    CLUTCH

    All m20 engines have the same clutch fitment... However it must be a version from SINGLE MASS Flywheel.

    There are different part numbers for different models but they will ALL fit this FW providing they are SMF version.

    Some OEM part numbers for Clutch kits

    21211223119 or 21211223102

    It is recommended to check the slave cylinder piston travel and make sure it sits at about 60-70% compressed when installed.

    Many heavy duty aftermarket clutches with improved clamping force are available if your application requires increased torque capacity such as racing or turbo engines etc.

     

    Myth Buster!!........

    It is a common perception that a large flywheel is used to increase the torque of and engine and with a light flywheel an engine will have less torque but this is NOT the case! Heavy flywheels are used only to ease the smooth engagement of the clutch so Grandma can take off without stalling the engine and that's it! maybe improve idle quality a little also. Once the car is rolling and the clutch is fully engaged the flywheel becomes completely unnecessary because the entire vehicle and its drive line becomes the flywheel storing huge amounts of momentum. Any additional weight particularly on the crank shaft only reduces the vehicles ability to accelerate briskly. So if Grandma isnt going to drive your car and you don't mind having to use a little more finesse with the clutch pedal then you will enjoy all the benefits of having a responsive engine with much improved acceleration. Even if its only a daily driven road car. We have many satisfied customers driving around on these flywheels every day just find and ask someone and they will be happy to report that drivability is not compromised at all, but the improved response and acceleration is very pronounced!
