i have a 90 240 sr20det. the motor has 36000 . under load, when the turbo spools good it smokes bad.deep black smoke. but since the motor has such lil miles it would of have been fucked every day for the valve stem seals or piston rings to be bad right? im hoping it is the turbo crapping out. i have a t28 ball bearing, not the t25 on the stock sr.
