teveo,

The difficulty is that your 901 transmission is configured for the 215 mm push-type clutch.
The important feature is the location of the pivot for the clutch arm.
This location will not work with the arm for the 225 mm pull-type clutch.
Several have welded a new boss in the transmission case with varying degrees of success.

The ‘as original’ solution is the 906 flywheel and suitable light-weight disc and pressure plate.
There are excellent reproduction 906 flywheels available.
Be sure to use a street-type spring-center disc.
These are 215 mm push-type and work very well with a 2.0 (I race with this clutch using a 2.6R engine).

If you feel you must use the 225 mm push-type clutch, changing the transmission to a type 911/01 5-speed is a good solution.
The same ‘airport gears’ fit.
This has the added advantage of using the larger (911/914/915/930) differential and readily available LSD.

Be careful to not mix-‘n-match clutch parts here.
The 2.2 and later flywheel uses a thinner 6-hole ‘flywheel washer’.
The 2.2 and later uses six shorter XZN flywheel bolts.


Use the standard SWB Lobro axle assemblies.
They are the correct part and are long lived.

Best,
Grady
