I know the car. It is a genuine XR6T engine conversion, however.... It still has the single spinner XT diff. Still has standard ECU, with a seperate boost controller, therefore it's hard to adjust fuel and ignition settings. It's had a fairly hard life, and the diff it clunking. I would factor at least $4k on top of the price to have a peice of mind it will stay together. which almost takes you to the Xr6T standard price anyway :(
