L28 flywheel to take the 240mm clutch

[rob240z]

As title says i'm after an L28 flywheel that takes the bigger 240mm clutch, currently have the 225mm and have gone through two clutchs in 800k's hoping the bigger diameter will solve my problem. be good to get one asap so i can use the car for labour weekend

RB ones fit and will be a lot easier to find.

Well that's handy to know so would an RB flywheel fit an L28? I will check that out tomorrow

[rob240z]

Do they bolt straight on? no mods at all? will the stock starter work? and are they all the same RB20,25,30 etc or is there a certain one to use?

[DJZ]

Bolt straight on, you may or may not have to shim the ID where it locates on the crank, I never did though, I used a 240mm RB30 one on my old 3.1.

RB's have the same clutch sizes, 225mm & 240mm, most people refer to them as 6 bolt and 9 bolt flywheels, that's the number of pressure plate bolts. Most 2 litre non turbos will have a 225mm clutch, almost everything else should have a 240mm but best to double check before buying one.

[DJZ]

Almost forgot, there's a very good chance you'll need a shorter release bearing carrier as the 240mm clutches are usually taller.

[rob240z]

Cool thanks for that i'll have a look into it. what did you get a shorter carrier from?

[DJZ]

It came off the RB30 gearbox, if you can get the one that matches the flywheel you should be sweet.

Also check the ring gear diameter my Stagea RB25det has a starter motor with a reduction drive. It is not compatible with non turbo starters

Oh and stay away from anything with a pull clutch.
