FORGED PISTONS

These pistons are manufactured exclusively for us by both Cosworth and Omega. They are designed for competition and therefore are much stronger but are equally good for road use. They are a direct replacement for the originals and require no special liners, head gaskets, etc. To keep the compression ratio as high as possible they are machined in height to the upper-most limit and this means, if the engine block has been skimmed at any time, the piston top may have to be machined to suit. This is standard practice with all good engine builders and therefore should not pose any problem. These pistons come in sets of six, including gudgeon pins, circlips and rings. Please note: The sizes quoted are finished bore sizes and all tolerances have been allowed for on the piston. We have used metric sizes in order to take advantage of the latest piston ring technology.

Replacement rings available, please state diameter and width when ordering.

STEEL CRANKSHAFT

Made from EN40B and Nitride hardened, these are for the serious competitor who is looking for the ultimate performance and reliability from their engine. Having the original stroke and using std. main & big-end bearings. It can be used with standard or our Steel Con Rod Set MCENG632R, the flywheel fixing is 12 bolt which will line up to the standard flywheel and rear seal.

STEEL CON ROD SET

These Carrillo style English made con rods are considerably lighter and stronger than standard ones, using far better and stronger rod bolts. A direct replacement for standard or fits with our steel crank.

COMPETITION CRANK SUPER DAMPER

We import these special crankshaft dampers from the USA and then make our own pulley/boss to fit the MG engine. They will stand much higher revs and absorb the harmonics from the engine. Ideal to make a fast road car smoother and a MUST for race and rally cars.

ALUMINIUM FLYWHEELS

These are CNC machined from a solid aluminium billet with a ground steel friction ring attached to provide the clutch face.

The thin ring gear is fitted and grub screwed.

Made in England to our design.

These weigh only 4.6 Kg (10.1lb) complete.

So are very suitable for serious fast road and rally cars which wish to use the 9 1/2" clutch.
