Adapter plate allowing the connection (swap / conversion) of the longitudinal Nissan KA24 (KA24E / KA24DE) engine (RWD – including Nissan 240SX S13 / S14) with the modern 8-speed automatic transmission ZF 8HP (ZF Friedrichshafen) from BMW – 8HP50 / 8HP51, 8HP70, 8HP75, and 8HP76, in both RWD and xDrive versions. The adapter plate is designed for ZF 8HP transmissions with a small bellhousing and a torque converter mounted with 6 bolts. The kit includes an aluminum gearbox adapter plate and a reinforced torque converter adapter with a starter ring gear.
Planning to pair a Nissan KA24 engine with a durable automatic transmission in your Nissan 240SX, BMW, or another rear-wheel-drive platform? The ZF 8HP offers 8 gears, lightning-fast shift times (approx. 0.2 s), and exceptional torque capacity – ideal for a daily driver as well as turbo drift and motorsport builds.
In our catalog, you will also find an 8HP shifter / gear selector and a standalone TCU controller with wiring harness for operating the ZF 8HP transmission.
The aluminum gearbox adapter plate has been engineered to make installing the ZF 8HP transmission as straightforward as possible. The reinforced torque converter adapter with starter ring gear (included in the kit) mates the KA24 crankshaft directly to the torque converter of your ZF 8HP transmission – an OEM automatic flexplate is not required. Gearbox adapter plate thickness: 25 mm (0.98").
