gap va. You can text or call two7six-870-0two29
