With all the new engine technology these days, fuel injection and making decent and clean horsepower have become an industry standard but the just like in the Hot Rod world, the art of carburetors and tuning them is a dying art. Thankfully, a long standing Japanese tuning company known more for its clutches and limited slip differentials still offers a complete engine solution for the ever popular L28 engine found in the Datsun 240Z. Using proprietary parts OS Giken has built an L28 that is tuned to output serious horsepower and offer lots of performance with a sound to die for. You better be ready to crack the wallet wide open though because it's not a cheap solution.
