This is a used T4 unit we had on TheRedDragon's car. It made 499whp on 93 octane pump gas. We were going to use it again but we decided to move to a Bullseye Power unit. It's in perfect condition. Oil was maintained. Used a -3 with a .035 restrictor. Brand new black thermal coating on the turbine housing. Asking $800.00 shipped or best offer plus shipping. Many people can vouch for this turbo or myself
