RR Racing Makes History, Again!

The IS250 is finally gets its long-overdue power with our release of the supercharger kit for Lexus IS250. With our Stage 2 pulley and optional ethanol or methanol add-ons, IS250 makes a whooping 370 wheel horsepower more than doubling the stock engine power!

Honestly, we did not think that IS250 is capable of making so much power. However, with some smart engineering and tuning and with an addition of a simple single fuel injector to add fuel, the results are simply astounding.

Even compared to the Porsche 991 Carrera S the new IS250 does not fall short.
