1jz R154 Transmission Specifications.

Hi. Some of my friends complaining about this blog since it is not being updated. So this post is just to make they happy and shut up their mouth. I just would like to share about my transmission.

Below are the specification about R154 5-Speed Manual Transmission:

Gear /Ratio /Km Per 1000rpm
First /3.251 /9.6
Second /1.955 /16.0
Third /1.310 /24.0
Fourth /1.000 /31.4
Fifth /0.753 /41.7
Reverse /3.18

Final Drive 3.727 (Mechanical LSD)

This gearbox has some weak points and cannot be used with high power application. In a perfect world the ideal solution is to replace the R154 with a V16x gearbox from a Mk4 Supra. These are much stronger and more widely proven behind big-horsepower 2JZ engine combinations.

If anyone have V16x gearbox please me know ya!...
