730HP 2JZ and 8 gears the perfect combination of pure JDM goodness with a dab of German refinement! 🇯🇵⚡
We’ve just finished off the final touches on Chris’s Toyota JZX 100 Chaser, and this thing is a weapon. The highlight of this build is the ZF 8HP 8-speed gearbox conversion, a setup that completely transforms the JZX100 platform with lightning-fast shifts and modern driveability.
An Upgrade in ECU was required so we wired in a Elite 2500 ECU alongside a dedicated Transmission ECU to handle the 8-speed’s logic. We also converted the car to Drive by Wire (DBW), allowing for precise throttle blips and seamless integration between the engine and the new gearbox.
After bolting it to the dyno, we dialed it into a stout 730HP at the hubs. Setting up shift cuts while banging through the gears on the Dyno is something else, the power delivery is relentless, and it stays In boost through every single shift. It’s the perfect blend of classic JDM style and performance with 21st century drivetrain technology. With 8th gear allowing great fuel economy on long trips this combo really is the best of all worlds
Huge thanks to Chris for letting us take this build to the next level. We can’t wait to see this thing out on the street!
