TOMEI 2.2L Used for Over 10 Years, Trouble Free!

Drag racing used to be really popular in Japan a long time ago. I have been using Tomei Pistons since way back in those days. After all these years and the countless of abused performance engines I have disassembled. I have found that the engines that were running Tomei Pistons are always still clean and problem free. I personally have been the Tomei 2.2L kit since it was released over 10 years ago. Still to this day I've never had any problems with mine.

The 4G63 engine design suits high engine speeds but lacks torque. The Tomei 2.2L changes the engines characteristics to an engine with loads of torque and makes it very durable. After upgrading to the Tomei stroker kit, our options on which size turbos we can use was much larger.

We can use any larger turbos on the engine now without concerns. The stock engine has weak Conrods and pistons, so this was always the limiting factor before. But the Tomei stroker kit eliminates those weak points. So now we have much more freedom to do what we want with the car. Another one of our customers has been using his Tomei 2.2L built engine for over 10 years now without any rebuilds and has never had any issues with it. Why don't you try a Tomei 2.2L kit for your 4G63?
