As some of you may have noticed, I have been spending a lot more time lately focusing on the drivetrain end of things. I am about to embark on a mission of creating the Uber-transmission (ultimate transmission).
Traditionally, the Uber L3 transmission has been a combination of ZC 1-4 gears, Si or HF 5th, and the final 4.437 drive from a JDM Integra ZXi.
I want to go one step beyond that with the transmission that I am about to build. I am planning on using ZC 1-4, an HF 5th, an SRR 4.9 Final drive and a Quaife ATB differential.
The 4.9 final drive should make the gears 1 - 4 25% shorter than if I were driving with a ZC transmission with the stock 3.88 final drive. I am opting to use an HF 5th gear because it should keep the RPM's about the same as if I were using an ordinary Si 5th with an Si final drive. I don't want to sacrifice my highway fuel economy.
Any comments/suggestions on other ideas for this project?
