Here’s a way to extract some extra performance from the five-bearing ‘B’ Series 1800cc engine as used in the 1968-1980 MGB, without making any modifications to the engine’s internals.

A Fidanza lightweight flywheel can easily be installed when you replace the clutch and will bring the following benefits:

  • Faster throttle response and quicker acceleration
    • Additional horsepower to the wheels (reduced parasitic losses)
    • Smoother, faster shifting
    • Easier braking, better slowing (due to reduced rotational mass)
    • Reduced clutch wear and improved efficiency (from better heat dissipation)
    • Cost savings and longevity (Fidanza’s replaceable green friction plate means there’s no need to replace entire flywheel when worn)
    • Potential for increased fuel economy (if you can keep your foot off the throttle!)
    • Quality and reliability (made in the USA from top grade materials)

The Fidanza flywheel incorporates a 127-tooth ring-gear and is suitable for the four-synchro gearbox.

The flywheel wears part number 126801 and retails at USD $500.49 plus shipping and tax.
