Duratech trans mission choices

[berg]

I have a project we are working on and need to know what my transmission options are for a Duratech 2.0-2.5 motor. I have a Mazda MX5 5 speed and access to a 6 speed also. This will be a track day fun car and maybe some endurance races also so durability is a must. Willing to spend if need be but don't want to break the bank.

The only other factory option is the M5OD-R1 from the Duratec 2.3L powered 2001.5+ Ford Ranger/Mazda B2300, but as far as I know nobody has a basis for comparison regarding durability in sporting/race use against the NC Miata transmissions. If you come up short on any of these, there is also an aftermarket bellhousing available that will allow the use of the venerable T5.

T5 was sort of the way I was leaning. do you know who make it?

It does use the Ranger flywheel, for which there is currently no off the shelf steel or aluminum replacement available yet...I'm currently working on that though.

There is also a guy on the Turbo Ranger forum who has put together a kit that will adapt a Duratec to SBF bellhousing.

Are they from a 2006+ Miata?

Yes the 5 and 6 speeds that I have already are 06+ But from my exp racing them in the MX5 Playboy series I question the ability to go 6+ hrs in a enduro.

Out of the UK, but you might give these guys a try:

If I were in your shoes I know what I'd be putting behind the Duratec - no reason to deal with "custom" anything and everything (literally) will bolt together.

A stock NC flywheel is the same diameter and tooth count as the Focus flywheel so the Focus starter will also work.
