Mgb 5-speed Kit

MGB 5-Speed Kit

Drive shaft not shown in picture but will be included with kit.
Kit converts the 1968-1980 MGB to a quiet, durable, all synchronized, overdrive 5 speed transmission. The transmission used in this conversion is from a Datsun 280Z. This gearbox was used behind a powerful, fuel injected 2.8 litre engine in the Datsun, and was durable in that service. Yet, it is 23 pounds lighter than the standard MGB 4 speed. It is 0.864 ratio in fifth for quiet, reasonable RPM cruising. The conversion requires no modification to the MGB chassis, except to the bolt-in rear crossmember. No modifications are required to the engine.

MGB Kit Includes

  • A billet aluminum rear engine plate with a new crankshaft seal, to replace the original steel plate.
  • A new clutch disc that matches the standard MGB pressure plate.
  • A rear transmission mount bracket.
  • A complete new driveshaft with u-joint.
  • A speedometer angle ratio adapter and new speedometer cable to correct speedometer reading.
  • A clutch alignment tool.
  • A pilot bushing.
  • A billet aluminum slave cylinder, braided steel, Teflon lined hose, fitting, attaching bolts and push rod.
  • A modified flywheel, which has been modestly lightened, faced and balanced, with a new flywheel ring gear installed. (Exchange for your MGB flywheel.)
  • All fittings and fasteners required for installation.
  • Installation instructions, with color photos for clarity. Instructions include phone number to call if you need technical assistance. Included is a parts list of standard replacement parts that can be purchased locally, should you ever need them (clutch disc, throwout bearing, etc.).

Deluxe ez kit installation

Installation of the Deluxe EZ Kit is especially easy. It requires no welding or machine work other than drilling two 3/8" holes in the crossmember. Instructions are detailed with color photos for clarity. Anyone with the ability to install a stock MGB clutch will be able to install this kit. It should take only about two hours more time than the stock clutch replacement. Installation of the Deluxe EZ Kit requires use of a starter from a 1968 or newer MGB or an aftermarket starter for these newer MGB's.
