its got 30k on the build. there is not enought traction under 65mph to transfer as much torque, its a sleeper, 2wd on stock tires. I do not know if they did anything with the pistons so I would rather not say they where reworked
I posted that to a guy that is no expert as example of this type build, it shares a lot of the same components and there is a write up overview on it. he has pistons and different turbo obviously.
