Nissan is mainly known for the exceptional inline-6 RB26 engine in its Skyline GT-R sports cars. However, for the majority of enthusiasts out there — particularly those with tighter budgets, the SE20DET is the preferred choice. It is a compact, lightweight, all-aluminum, turbocharged four-cylinder engine from the Silvia that could fit most project cars. Moreover, the 2.0-liter capacity and sound construction mean solid tuning potential. Simple upgrades, like a new turbo, intercooler, intake, cams, or injectors, could bring it close to 400 hp.
From the factory, the SR20DET produces up to 247 hp in the most advanced S15 Black Top version. Meanwhile, earlier versions pump up 205 hp. The upgrades in the newer versions are mainly new ECUs, improved turbochargers, new injectors, and cam profiles. However, the aftermarket support is booming, so you can easily make the upgrades yourself. The SR20DET naturally fits RWD cars, which, along with the compact dimensions and low weight, made it a darling in the RWD drifting community. However, with certain modifications, Nissan’s most popular four-cylinder can also fit FWD and AWD projects.
Due to its popularity, Nissan’s SR20DET family of engines isn’t as cheap as it used to be. Still, prices vary wildly and depend greatly on the engine’s condition and completeness. You can snatch one for $3,000, with good-condition units costing upward of $5,000. Meanwhile, fully restored “like new” and tuned SR20DET engines that don’t require further modifications cost north of $10,000. Considering the excellent tuning potential of the SR20DET, those prices seem like a bargain.
