350z clutch in kade-t

Post by **kazuma** » Fri Sep 04, 2009 6:11 am

Hi I was wondering when using a 350z clutch with a rb20 flywheel are we suppose to use a 350z throw out bearing or a regular 240sx throw out bearing?

Thank you.

Ask whoever sells the kits, SPEC, AMS,

but I would think you'd use the 240's, since it still has to hook up to the stock trans

well I contacted competition clutch who uses a 350z pressure plate with a 240sx clutch disk on their setup and they use a 240 TOB.

The reason I have been looking this up is because i have been using a 350z TOB and it lets me shift fine but after a bit of driving the clutch over heats! I have a brand new clutch in there with less than 40 miles on it and I think I know what my issue is now.

f*** I should've asked about this before putting everything back together. now I gotta take it off again and spend another 50bucks(Canadian) on redline MT90 fluid!

Help me here...Are you bolting it up without modification? What all did you use?How much Wheel power is that setup expected to hold?

I bought a rb20 flywheel for 30 bucks used off a guy in town. then I ordered a dxd clutch stage 1 for the 350z for 350 and it can hold 433tq! so my total cost is about 400 bucks(20 for a 240sx TOB).

it fits without any modification to your car as long as you have the rb20 flywheel.

That sucks... Have you tried adjusting the clutch master rod? It might be constantly engaged, causing that. Try that before you go pulling the trans

That's pretty dang effective...I wonder what the stock 350z clutch holds.?.?.?

O....M....F....G

YOU ARE MY LIFE SAVIOR!!!!

I did the adjustment and it fixed it! no more slippage at all!!!!!!

if you were here I'd buy you a nice big a** steak lunch

.

Thanks again for your help!

btw the stock 350z clutch holds about 280ft/tq which is a lot for our cars already but for like 50 bucks more you can get the clutch I got from dxd clutch and it handles 433 ft/tq!

Haha funny thing, we just got back from eating steak for my bro's bday, but I'm glad you got it sorted out!!

So this also confirms that a 350z tob will fit the stock trans!

ya so far so good, cant rev past 3k yet since the clutch is being broken in but cant wait for the 500 miles to be over so I can get on it a bit

.

so to get this setup you will need:

1.rb20 flywheel(or something exactly like it

)2. 350z clutch kit with TOB3. install and have fun!

just wanted to give an update! my issue was not the adjustment of the clutch pedal but the stupid dampening box!!! after I adjusted the pedal it helped a bit but not much so I had to adjust it back and removed the dampening box!

dampening box = biggest pain in the a**! my clutch actually feels software without it in place!

Maybe I'm reading into it too much... Is there another flywheel that will work?

Well I'd think any flywheel that would be compatible with a rb20/rb25/early rb26's would work in this setup as well.

Did you use the 350z disc, or a 240 disc?

clutch disc, pressure plate and throw out bearing are from a 350z.

nothing from a 240sx is used really besides the pilot bearing since its specific to tranny/crank.

just a heads up for people who want to do this. make SURE the clutch kit you buy can be installed on a stock 350z flywheel! before I got my dxd clutch I had bought a RPS clutch kit which DID NOT fit on a stock 350z flywheel, hence not fitting on the rb20/25 flywheel.

oh and just a bit of update, clutch is amazing! engages near the top of the pedal engagement and feels very strong! cant wait till I get tuned.

Post by **Jables** » Wed Sep 23, 2009 4:54 pm

Just a note the pilot and throw out bearing are all the same for most the popular swaps. The SR, RB ( push style or RB26 with RB25 trans ), KA all utilize the same pilot and tob. I've only seen a couple of cases where someones quill was a little bigger or smaller and i had to use another similar bearing with a different I.D. ( inner diameter )..

If you ever need info or have questions feel free to hit me up.. And yes those dampening boxes are a PITA .. Glad you got it figured out!

Bringing this back.

I'm going to be using the RB20 Flywheel and 350z clutch setup. Just wanted to talk to the guys who actually did it.

I can get a stock RB20 Flywheel for 60 bucks to my door. Not sure if I have to resurface it or not.. (probably)

OR.... I can go out on a limb here, and try the eBay lightweight RB20 flywheels for 180-210 shipped to my door.... Opinions?

