S13 SR20DET BLACK TOP with TOMEI ARMS 7960 TURBO.

Here is another SR20 engine with TOMEI turbo.

This car has 140,000km stock engine, bit risky? but let's try.

Again Tomei bolt on turbo with Poncam, injector and pump.

And here is the result, normally stock T25 turbo will make 180~190kw at wheel at 1.2 bar of boost.

With this set up, almost 100hp at engine gain.

around 380~400HP at engine.

Here is the another option.
