i just did a 1jz-gte r154 swap into a 91 auto sc300 and i am haveing some problems. sometimes when i take the car out of any gear the clutch seems to be rub the pressure plate when the clutch pedal is depressed. it will continue until i let off the clutch in neutral. if i try to put it into another gear it "grinds" then goes into gear. it only sounds like a grind (but i dont think it is).do i need a new clutch? or throwout bearing?
