K Series Miata to BMW ZF 5-Speed Transmission Adapter Package

This package adapts a BMW ZF 5 speed transmission to a K series powered Miata. It's designed to work with all existing KMiata swap kit components and gives K series users a very stout transmission option to handle huge power. Interested in a 6-speed transmission?

All parts included are proudly made in the USA.

This package includes:

-Engine/transmission adapter plate, CNC machined steel, zinc plated, with all hardware

-Flywheel that bolts to the K series engine and accepts an OEM style E46 clutch kit (13 lb, 6061 aluminum), with replaceable friction surface.

-Custom extended release bearing (required to keep the weight low on our flywheel)

-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.

-ZF 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

-E36 clutch slave cylinder, Sachs brand or equivalent

-BMW reverse light connector with pigtails

-Installation instructions (view and download here)

-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 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. Use Honda flywheel bolt 90011-RDB-000 only.
