what options do i have fot a tranny on a fox

[Moose Jr.]

Needs to handle 600 plus rw
What is my most cost effective approach?

Liberty Gear TKO 600, Spec stage 3+ clutch, quicktime bellhousing, never look back. If it's a track car, get the faceplated version. Be ready to spend some $$$ though.

My opinion, do it right the 1st time. Even if you have to wait.

Built C4. You will be happy.

The M5R2 RKE has fiber lined snycros. You're the expert on transmissions, but I know my Super Coupes. I haven't seen a single case of broken gears or input shafts on one of these transmissions.

I've never seen a carbon fiber lined M5R2 ring until 99-00ish and up F150 and Ranger. You might be right though, the M5R2 RKE is a very limited use unit and might have come with lined rings. As for strength, it's still a 10 spline shaft and that will twist over time in a heavy car, ask the Terminator boys about it.
