My turbo MX-5

Now that I once again have to change the gearbox I might as well get a better clutch
quick summary of my previous clutches
FM level 1 Slipped Only good for a GT2560
FM level 2 Slipped uses the same disc as FM lvl1 and slips almost as much
949racing/Competition Clutch Twin disc Destroys gearboxes enough said
I guess that left me ACT xtreme clutches that Soviet and others here use
This maybe? ZM4-XTG6 - XT/Race Sprung 6 Pad
or this: ZM5-XTG6 - XT/Race Sprung 6 Pad
I have no idea what’s the difference between those two

Bundy seems to have even bigger problems with sprung clutches breaking his 6 speeds than unsprung though.
You could always just turn the boost down, like me. And my ***** 5 speed saver tune.

Time to cast your own T5 adapter bellhousing....

Isn’t T5 only rated for 300 lb ft?
I've been thinking something like Getrag 420G (368 lb ft) from M3 bmw but its little bit costly 2000-4000$.
Then there’s a fairly common R154 "truck gearbox" from Toyota Supra/ Soarer/Cresta that lot of my friends use on their 700whp drift cars. That gearbox take 500 lb ft all day long and those boxes goes around 1000-1500$ in here. Even the gear rations are kind of ok compared to my current 6speed: http://www.miata.fi/kuvat/lootatv.gif

I haven't ruled T5 out just yet. Their derivatives have been used in Cosworth Sierras, including 500 hp A-group ones in road racing, the configuration is close and there are quite a few companies modifying them with wider straight cut gears and dog rings.
Companies like G-force claim 500 ftlb torque and the stock transmission is said to weigh only 75 lbs.

Yeah, G-Force claims their upgraded T5 will hold 500ft/lbs in a 3000lb car launching on slicks.
G-Force Transmissions and Long Shifters
The Getrag 420G has very nice ratios and I would love to run it. But the weird 3-bolt output flange confuses me.
G-Force Transmissions and Long Shifters
Generally, it can be assumed that with the available upgraded mainshaft, the G-Force Street 5-Speed kit will handle roughly 600 hp or 500 ft-lb. of torque in a 3300 lb. vehicle running drag radials at the track with a moderate clutch upgrade.

Can RX7 turbo2 gearbox take 450ft/lbs?
- it's cheap (400-500$ on ebay)
- there's adaptor for it Miata BP/RX7 TII Transmission Adapter Plate - Maverick Motorsports
- gear rations are "kind of ok" www.miata.fi/kuvat/t2ratiomph.gif

Muoto! Just reviewed your build. I realized that you're running Federal's RSR and I'm thinking about getting some. How do you like the tire? Are you running a 205 on a 9" 6UL?
Still love the build.
