Five Speed Mazda Gearbox Conversion

We are pleased to offer this new 5 speed gearbox conversion kit based on the Mazda MX-5 gearbox. The conversion uses a brand new MX-5 gearbox, giving the MGB GT V8 conversions the slick gear change that has become synonymous with the MX-5, and a relaxed cruising 5^th gear.
The kit fits MGB GT V8 conversions fitted with a V8 engine but using original MGB 1800 Salisbury Axle with 2.75” hole PCD in axle flange. The gearbox replaces the original 4 synchro non overdrive unit.

The kit is supplied with a fully assembled gearbox with a bespoke cast bell housing & casing designed to fit directly to the MGB GT V8 engine back plate. The bell housing flange has been designed to resemble the standard gearbox, preserving engine bay originality.

The conversion uses the standard MGB GT V8 flywheel & clutch cover and a new OE Mazda clutch plate is supplied with the kit. Installation is simplified with no cutting or permanent modifications required. Many of the components are preassembled to the gearbox and only require connections to the car.

The kit includes:

• Brand new Mazda 5 Speed gearbox assembled into custom casing & bell housing
  
• Concentric clutch slave cylinder assembled with pipework
  
• Mazda OE clutch plate
  
• Mazda OE gear knob
  
• Custom gearbox mountings
  
• Speedo drive & cable
  
• Bespoke propshaft
  
• All parts & hardware for installation
  
• Now includes new clutch cover
  

Please Note: The gearbox is prefilled with SAE 75W-90 oil.
