Dual Mass Flywheel Do Rs4S's Have Them?

[OMY31T]

hey guys i have a s2 rs4s and its knocking/rattling. ive checked it with a stethascope, and the noise is coming from the rear of the engine or bellhousing. i believe these have a dual mass flywheel and this is where the noise is coming from but looking for some clarification from anyone whos pulled a fly wheel out of one.

cheers.

Never seen a dual mass flywheel on an RB but then I haven't seen that many RB flywheels. I would think it very unlikely. On the other hand it is quite possible that someone has fitted a twin plate clutch if your engine has been heavily modified (they are not standard).

Or else you have a screw loose somewhere?!!

Sometimes I think you have to have a screw loose to buy a Stag.

NOT

umm..... by looking at excedy clutches and flywheels, and talking to my dad(owns a head and clutch shop in nsw) some GTR's have dual mass flywheels...

this is an oem replacement for a dual mass flywheel on an R34 GT-R

OEM equivalent clutch kit including DMF NSK-7725DMF

this is also for sale on SAU

from an R34 GT-R VSpec

Stock used

Used dual-mass flywheel now for sale - Will inspect condition and update. For now price = $250, may go up or down $50 depending on confirmed condition (will post pics)

so skylines definalty have them and i thought, being a NEO engine, with gtr gearbox(if that waht the awd box is), it may have the GTR dual mass flywheel. im not sure if the GTT had them, but its possible aswell.

i think i answered my own question after further googling it seems the Rs4s from 97 onwards has a dual mass flywheel

Well I remain unconvinced. From my "research" the only Skyline to have a dual mass flywheel as OEM is the R34GTR with the 6 speed Getrag although aftermarket dmfs are around.

I have an R33GTR box and clutch in my Stagea and the clutch and flywheel came out of a low mileage R33GTR and its a solid flywheel. I'll bet quids that the RS4s came out with a solid flywheel.

mmmm i guess ill just have to pull it out, because its really the only explaination for the noise that i can come up with.... it doesnt sound like piston slap, and all of the cylinder compression are good, i thought it may have been the idler or tensioner pulley for the timing belt, but they have been checked and are fine. the car drives beautifully so its unlikely to be an internal bearing.....

this has really got me by the short and curlys, its all thats stopping me from sending the turbo off to hypergear, got the FMIC, fuel pump, z32afm, hard pipe intake, all i need is the turbo and ecu + tune, but im not going to send it off and power it up if its going to cause more problems...

does the sound change when you push the clutch in?

As stated before, 6 speeds get dual mass flywheels a la 34gtr and s15

Quite likely to have copped a twin plate clutch in japland, extra likely if your clutch is quite firm

[pv35gt8]

Disconnect either injectors or spark down the back end of the motor (one at a time) and check if the noise goes.

If it does it will more than likely be big end bearings, Happened to me on my R33 a few years back.

My RS4S is a 98 and as i have the flywheel out sitting next to the gearbox on the floor, i can tell u its definately NOT a dual mass flywheel. The noise is prob the throw out bearing. Mine was noisy.
