This package adapts a BMW ZF 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.

If you are interested in some additional KPower options, we offer a longer 5-speed transmission with our E30 Getrag 260 transmission package. We also offer our K or BP to BMW ZF 6 transmission option.

All parts included are proudly made in the USA.

While these components are often in stock, please allow 30-60 days for delivery. If you'd like to check lead time before ordering, email us at info@kpower.industries.

This package includes:

-Engine/transmission adapter plate, CNC machined steel, zinc plated, with all hardware (specific to the E36/E46 bellhousing bolt pattern, not compatible with the Getrag 260 transmission).

-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. Designed to bolt to an upgraded GM Getrag 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

-3/4” Wilwood clutch master cylinder kit with braided stainless clutch line

-E36 clutch slave cylinder, Sachs brand or equivalent

-BMW reverse light connector with pigtails

Notes:

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.
