OS Giken clutch/flywheel

[Alphabettispaghetti]

I’m getting all the bits together the the engine machine work that’s needed.

I’ve realised clutch flywheel should really be taken along for dynamic balancing on the crank.

Out of the OS stuff, what have people gone for? Was it worth it? Which type of clutch did you get?

I’m only aiming for a puny 150bhp at the wheels but I’d like a ‘light’ feeling engine.

Or what others should I look at?

Lots of choice out there and everyone will have an opinion I’m sure. For my ZX, after trying several combinations, I finally settled for a Fidanza lightened flywheel

Mainly due to the replaceable friction surface.

As for a clutch I (had several try’s with other makes to varying degrees of drivability) finally went for an XTD stage 2 clutch

I haven't used OSG stuff - I've used:
a) lightened OEM 240mm flywheel plus ACT clutch (heavy pedal!)
b) XTD light(ish) RB26 flywheel and clutch (normal pedal I think, lot of work to make it fit).

If it helps used I’ve had installed a light weight billet competition flywheel from Conceptua tuning (c£340) and Exedy OEM replacement clutch (c£70).

Are you staying with 225mm.

 

[Kieronpollock]

Yep as advised by my restorer. short shifter added to the stock 5 speed too

I've zero practical need for a 240mm one.

 

[Rob Gaskin]

Ok you save about 4lbs then.

I think rotating mass is worth about 4 times the given weight.

as I'm in idiot. I found I've got a new Fidanza and clutch hidden away. Need to dig it out to check which actual one it is. however, it looks like I can spend the money 'saved' on Bluemoon.
