Mazda BP to BMW Getrag 260 Transmission Adapter Package
This package adapts a BMW E30 Getrag 260 5-speed transmission to an NA or NB Miata with the original 1.6L or 1.8L engine. It's designed to provide customers with high horsepower turbocharged builds with a very stout transmission option. Interested in a 6-speed transmission? Subscribe to our newsletter for updates.
The Getrag 260 is an extremely stout gearbox found in the older BMW E30 325i cars. It features longer gearing than the ZF 5-speed (E36 and E46) and is especially suitable for customers that want longer gears for street use, or those who prefer to keep the Miata differential ratio.
All parts included are proudly made in the USA.

This package includes:
-Engine/transmission adapter plate, CNC machined steel, zinc plated, with all hardware (specific to E30 bellhousing bolt pattern and not compatible with E36/E46 transmissions)
-Flywheel that bolts to the BP engine and accepts an OEM style E46 clutch kit (13 lb, 6061 aluminum), with replaceable friction surface.
-Short shifter, stainless steel, with Miata geometry on top (Miata 10x1.25 thread pitch, height, shape, and throw are identical). The shifter has transmission-specific BMW geometry on the bottom. Ball bearings replace the OEM BMW plastic components for improved shifter action.
-Custom length selector rod, stainless steel, dual sheer design. Our design eliminates all components that often result in a sloppy BMW shifter.
-Custom selector joint (no more worn plastic bushings) and stainless steel shifter pins, with retainer clips.
-Shifter plate, billet aluminum, that bolts to the top of the Miata transmission tunnel and replaces the rubber Miata outer boot. It accepts the BMW shifter ball bushing and our custom short shifter in the center
-Steel 500+hp rated driveshaft. Can be configured to bolt to a GM Getrag diff (recommended) or a solid-mounted Miata Torsen diff.
-5 speed rear transmission mount, powdercoated steel, with all hardware (tunnel mounted)
-Upgraded rear transmission rubber or poly bushings, 3 hardness options available
-13/16” Wilwood clutch master cylinder kit with braided stainless clutch line
-E30 clutch slave cylinder, Sachs brand or equivalent
-BMW reverse light connector with pigtails
-Optional KMiata shift knob in black Delrin or stainless steel, with the proper BMW shift pattern (reverse is to the left and up, instead of right and down).
Note: An E46 clutch kit must be used with our flywheel, specifically a clutch kit for a 328i or 330i 5 speed car (10 spline, 240mm clutch disc). It must be a kit that includes a pressure plate designed to fit an OEM E46 flywheel. Additionally, an E30 pilot bearing must be used in place of the E46 bearing.
