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"

Can anyone answer my above question? or any other light flywheel you would recommend?

What are you going to use your car for predominantly?

A lightened flywheel will improve throttle response/willingness of the engine to rev and engine braking- good for performance driving.

But on the flip-side, it will make it less pleasant in traffic- you'll need to change gear quicker as mentioned, plus the car will be jerkier when you get on and off the throttle at low revs as well as accentuating driveline snatch...exactly what you don't want in a traffic jam.

Just like most things in life, you need to choose the amount of compromise ur willing to accept.

yeah im willing to accept that compromise. its all part of the skyline experience isnt it? if im afraid of the unpleasantness in a traffic jam i would be driving an automatic wouldnt I?

now just need someone to advice me on which lightflywheel to get :O

Just clarifying something, lightweight flywheels actually improve deceleration contrary to what someone mentioned earlier. Because of its weight, it has less inertia compared to a heavier one which will continue spinning for longer.

to summarise the thread.

An aftermarket flywheel is;

* Better for accelleration -------- in every gear.

* Better for the drags ------- If you can't change gears properly a heavy stock flywheel is more forgiving but, don't worry you will run slower times thanks to your heavy flywheel and the fact you can't change gears properly.

* Better for decelleration

* Better for the circuit/track use

* Puts less stress on the gearbox and makes matching rpm for shifts easier than factory.

A well designed aftermarket flywheel and clutch setup (they go together) for the road will not;

* Effect your fuel ecconomy

* Cause drivetrain vibrations or noise

* Change hill starting difficulty

Some more of my 2c;

Select a pressure plate with sufficient clamping force not one that is stupidly sprung.For example a 230rwkw gtst will get away with a factory level of pressure/clamping when matched to a good friction plate with metal/ceramic composition. The heat capabillity of the material is just like brake pads and plays out in use pretty much the same way.

Chrome molly flywheels have advantages in strength, wear and heat loads over factory units when using more aggessive friction plate materials, weight aside that is a good enough reason to look at them.

like i said, ive got the exedy flywheel with exedy cushion button and am very happy with it. i looked at other flywheels like you are now and chose the exedy one cause it was around the 6kg mark as i didnt want to go too light for daily driving and because i could get it localy and not have to wait for it from japan like the cusco one i was looking at. UAS offers chromoly flywheels at the light (6kg?) and super light (4.5kg?). thats another option for ya.

I found an exedy flywheel on Nengun http://www.nengun.com/exedy/single-sports-light-flywheel. Is this the one you are talking about?

It doesnt state the exact weight. Not sure if its chromoly either only says "lightweight aluminium" or "proprietary metal alloy" what does that mean?

yeah...info differs from nengun site and the exedy aus site and i was confused too about wether it was alu or chromoly and weight but from the research and info that i recieved theres only the one model and its forged chromoly and weighs just over 6kg. sulivan_a had a group buy on these and says the same i think. i got the flywheel for about $500 trade here through the mech, should probs ask your mech how much he can get it for.

yeah thats about right, a little under $500 delivered is Nengun's price.

I guess the "proprietary metal alloy" is refering to forged chromoly then. in that case it should be heaps stronger than the factory one.

    • So stock ECU does not like anything above 10 psi?  That Nistune one is just for "try" if it will be any different, I know it need to be tune for that. I know but YOU may know about these problem but i/we dont. They few little Skylines here let alone people who know anything about tham so that is why iam asking here  
    • So now we have a radiator with no attachments whatsoever. It lifts up with a particularly tight spot between the drivers side air box mount and the lower radiator outlet, but if you've got this far you will sort that too. This is the lower mounts with the rad out so you can see where the rubber bushes go, it is a straight shot upwards Done! Assembly is the reverse of disassembly, with blood less likely to be shed.
    • Right, onto the second last trick. The Air Con condenser is mounted to the front of the radiator and stays in the car when the radiator is removed. There are 2x 10mm headed self tappers holding the top of the condenser to the radiator, remove those The bottom of the condenser is attached to the radiator with clips. You need to lift the condenser out of those clips and clear (up, then forward). f**ked if  could work out how to do that last bit with the front bumper on. I hope you can, and you share the trick.  Bumper removal probably deserves its own thread one day once I've recovered the will to live, but basically you need to remove the wheels, front inner guard liners (clips and 10mm headed bolts), the self tapper between the guard and the bumper at the rearmost point of the bumper (same as an R32 that bit), any remaining clips at the top/front of the grill, an absolute bastard design with a plate that holds the top of the bumper above the headlight each side (only 1 bolt which is tricky to get to, but the plate catches 2 places on the bumper and must be removed....carefully!) and push clips between the bumper and guard under the headlight. If you've done all that you will be faced with wiring for the fog lights on both sides and in ADM Q50 RS at least, 4 nasty tight plugs on the driver's side for the ADAS stuff. So, the clips at the bottom look like this on drivers side (looking from the front) And on the passenger side (also from the front), you can see this one is already out Clearance on both of these are super tight; the condenser needs to move up but the upper rad support mount prevents that, and the radiator can't move down far because it is (rubber) mounted. Once you achieve the impossible and drop the condenser off those mounts so it does not stop the rad moving, you are good to go
    • OK, next the shroud needs to come off and there are a couple of tricks. Firstly, there is a loom from near the passenger side headlight to the fans, coolant temp sensor etc and there is no plug to undo.  In my case I was OK to leave the shroud on top of the engine so I just undid the passenger side fan plug and about 10 of the clips which gave enough free wire to put it aside. The fan plugs were super tight, the trick I used was a small falt screwdriver to push down on the release tab, then a larger flat screwdriver to lever the plug out of the fan unit....be careful with how much force you apply! If you need to remove the shroud altogether for some reason you will have to deal with all the plugs (tight) and clips (brittle)....good luck. I removed all of the clips and replaced them with cable ties that I will just cut next time. Also, in the Red Sport / 400R at least, the intake heat exchanger reservoir hose is bolted to the shroud in 2 places with 10mm headed bolts; so remove them (the hose stays in the car; no need to undo it at the t fittings down at the radiator lower mount. Once you've dealt with the HX hose and the wiring loom, there are 3x 10mm headed self tappers holding the top of the shroud to the radiator; remove those.   The shroud then lifts out of the bottom mounts where it sits on the radiator, up and onto the engine out of the way. Simples
    • Ok, disregard my “rate them” comment, sorry for my unrealistic input
