Custom selector joint (no more worn plastic bushings) and stainless steel shifter pins, with retainer clips. Our design eliminates all components that often result in a sloppy BMW shifter. Custom length selector rod, stainless steel, dual sheer design. Ball bearings replace the OEM BMW plastic components for improved shifter action. The shifter has ZF 6-speed specific BMW geometry on the bottom. Short shifter, stainless steel, with Miata geometry on top (Miata 10x1.25 thread pitch, height, shape, and throw are identical). This flywheel (12 lb.) bolts directly to the BP or K crank and accepts a 240mm E46 clutch kit, 22 spline.
A specific BP or K (+$100) to E46 6-speed flywheel (different geometry than the 5-speed).
#E36 SHORT SHIFTER REPLACE SERIES#
Engine/transmission adapter plate, for either Mazda BP or K series engine CNC machined steel, zinc plated, with all hardware and dowel pins. This package includes the following parts: Unlike our ZF 5-speed kit that includes a transmission mount that bolts inside the tunnel, the ZF 6-speed kit includes a set of V8R frame rails, a rear crossmember, and a rear transmission bracket that accepts a poly GM style rear transmission mount (very similar to the T56 style mounts on the market).īP or K to ZF 6-Speed Transmission Package: $2995.00 The upgraded components will be welcome for our high horsepower customers. There is a minor increase in NVH when installing this kit thanks to the firm transmission mount, but nothing overwhelming. The shifter action is quite good: crisp and precise, and mimics the Miata shifter geometry perfectly. Our transmission kit provides everything needed for a bolt-in transmission upgrade. So a clutch disc specific to this transmission is a requirement. Note that the ZF 6-speed uses a 22 spline clutch disc, unlike the ZF 5-speed that uses a 10 spine disc.
The pressure plate on this clutch is also found on the E46 M3 and E39 M5, so it’s up to the task to handle turbo 4 cylinder torque in many applications. This transmission also allows us to use the inexpensive OEM replacement E46 6-speed clutch kit that pairs with our custom flywheel. The rear of this transmission is not able to be easily mounted in the Miata tunnel and so our mounts and flywheel are design specifically for the ZF 6-speed. Please note: The Getrag 420G transmission found in the E46 M3 is not compatible with this kit. Check out our gear ratio calculator to configure the best transmission and differential combo for your setup. They fit inside a Miata without any transmission tunnel modifications, and they are also readily available used for reasonable prices. These transmissions have been known to handle 800+whp in BMW applications. It's a compact 6-speed gearbox with comparable gearing to the Miata 6-speed, but MUCH stronger. Neither of those are compatible with this 6-speed kit) (Note the these cars were also available with the ZF 5-speed transmission, as well as an SMG 6-speed. The ZF 6-speed transmission used for the kit is the GS6-37BZ, found in the following vehicles: Once these are sold out, we will have more in stock in another 30 days.įinal product photos are in the works now and will be on the site soon. The initial production run is just 10 kits. These same adapters and flywheels will be available separately for those completing one-off projects. Adapter plates and flywheels are available to work with both the Mazda BP and Honda K series engines. We now have a parts package that bolts an E46 6-speed transmission into the NA and NB Miata chassis.
Anticipated lead time to ship orders is less than 30 days. Our transmission kits are 100% proudly made in the USA. We’ve completed our BMW E46 6-speed transmission testing and are now ready to take orders of these long-awaited kits.
