You use a Z clutch and flywheel with this swap. So look at the typical upgraded options like Centerforce, Spec, etc.

Thanks rich. Have you done the conversion ?

Not yet - but the parts are all sitting in my garage! I'm planning to refurb all the suspension and am aiming to do everything, including the swap, in one big hit. It's having the time though and it's all slipped to #3 on the priority list for the year (behind new head gasket and getting bonnet repainted due to micro-blistering).

...........What clutch and flywheel option is there ? I'm running 320bhp with 370ft Ibs......

Leo, if your current clutch and flywheel handle the power/torque ok stick to those (obviously check for wear).

Just in case you don't know:

If you start mixing and matching things then just be aware that you need to match the release collar to the pressure plate. Have a search on here - generally speaking the 225mm and 240mm clutches need different collars because the clutches are a different depth (distance of 'spring-fingers' from the flywheel). If you get it wrong you may not be able to get enough 'travel' to operate the clutch.

Ok great . Once I'll remove the box then I'll know what flywheel I'm using . At the moment I am using a 5 speed box so I take it there is 2 different sizes of flywheel ?

There's a 225mm flywheel and a 240mm one. I think 240 was used on later 260 coupes & 2+2s.

That's what my car is running now . I don't aim to go anymore than that . It's only used for the street and only used when it's drive . Lol

That's the thing though . There is plenty of skylines running around the 400ish mark with the standard flywheel.

I'm just happy to drive it really .
