The QR20DE powertrain does not represent anything outstanding. This is a conventional 2.0-liter engine with an aluminum BC and a short service life. According to the manufacturer, if you use the QR20DE unit sparingly, then its resource will reach 200 thousand kilometers. Unlike its predecessor, the SR20DE, the new QR20DE features individual ignition coils and an improved cylinder head. The IFGR system on the intake shaft was also added, and balance shafts began to be responsible for the smooth operation. Due to the lack of hydraulic lifters, it will be necessary to adjust the valve clearances every 100 thousand kilometers. Continue reading Engine Nissan QR20DE

Engine Nissan SR20DE/DET/VE/VET
The SR20DE powertrain first appeared in 1989 and received an aluminum cylinder block with dry cast iron liners. The SR20 series engines received several modifications, the most powerful of which was intended for the Nissan X-Trail GT SUV. This variant was a turbocharged version with 212-248 intake camshafts, 8.0-11.0 mm lift and 244 outlet cams and 11.3 mm lift. The reliability and durability of the 2.0 liter Nissan SR20 series engines suggests that there are no global shortcomings. Among the minor drawbacks, the floating XX (idle) and periodic breakdowns of the mass air flow sensor (mass air flow sensor) were noted. Continue reading Engine Nissan SR20DE/DET/VE/VET
Engine Nissan MR20DE/M4R
The start of engine production according to various sources dates back to 2004 or 2005 and is produced to this day. First, it was installed on the Nissan Lafesta and Nissan Serena minivans, as well as on the Nissan Bluebird Sylphy sedan (in Russia, Nissan Almera, produced at AvtoVAZ facilities).

Engine Nissan QR25DE
The QR25DE aluminum engine is rated as a weak “four”. He is a clearly pronounced “disposable” with a mileage of just over 200 with an extremely attentive and careful attitude. The QR25DE appeared by significantly expanding the piston stroke (by 20 mm) for the two-liter QR20DE with the replacement of the crankshaft and the camshaft at the outlet. Lubrication and resource depletion problems are more common here, but after 2007 the engine was modified and became much better. There are quite a few turbo whales designed for ICEs to play around with power and performance. Continue reading Engine Nissan QR25DE
