904 Bracket Racing Transmission

That recipe is a mix of Tony and mine works well.

The WIT transmission site has been a disaster since the "improvements"...

Definitely go 5 clutches. Buy thin rear clutches and steels for the front drum to make a 4 clutch drum into a 5 clutch. Sometimes it may require a quick surface of the pressure plate to gain required air gap on the pack.

Most all of the "trans builder" kits are nothing more than a transtar or similar kit reboxed and marked up.

They are cake to build, nothing difficult and requires no special tools. Any tools that you may need can be made pretty easily.
