Nissan QR20DE engine is a successor of famous SR20DE. First it was installed on Nissan X-Trail. This engine acquired new
aluminium cylinder block, new crankshaft with 80.3 mm piston stroke, and modified pistons with dome 89 mm in diameter.
QR20DE connecting rods are 153 mm long.
Cylinder head has two camshafts and continuously variable valve timing CVTC. There are no hydraulic lifters on QR20DE,
therefore every 60,000 miles of mileage (90,000 km) you need regulating valve clearance. Usually nobody does it in the old
cars, waiting for engine rattle to appear, and only then valve clearance is adjusted.
This engine is also equipped with ignition system with individual ignition coils, electronic throttle body and two balancer shafts
for the engine to work smoother and even.
In general, QR20DE is very similar to QR25DE Cyinder Head , We can supply both of them
