TII Transmission Adapter plate for miata!!!
#67
would really like to get one of these in the up coming months just to let you know the market potential is still real don't get bummed miatas have very little in the option department for transmissions once real power is made and this is a great viable solution if you had a ppf adapter people would probably opt for this and quaiffe would prolly have to cease gearset production ha but people don't all need them at once and word has to get out I mean I've been researching trans options for weeks and just now found this through some guy mentioning it on another forum about a t5 swap but for what it's worth I think it's great

It's been talked about forever and ever and Here they are, adapter plates to put a TII transmission onto a miata motor. TII transmissions are significantly larger than stock miata boxes and are documented to hold well into the 400-500whp range. I broke 2 miata transmissions with 200whp.
CAD Designed, CNC machined, made in the U.S.A. Plates are laser scanned and converted into solid works and CNC machined for a quality, final product.
$450 SHIPPED in the CONUS with the plate and hardware you need (Plate to motor, trans to plate, and starter.)
Stock miata parts used:
miata slave cylinder, throw out bearing, pilot bearing, 5 speed starter
What you need to buy:
NC miata clutch disc. (1.8L clutch/flywheel only)
(replacement discs are CHEAP)
Turbo II transmission
Custom Driveshaft (I recommend Shaftmasters (aluminum) but local driveshaft shops are usually capable)
What you need to make/modify:
Space out stock FC clutch fork with 2 washers (make up for plate thickness)
PPF solution
(Differential mount/transmission mount, Adapting Trans to accept PPF)
(several roadster owners have documented solutions to this problem already)
Notch V shape in bellhousing to accept miata starter
Not for dog box transmissions, do not put plate on your dog
PM me with any questions, inquiries, or if you just want to buy this and stop worrying about transmissions.

I have three from the second batch left. I lose track of PM's and don't usually respond until I have an answer from the machine shop. Sorry for the delay for the most recent folks who were interested
