The standard MGA axle ratio of 4.3/1 gives 17 mph per 1000 rpm in 4th gear. This means that at 70 mph the engine rpm is 4118 rpm, which is high compared to modern vehicles with five gears.
The conversion adapts a Ford Sierra Type 9 gearbox to the MGA 1500, 1600 MkI, 1622 MkII and Twin Cam MGs, ZA-ZB. MGB 1800 engines can be installed with additional parts, which we can supply.
A modified Sierra gear change mechanism is supplied with replica MGA Chrome gear lever which is situated in exactly the right place in the car so the conversion is undetectable. The Quickshift mechanism, which incorporates a special PTFE bearing that produces a slick, short gear change is now standard equipment. This standard feature is a $95 option on other kits. With this option you do not have to modify the tunnel cover.
We offer expert advice and are available to help during the installation process. Call us at 904-282-1658 or 904-613-9591 (cell).
