Mazda gearbox issues...

[lightyearman]

As some of you may know, I have a Mazda B2000 pickup with a late 80's (FC type) RX7 13B engine and gearbox fitted.
The gearbox is knackered, leaking, whining and popping out of first.

As not many RX7's where produced compared to other models, does anyone know if another Mazda gearbox is a straight bolt up replacement?

The rotary lumps don't make any sort of scary torque and the truck is quite light so I'm not fussed about how strong the 'box is.

Any help would be grand

FD (and Renesis?) has pull type clutch, unlike the FC.
You would need flywheel, clutch etc and needs some further mods.
There are a few breakers on the FD:UK forum, sometimes cheap. Avoid eBay sellers, they are ludicrously expensive., but that's generally the way with RX7 parts unfortunately.

I'd just get the box rebuilt or find another one.

BTW, Mazda MX5 gearbox bolts up to RX7 bell housing

Is this any of the early MX5 gearboxs!? If so that's cracking news, I can get an early 1.6 box for buttons. Will it work with the FC RX7 clutch and flywheel?

Thanks in advance

Do a google search, folk use the MX5 gearbox /13b bellhousing /13b on kit cars, MX5 boxes have close ratios.
