Well, I always learn the hard way... fortunately there wasn't much cost involved, less a couple hundred dollars and a few hours, before I found out the transmission I elected wasn't the best choice. With my M46 slowly starting to show it's age, I've been investing time and research into other options for a custom upgrade.
I know there's been success with the T5 and the Getrag 5-speed options, when mounted behind a turbo Redblock, but I'm interested in narrowing down the 6-speed options to a handful of candidates.
I chose the Aisin AZ6 from a Honda S2000 because the shifter location, output flange configuration, overall size and power handling to be ideal for a 240 with up to 350ish hp. I thought it had a simple removable bell housing, however, now that I've got the transmission in front of me, I see the bell housing is integral with the front cover, and removing it would leave 1.5-2" of transmission open, exposed and loose. It'd require, at least a custom front cover, that'd then accept a Redblock bell housing.
So, here's the riddle, is it economical to assume I can have a custom front cover made for cheap, and have it accept a stock or modified redblock bell housing? Or do I leave the S2000 transmission alone and consider other options?
Other options to consider...
Tremec T56, but I'm worried about gear ratios, cost and size
ZF-whatevs? from a BMW or Nissan 350Z, dunno why I wouldn't consider these.
Anything else to consider?
Anyone able to machine a way to use the Aisin AZ6 for under $1,000?
I know there are some smart people here, and plenty who are creative, so thought I'd ask.
I really like the idea of a close ratio 6 speed...fun for the twisties and auto-x and still one for the open road. My conclusion on the AZ6 might have been a little premature and undereducated, but I'm open to input. I know the Mazda, Toyota and Honda tuners really like the AZ6, as it's light, shifts beautifully and handles an impressive amount of power.
And to satisfy those just jonsing for pictures, here's my AZ6...
