Prior to, a brand new USDM ITR transmission was ordered. Aside from the 4th, 5th and final gear, it is completely identical to the JDM 98-spec trans. Listed here are the gear ratios for both trans.
USDM ITR transmission gear ratio:
Final Drive: 4.400
JDM 98-spec ITR transmission gear ratio:
Final Drive: 4.785
Having the closer 4th and 5th gear was defiantly a plus, however the potential was limited by the 4.400 final gear found in the USDM trans. Solution? That was easy, we replaced it with a 4.929 final gear from ATS&ACROSS. Increased acceleration and response is noticed from this new setup.
New transmission with ATS&ACROSS 4.929 final gear @ 9000rpm:
1st: 3.230 – 63.47Km/h
2nd: 2.105 – 97.38Km/h
3rd: 1.458 – 140.61Km/h
4th: 1.107 – 185.19Km/h
5th: 0.848 – 241.74Km/h
Final Drive: 4.929
