Following the CA18 engine, the 4 cylinder SR20DET was first introduced in 1991 and has been the mainstay of the engines produced by Nissan even until this day. The aluminum block design enabled the engine to be lightweight, continuing to be produced for 12 years until August of 2002. The final edition of the SR20DET can be found in the final production era of the S15 Silvia.

incorporated within.

SR20DET in the US

The United States industry currently is focused on such motor sports as time attack circuit racing, drag racing and drifting. Here, the Nissan 240SX can be seen as a competitive platform, with the enthusiasts discarding the original KA24DE for the more powerful Japanese spec SR20DET unit. However, the drawback was that these engines were not produced and equipped in the US spec 240SX so the enthusiasts were left to import the engines and perform a transplant. Currently in the US, and also in Japan, the SR20DET is becoming scarce mainly because the popularity of this chassis in the sport of drifting. It is common to hear about the dedicated Nissan enthusiasts going through great lengths to get the engine to the US and find out later that the unit is problematic. It is also widely known that most of the American tuning shops are also left to work with used components when exchanging cylinder heads and blocks because they have no source of a new component.

CONDITIONS OF AN USED SR20DET

The majority of these engines have suffered a great deal of wear and tear, frictional loss, and abrasions. The areas most often affected are the inner side of the cylinders, pistons, bearings, main journals, valves, valve guides, and seat rings. The SR20DET users acknowledge these problematic aspects, however it is recommended to further consider the fact that the performance of these worn down engines greatly differ and begin to deteriorate with every use.

NEW S15 SR20DET ENGINE BENEFITS

Although it may only be around for a short period of time, there are ways to obtain a new SR20DET engine. The tuners and race teams that are serious about winning and cannot risk using worn down components can now acquire a new long block to build an efficient and reliable full race engine. The final edition of the SR20DET, which has gone through 5 variations, is the best SR20 unit money can buy.
