Following up the release of their popular Mitsubishi Lancer Evo 4G63 bolt-on turbocharger, Tomei has announced their SR20DET bolt-on turbochargers, both priced with a MSRP of $1,390.00.
Designed to replace the Nissan rear-wheel drive SR20DET-powered 180SX and Silvia engines’ T25/T28 turbos, the Tomei ARMS M7960 and M8270 turbos come with all the piping, gaskets, fittings, lines, and hardware necessary for a direct bolt on installation.
The unit is not a direct factory bolt on replacement for transverse SR20DET Pulsar owners, although custom plumbing could make the turbo fit.
Factory and factory replacement intercoolers, intakes, and downpipes can be used to keep costs low and stealthy engine bays intact. Like the stock turbo, the Tomei units use internal wastegates.
The smaller Tomei ARMS M7960 turbo is designed for quick response, capable of producing about 400hp with max boost around 4,000rpm. The power band for this turbo is designed around low and mid-range torque and will beat the larger M8270 turbo up until 4,500rpm.
On Tomei’s test 2.2-liter S15, equipped with cams, ECU, exhaust manifold and test pipe, the M7960 made just over 395hp (400ps) and 360 lb/ft of torque (49.9kg/m). If you’re building a usable street 240SX and will be using a stock SR20DET, this is the turbo is get.

The M8270 turbo is designed for top-end power and will push over 450hp with full boost around 4,500rpm. On Tomei’s test 2.2-liter S15, equipped with cams, ECU, exhaust manifold and test pipe, the M8270 made 453hp (460ps) and 386 lb/ft of torque (53.3kg/m).

For those that are looking for big power or have built engines, this is the turbo that will deliver 500hp without the need for custom exhaust manifolds, intercooler piping, intakes, or downpipes.
Like with all Tomei ARMS turbos, replacement parts are available from Tomei.
