Hi
What are the upgrades available in the aftermarket for this engines??
I need order part car Fuel Injection pump for Nissan Terrano, do you have on your stock
Great.thnk you. I have a question though, re rpm. W power steering,850rpm. if auto transmission, what is d required rpm?
I need the crankshaft tightening procedure
What is d rpm required for td27 (nissan caravan 1993 japan) w power steering, auto transmissionwhen aircon off? w aircon on?
