Hi all,

Firstly, I'm the first to admit I have almost zero knowledge in this area... so please keep that in mind. I had a jap twin in my GTR (ORC 709D), but after pulling it out, we found hairline cracks in the flywheel (not cool), I haven't owned the car that long so I can't tell you about the history of the clutch and it's usage.

Anyway, I'm going to go a Jim Berry "full monty"... basically, I'm trying to work out what flywheel to use. He recommended a stock one, but most people seem to highly recommend a lightened flywheel. He said he can source an aftermarket one for $600, but I don't think it was lightened. Can anyone set me straight on what I should be doing/buying? I will try to buy a 2nd hand stock item if they are good enough as I imagine it's cheaper, but I'm also happy to pay the money for a new one if it's recommended? Or can I buy a lightened one? Blah, i'm confused!

Thanks,

Tommo.

There are good points and bad points about lighter flywheels.

The lighter they are the quicker your car will seem to go through the rev range.But the revs drop quicker when you change gear.Some people even opt for heavier ones(drag and drift) as the momentum of a heavy flywheel means the revs wont drop as quick.

The main difference IMO is what the flywheel is made from.The stock one will be fine as long as it has not been machined too thin.

Im looking to get a 5.5kg chromolly flywheel in the next week or two.

On a side note the HKS Cyber Evo uses a stock flywheel.

Thanks for the comments so far :D

I found hairline cracks in my flywheel (it does get a lot of abuse). I went to billet steel instead of cast iron to make sure I never have a problem

Was your flywheel the stock one? Which one did you go for? Lightened or not?

Cheers!!

yeah mate it was the standard cast one. new one is lighter than stock but solid not cast. remembering it's not exactly for street use, but after seeing what happened to ben's one I didn't want to take a chance with my feet

    • Unsolicited advice? Keep the engine as close to stock as you can. Nothing wrong with adding some boost and making a little more power, but given where you are, you really don't want to try to make it into a monster. I can't imagine the roads are up to it, and the lack of locla support when it grenades will be a ball ache. FWIW, If there is a dyno around that you can access, then brand new injectors are a good idea, which will lead you to (at least) putting a Nistune in it, which will allow you to put an R35 AFM on it, all of which will make it possible to make it much much nicer to drive and live with.
    • List all of your mods. It sounds like an aftermarket ECU hitting rev limiter. Like a valet mode, or a cold rpm limiter? 
    • @Kapr Haha yeah thats the one. I missed that you had a built up engine, I wouldn't want to run it on there either then. It was good in my situation just to replace the original turbo on a stock engine. @MBS206Yep definitely not a replacement for anything name brand
