Hmm you sure it weights 2.5kg??? If so it must be made of carbon kevlar or some other exotic material?

I have 4.8kg chromemolly and the engine revs upto redline alot quicker and i dont see any negative effects with one

it was second hand sam from XTC picked it up for me out of a nismo clutch n poped it in... just waiting for my car!!!! he told me all about it i cant remember what it was but he researched it n new worth $900 n weighs 2.5kg unless my hears gone thats what he told me

Why do they make clutches pretty colours when they go INSIDE THE BOX!!!?!?!????!?!?!

So some crazy person will take the effort to make a see-thru housing with neon's that'll let you see the flywheel spin? LOL :)

sorry to bump this up. after reading through the whole thread Im still not very clear on one thing: does it really gives you faster acceleration say for 0-400m drag racing? or does it just "feel" faster because it revs faster?

Ive got a single plate Jim Berry clutch to be installed next week, if light flywheel is as beneficial as most you say maybe i should get one whilst the gearbox is out?

is this a good flywheel to get?

"Exedy - Single Sports - Light Flywheel

Low mass is a good thing when it comes to high-performance flywheels, which is why the lightweight aluminum Exedy flywheel can help your sporty street ride or weekend racer develop more drive-wheel power. A flywheel is basically an energy storage device. When the factory designs your flywheel, they take smoothness and other drivability factors into account and end up creating a heavier-than-necessary flywheel.

An Exedy flywheel still gives you great drivability, but the Exedy flywheel is made of lighter materials that take less engine power to accelerate. Your engine doesn't make more power and torque, but more power and torque gets to the wheels because your Exedy flywheel isn't soaking up as much of it as your stock flywheel did. Make sense?

Each Exedy flywheel is custom-machined from proprietary alloy metals and specially tuned to the vehicle upon which it is intended to be mounted. That way, your Exedy flywheel always gives you smooth shifting, scintillating acceleration, and steady idling characteristics that you'll love if you're a performance-minded driver. More importantly, you get back a handful of horsepower with an Exedy flywheel, which is what your goal should be with every modification you make"

So are you's saying, when you replace your clutch, you dont need to get a billet fly wheel machined?

also, can you get a lightened or billet fly wheel, lightened more? (if it can handle high power, and ur engine isnt taking a bit off could make it snappier and still safe?)

Just a quick question guys,

I'm getting a Daikin heavy duty clutch installed, and have the option to get a lightweight flywheel. I've heard that I will loose torque if I do. Is this true? Will I notice?

yes. and your gearbox will make awsome ratteling gear noises up to about 2k loaded up

Depends what you think loosing torque is.

I found the car felt as if it had more torque especially in first and second when accelerating. I.e it felt as if it accelerated faster.

Launching the car required more rev's as it would bog down easier.

I was able to feel road inclines much more.

Free reving the motor was felt more crisp

Rev/gear matching on corner entry was much easier

High rpm gearchanges seemed easier, appeared to reduce the occasional missed gears and crunches.

Overall.. I quite liked my lightened flywheel. I wouldn't be going too light though. 5-5.5kg's is what I would be happy with.

I can't say I noticed a rattle down low but I did notice an increase in a labouring type feel at real low rpm. With the stock flywheel on there was no labouring vibration type feel at all. Not that you should be selecting a high gear and going WOT at 1000rpm anyway. :P

for me (having driven a few cars with lightened flys) the biggest drawback is the greater rev drop between gearchanges. that is the main negative in my eyes. if you can live with that, go for it.

This is the only negative i noticed to when fitting and orc flyhweel, u just gotta change a little faster. takes u about 2 gear changes to get used to

:P

      RB26DETT Sketchy boost mod?

      By ARB26 · Posted

      I might be way off the mark here.. there must be a T junction under the manifold. That takes manifold pressure through a check valve prior to the T, one side splits out to this bleed off orifice, the other straight to the wastegate actuators.

      RB26DETT Sketchy boost mod?

      By ARB26 · Posted

      Carrying out some engine due diligence before my first drive in a 260RS that has been in storage for 10+ years, and found two lines that are susposed to be plumbed into the boost control solenoid. One of the lines (the wastegate boost supply line) to actuate the gates, had a bolt in one end blocking it. The other line (main boost signal line) from the very rear of the intake manifold (RB26DETT) and runs up to the boost controller had this pill in the end of it as seen in photos. Other than the obvious (T28 Ceramic turbos might well be cooked)  Can anyone shed any light on if there is any validity at all with this mod, bleeding a constant fixed rate of manifold boost pressure off through this 3mm hole?  Is it deliberate?  Was this a 90s Jap mod done to RB26's? Or has someone just fitted this without any idea of what happens to ceramic T28s if they are not gate controlled?

      This looks great! Awesome to have the 5 speed with an LSD in this. The Recaro's look like SR2's or SR3's. It's a shame they've been retrimmed as they would have looked sweet in their original colours. I think I'd want my agent to be a little more up front and informative too. I've never imported but I reckon it would make me a little nervous, so the more info the better.

      Thanks for doing that Duncan! Makes you a good person in my books. We don't get kangaroos or wombats here. But we have bats and it's similar. AFAIK it's often the mums with a baby attached that get hit because they drop lower when starting from a tree. If you hit an animal, check on it. https://www.ifaw.org/au/resources/wildlife-rescue-app An app to get the closest wildlife rescue contact.
