/6 Conversion Clutch Question Options

[patssle]

For my 3.0L SC motor with Weber carbs to a 901 transmission - I'm planning on a new Kennedy 228mm flywheel and 228mm Stage II pressure plate.

My existing 215mm 914 4 spring clutch disc still has life left on it - can this be used at all? I've seen some notes that 215mm can be used on 228mm flywheels...is this true or do I need the 228 with 6 springs for a /6 engine?

Thanks.

A 3.0 to 901 conversion uses a stock 911 flywheel, a conversion ring (that also has the starter gear) and a heavy duty late bus 228mm pressure plate. The disc is also bus, but it's not much different from a 911/914 215mm disc.

The 4 spring on a stock /4 has clearance issues with the crank bolts when you resurface the flywheel, it may have clearance issue with the 3.0 crank bolts as well.
A 6 spring 215mm disc might work, but compared to the price of the conversion kit its cost is trivial, so I personally wouldn't bother reusing the old disc.

I'd use a stock 228mm bus disc...in fact that is what I'm using. BTW I also made my own conversion ring.
