Mish forged pistons beyond that don't know much as I bought the engine as is...
Injectors, Bigger Turb and Actuator are the plan at the moment.
Traction control is through the Adaptronic computer, there is a wheel speed sensor or D/S Rear and P/S Front, and you adjust the % amount of slip, its all hooked up but I have yet to tune the traction and launch... want to get it rego'd and on the road before I really try to break it... plus I have to swap the diff centre over from the locker I have in there to the LSD centre so its a little more forgiving on the axles etc... lets see if it lasts, meant to be good for 250hp.
