I am getting a new clutch put in and a lot of people have said.. Why you are at it you may aswell machine the flywheel, get a lightend flywheel...

What does a lightened flywheel do... Im told increases acceleration....

My dad wants to know.. and I need a reason that will make him think it is a good idea to get... He thinks its fast enough as it is...

Also if i were to get it done, what would i tell the mechanic to do... do they just drill holes in the current one to make it lighter?

It would be good to have an answer by 10:00 tomorrow.. thats when im taking it in...

Thanks,

It's best to get an aftermarket one rather than go down the route of lightening the standard one. I guess theres an inherent risk when lightening and machining that some structural integrity may be lost and possible inconsistencies could lead to failure.

And flywheel failure is not a pretty sight or so im told.

Ok the idear of having a lightend flywheel is that it will have a considerable loss of rotating mass which in turn makes the car rev’ easier and decelerate quicker into corners.

Its best to get a Billet Steel Lightened Flywheel, that has the strength as well as being lighter. Because Flywheels do let go! so stay away from the Aluminium ones. Stick with steel youl be safer and still have the performance advantage.

An aftermarket steel flywheel will be more like $600, but it is a worthwhile improvement.

Whatever you do do not try to lighten the stock flywheel, you cannot remove enough material to make any difference without seriously weakening the thing. Also you will need to balance it afterwards.

Either get a new steel one, or leave it stock.

ok then.. where could i get an aftermarket one from... I have $150 for it... That would be enough wouldnt it...  

Is there a particular size i should ask for??

What brand ect would be best??

So you say steel would be better/safer than alloy?

Thanks,

$150 will be lucky to get you a stock steel flywheel! :(

www.horsepowerinabox.com have one, its $395 bucks made for RB25DET, thats just the flywheel. its located here:

I get paid tomorrow and waiting for another cheque to clear for travel expenses.

Yes get discounted price plus shipping cost to mel, and check that it will bolt onto the new clutch u got

    • I'd just like to restate that I don't think anyone here is actually hating I recently sold a car part to a guy who was building a forged auto R34, with MV stall and aiming at ~450kw. I told him that I'm him, from the future and to stop after it explodes once. I told him I knew he won't listen the first time, and that's fine. But if my predictions do come true - Change direction faster than I did. I also said it's probably no coincidence that the dyno plot of a reliable turbo engine starts to look a lot like a N/A motor. :p
    • Got just the wing painted and fitted up to the existing boot. Big visual change and about time after having a GTR wing sitting in the shed since 2018 Headed up to Mallala with a quick obligatory stop in at Boliver OTR Oil control mods seems to have worked. I checked the catch can after session 1 and there was a dribble of water/e85 with barely any oil in it. After session 2 and 3 there was almost nothing and I stopped checking after that. so either great success or catastrophic failure/block of the external breather The GTR wing made a noticeable difference in the 160-185km/h sweepers. It was a very hot day for the cars at over 33C but the previously done cooling upgrade/ducting/water sprayers meant I never saw over 60C intake, 105C water and 100C oil and temps would drop back down very quickly once I shut it down. AD09's are a decent tyre but certainly and expectedly a step down when compared the the CR-S/AR-1 I have had on the car for years of track days. The handling characteristics of my car which I often describe using the Tony Hawks Pro Skater balance mechanic where either side of the center is understeer/oversteer was much more pronounced with no "green/safe" zone in the middle. However, imo it steers well/easily during oversteer largely thanks to the custom ACOSTAL front end. Enjoy a loose lap POV with my mate giggling away as a passenger.   Group photo for Peer Pressure Racing made it back home and gave it a wash Overall a great success compared to my previous two track days where i cooked the Starlets motor and blew up the new diff in the R32  
    • Nice. I'm looking forward to the updates!
    • Ayooo, been a while mates. I have a s2 r33 gtst and air stopped coming out of all the top vents.   My car has always made an actuator gear noise when turning the car on but that's a different issue I think? Did searches and am at process of thinking it's an actuator or some type of motor? I see a few different actuators and don't know which one. Would be nice to know if it was the one that's under the steering wheel so the dash doesn't need to come out.
    • Hi, just checking. Did you get this stuff made by Vspec Performance and at what price roughly? Looking into (sometime later) also getting such a intake kit, and Trust as well as HKS don't make a full set like this anymore.
