This adaptor plate will allow you to fit a Mazda MX5 NC N7 5 speed gearbox behind your Crossflow or BDA Engine and put the starter motor on the drivers side in the standard 105e Anglia position.
The plate is laser cut to ensure accuracy and repeatability so all adaptor plates are manufactured and fit the same.
The top two countersunk holes are used to align the centre line of the adaptor plate to the centre line of the crankshaft. The plate is supplied with the two countersunk 3/8 screws for this. There are 2 dowels welded into the adaptor plate that then line the gearbox to the crank centreline.
Your gearbox will need notching slightly to clear the nose of the starter you are using.
The starter motor is mounted on the drivers side the same as a standard 105e Anglia and clears the 105e crossmember.
Crossflow engines use a standard crossflow flywheel and 3 bolt starter motor and one of our Heavy duty crossflow Mazda NC sprung centre clutches. These are found by clicking here. You can use any steel aftermarket flywheel and its matching starter whether it is 110 or 135 tooth.
The adaptor plate is supplied with all fastenings to bolt the engine to the adaptor plate, the gearbox to the adaptor and the starter to the adaptor plate. See attached drawing for fastener sizes and positions.
THE INPUT SHAFT COVER MUST BE CUT DOWN BY 10mm WITH THIS CONVERSION AND THE RX8 BEARING BE USED.
