JDM ZC Tranny with SI 5th gear
Can it be done? What parts do I need to put in? I want this done for the highway. Simple as that. 1-4 gears I'm fine with, but I want that 5th cruising gear. The ZC tranny with the si 5th gear looks like this:
60mph - 2658rpm
90mph - 3987rpm
120mph - 5317rpm
150mph - 6646rpm
So one might ask... how does the si 5th gear extend the ZC tranny so far? Because of the ZC's final drive. This is exactly what I'm looking to do, but I just don't know what it takes to change the "5th gear"... what is required? I already have a spare si transmission for the disection.

HE'd be best to swap the Si FD and the .702 5th, depending on his setup. If boosting and keeping the close ratio ZC gearing, it would be easier to stay with the ZC/DX 3.889 FD.

Re:JDM ZC Tranny with SI 5th gear
I'm perfectly happy with the ZC tranny EXCEPT for that 5th gear. You have to understand that ALL I want to do is extend the 5th gear. So my real question is will it work?.. That is, swapping the si 5th into the ZC tranny.
Mista Bone, I remember you from the CRX Perf forum... you would know. How big of a project will it be?
EDIT: --
I found this quote:
The nice thing about the ZC is the transmission. It is geared much lower then the transmission used for the D16 in the US. However, many people in the US do not like this transmission because they are turning so many RPM's on the highway at speed. However, it is a simple procedure to swap the 5th gear from the ZC transmission with 5th gear from the transmission that came with the D16 in the CRX. That will get you the low gearing and performance off the line and out of the corners that you gain with the ZC transmission but allow you to turn lower RPMs at highway speed.
