sr flywheel or RB ?

[preston240sx]

Ok so i just my flywheel bolted up and go to put the clutch on but the clutch wont line up so they either sent me the wrong clutch or i have the wrong flywheel .... will a sr flywheel bolt up? or did i get sent the wrong clutch?

lemme know thx guys

return the clutch, dont even try to make something that you have no idea what it is fit.

i bought the clutch on ebay said it was for a rb20det but it wont fit ... thats why i wondered if a sr will bolt up cuz the place i bought the motor from could of gave me the wrong one ?so now i'm stuckwondering which one is wrong .... im jut going to go to autozone get a oem 300zx na one tomarrow

so here's my flywheel does this look like a rb20 or a sr I'm hoping the shop i got the motor from did'nt mix things up ...

if it helps can some tell the difference if this is a rb or sr transmission

[race4fox]

Thats definatly a RB20 transmission, and the flywheel looks like an RB20 as well. I dont know what flywheel cross-reference number that RB's use, Ive heard a Z31, but I wouldnt believe that until I saw some proof.

Im in the progress of replacing the clutch in my RB right now, I just ordered a Clutch Masters clutch kit w/o the flywheel from a NA Z32. I suggest you do the same and send that kit back and just have your flywheel resurfaced...

i went to napa on saturday to get a 300zx NA clutch but it did'nt fit ... what year 300's is the clutch u ordered for i tried one for a 92 and was too big ?

[race4fox]

I ordered like a 95, it just arrived yesterday so I havent checked it out yet. Ill put it in probably tomorrow morning, so Ill let you know then how it fits.

could you measure the diameter of the clutch? if the clutches to big I wonder somebody stuck a flywheel from a L series on it some of them are 225 mm the RB 20 is supposed to be 240 mm

[preston240sx]

look at the 300zx thread it has pics

[race4fox]

My new clutch looks to be the exact same size as the OEM one, give or take 1mm possibly. Sounds like they sent you the wrong clutch, order a good clutch for a 95 300ZX NA from a reputable company like Clutch Masters or Exedy, youll end up spending more money, but youll like the pedal feel and grab a new clutch from one of those companies offers.

CM has like 7 different stages, I got a stage 3 (FX300) kevlar solid sprung disc thats rated to a ballpark of about 350-400hp with a wear life of about 70k miles. I paid 378 shipped for the clutch kit and 52 for resurfacing the flywheel. Best deal IMO.

Ill post some pics of my install if ya want as soon as I find my camera...

[preston240sx]

well im thinking its not the clutch but maybe the flywheel someone said that i might have gottena rb20de instead of rb20det flywheel sound like a poss answer?

[race4fox]

Yeah, I just read that thread. It definatly makes a difference. I didnt know you did a auto-manual swap...

Get ready for a kick in the nuts because flywheels arent cheap, and are pretty hard to find used.

[dnlx5]

ya sr flywheels are 8 bolt ka are 6 bolt dont know if it will fit but i have a ka fidanza one for sale good luck i also got a CM stage 2 clutch. Its possible that i had some oil leakage problems that got on the clutch but i have had poor reliability with this clutch i wish i had bought an exeedy

z32 90+ 300zx should bolt on to the rb flywheel. measure your flywheel diameter, make sure they are 225mm, if not then you may have a non-factory flywheel;

[preston240sx]

well my problem was i got sent a rb20de flywheel ... so my solution untill i get a rb20det flywheel was to use the ka24e clutch and flywheel that bolted right up no problems

[BoostFab]

cheap solution: D21 (nissan hardbody truck) flywheel will bolt on to the RB and you can use Z32 clutch on it. It's the same size as the RB's flywheel. you should be able to get the D21 flywheel from your local part store, if you dont mind the oem weight, but it's not too bad.

what year would that be found in ? also i'll probley end up getting a lightened flywheel gain alittle more power and quickness

lighten flywheel is nice, but you can't beat under $100 for an oem replacement flywheel. any 1991-1997 4cyl nissan d21(hardbody) pickup