And, I'm in touch with F1/ Speed Solution International. Whom of which I ordered my KA lightweight Flywheel and ACT Extreme clutch from back in the day. (no issues with either) They have a 350z 'in house' clutch that holds 450 wheel torque (280 bucks), or an ACT setup that holds 560 wheel torque (450 bucks).. But don't offer a flywheel..

Anyways, what are some of your opinions? I like to get feedback on who has used what parts... But me as always, likes to try and find other options so that we can have real world feedback on some of the stuff people are sketchy about using.... (sometimes it scares me)

The reason for the upgrade, is a potential upgrade to a straight TO4R. But regardless, I'm going for E85 and some 1600cc injectors on my 3076R and I want to max out the turbo.

Anyways, feedback my minions. Discuss!!

If you can get a rb20 flywheel for 60, i'd say go for that, save that $ towards the clutch. Second choice of course is to try out an ebay flywheel...

Now, FWIW, I think the best single plate combo would be the ACT 6 Puck w/ HD PP, it's rated 582 crank torque.

If they offer an Extreme PP, I wouldn't go for it, it seems such a high clamp load makes them prone to lock out on high rpms shifts..

Post by **eazye2000** » Mon Apr 12, 2010 4:37 pm

^ I hear ya man. I went to order the ACT setup today, and they don't have all the parts in stock. So I'm going to wait for them to call me and see what's up.

Tomorrow, I'm going to call SPEC, and Competition Clutch to see what they have to offer in the 350z flavor, and see what the prices are. I saw that old dude above my post is a vendor here on the site, so I'm gonna call them.

I'll post up my own thread, with pics and installation steps for a good write up on how all this stuff works. I think I'm going to get both flywheels and see which one I like better. Or just to have a spare..

spec steel flywheel (part #sn42s) is made for a ka and can fit up to a 254mm sr20 clutch acording to they guys at spec. i got that and a spec 350z stage 3 plus clutch kit. havent had the chance to see if the 350z presure plate and clutch fit corectly but the guys at spec asured me that they would. if not ill just send it back and get an rb20 one.

the question i have is will this all match up with my z32 trans when i get to that point, god i hope so.

The 350Z plate does bolt to it, however the plate is not a perfect match. You may have to clearance some holes in order to make it fit just perfect.

The Z32 trans is still a 24 x 1 spline input shaft so yes they are both the same!!!

Hope this helps!!!!!

thanks for the info man. relived to hear its guna work.

also has anyone ever tryed an sr20 clutch in 254mm? i have no idea if this would work but its an extra 4mm of contact area over the 350z.

Post by **Jables** » Tue Apr 13, 2010 8:51 am

The 350z clutch is the 254mm upgrade. The SR is the 240mm.

Post by **eazye2000** » Tue Apr 13, 2010 9:56 am

I'm glad to see people have interest in this.

One thing you guys should know, is that Justin at SPEC carries everything needed to do a considerable upgrade over stock. They use a dual pattern flywheel first off. It has a pattern for the stock KA clutch, and also an SR clutch. Very nice for that time you blow your ish', and can only afford a stocker to replace it with.. And as said before, it's only 240mm as compared to the 350z's 250+mm disc.With that said, they have an SR clutch that is capable to hold 685 pounds of torque, in a single disc setup. This is for the KA.

Money is tight right now, being that I'm picking up a 300zx transmission (Z32). That is up in the air about swapping in right now.

It's either a super clutch to hold the power, but potentially blow up my stock KA transmission... lol...OR swap in the 300zx tranny, and hold out for a good clutch....OR put in the good clutch, and save for the z32 swap.Either way, a Z32 tranny will bolt right up to any of the aforementioned clutch setups for our cars. Pending you have the adapter plate for the Z32 trans.

Sorry for the book, just putting the info out there.

That is part # SN333-2 which is the 350z 254mm clutch. The only other clutch besides the SN54 series that fits with OUR flywheel is the SN33 series which is the 240mm SR clutch.

Hope this clears things up..

thanks man, i guess i already have that disc lol.

Post by **Jables** » Tue Apr 13, 2010 10:41 am

If you are second guessing yourself now just measure the disk diameter.. That should tell you everything.. or you can email pics of the plate and ill tell you what you have for sure!!!
