T50 to AZ6... a "new" option for gearbox issues

[oldeskewltoy]

The rear diff(6.7") is more stout then the T50... not by a lot... but enough. And in my case, I'm running a Richmond Racing 4.10 rear diff... quite a bit stouter then OEM. The MAIN reason I began this project was 2nd gear issues I've now had in two T50s. It is SOOOO easy to crunch 2nd.... and that is just operational problems.... the Road and Track quote STILL holds VERY true as well. The T50 is just not a performance based gearbox. It causes our cars to be slower.

Also, I don't actually have the specifics(they were on C4AG before it crashed) but each shift on an AZ6 from 7200 on the previous gear raises the next gears rpm engagement point.
1st at 7200, shift, rpm is at 4800 in 2nd(approx). 2nd at 7200, shift, rpm is at 5100 in 3rd.... and so on. Each shift moves the rpm band slightly higher, allowing for better acceleration in each successive gear.

This is being made to fit into our cars WITHOUT any cutting, or changinging of our cars what so ever!
The parts being developed are:
1) the adapter to close the AZ6 and accomodate a 4AG bell (see photo below... arrows indicate apprximate position of adapter)
2) the shifter section shortened by 8" so the shifter will fit through the stock shifter hole
3) a mechanical speedo drive to take the stock speedo cable
4) a trans mount that will fit the AZ6 and fit the STOCK cross member in the AE86
5) A shortened driveshaft with the AZ6 output yoke attached to the shortened driveshaft

banpei - as of this point it is a project... nothing is actually finished, other than the pattern to cast the adapter. BUT.... this project WAS designed for sale eventually..... that is why all the engineering is being done and not a quick slap/weld job like the photo below. I'm spending my money at this point to develop another option for our beloved cars. if you still would like me to PM you, I will...
