MGB 5 Speed Transmission Conversion
MGB 5 speed transmission conversion with a modern smooth-shifting transmission lowers highway RPM to improve cruising noise and fuel economy.
Add a modern 5 speed transmission to your MGB This is a bolt in kit using a Nissan FSW71C transmission and requires no cutting, fabrication or welding. This conversion is 70lbs lighter than a stock configuration. A lighter flywheel allows quicker acceleration of the engine but still has enough mass for street use. A reduction gear starter adds power and reliability. A modern Nissan 9. clutch assembly combined with a long throw slave cylinder and short shifter offer precise quick shifts. An electronic programmable speedometer allows easy calibration and accurate speedometer readings regardless of gear ratios and tire sizes. Taller gear ratios allow relaxed around town driving with less frequent shifting and quieter highway cruising and lower engine R.P.M. The transmission has a lower parasitic loss than a MGB unit providing a noticeable power gain. With a torque limit of 435 FT/LBS this transmission is extremely reliable. Gear ratios: 1st: 3.321:1 2nd: 1.902:1 3rd: 1.308:1 4th: 1:1 5th: .759:1 Overall weight of the transmission is 90 lbs 35 lbs lighter than a MGB o/d transmission.
