{"product_id":"isr-performance-rs3871-turbo-nissan-sr20det","title":"ISR Performance RS3871 Turbo - Nissan SR20DET","description":"\u003cp\u003eOur RS3871 is a compact bolt-on upgrade turbo for the SR20DET, rated up to around 380hp. It's the budget-friendly path to real top-end power over the factory T25\/T28 without jumping into the deep end of a full custom build.\u003c\/p\u003e\u003ch3\u003eWhat It Does\u003c\/h3\u003e\u003cp\u003eReplaces the factory turbo with a larger compressor and exhaust housing for more airflow and meaningfully more top-end power. It still spools cleanly on a 1.8L to 2.2L four-cylinder, so daily drivability stays intact. The 0.64 A\/R turbine housing is the right balance for street and drift use, and the compact form factor keeps weight down compared to bigger factory-style options.\u003c\/p\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eDesigned for the Nissan SR20DET, and suitable for any 1.8L to 2.2L four-cylinder application where the flange and supporting hardware work out. \u003cstrong\u003eRequires a 3AN oil feed line.
