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.
