clutch

[burnout 180]

I really need a new clutch but i need some help because i don't know which one to get. What clutch do you have and what do you feel is a good clutch model/brand and where to order it. i can't make a decision because i could go with a sr clutch and change the starter gear or a ka clutch and do some modification or find a ca clutch and this is my first time ever having to buy a clutch so i am kinda lost.

First off, in order to use the sr20 clutch - you will need to use the sr20 flywheel, sr20 clutch, grind off the couple spots on the bellhousing that hit the sr flywheel, and use the older 200sx starter. For a ka clutch - you will need to remove one of the dowel pins on the flywheel I believe. Or as you said - just find a ca18det clutch (which is not the same as the ca18de fwd clutch). Jgy, and a few other companies have actual ca18 clutches available. This has all been covered before - but thats just a quick refresher.

I'm using an oem replacement Dynapak clutch/pressure plate for a ca18et on my engine. Fits on w/o any problems. All the dowels line up.

If you're looking for a better clutch and pressure plate. Centerforce makes a dual friction clutch kit for that motor.

You're on your own for a flywheel though. The ca18et one won't fit(different bolt pattern).

(the ca18et is for a '84-'86 200sx 1.8 turbo)

KA24de i perfer RPS,ACT,Spec although this year we have had a few to many spec failures... i have a stage3 4puck and i love it. next will be a RPS

[burnout 180]

I know. I have seen the post on how to get a sr or ka clutch to work. i just wanted to see what clutches others were using and there experiance.

Also hopefullly i can get some recommened web sites that i could order from.

No offense, but we all know how to use the internet. A simple search with a search engine will yield you links to all of the afore mentioned websites. I don't really think it's fair for people to not only give you brand names, but to look up the website AND create a hyperlink for you so that you won't have to type it into google/msn/yahoo.

Im using an Exedy stage 1 clutch for the ka24de on mine. Just removed one of the dowel pins and everything lined up perfectly. Bought it off of ebay. Been running three years no problems.

[burnout 180]

i was thinking of going with a ka24de clutch also because there seems to be alot of good kits for resonable prices. Was moving the dowel pin easy to do by your self or did you take it some where to get done? i'm between getting a ca or ka clutch because i know that i'm not going to go with the sr clutch because getting it to work seems to be kinda extensive.

I'm using a Centerforce Dual Friction on mine and I love it. PDM Racing seems to like them too. And they aren't that expensive and will hold 300+ ft-lbs. Plus, they feel like a stock clutch...just a tad grabbier.

[r34 gtr]

just found out toda makes a 3-puck metal clutch for the ca18. check it out (its under the sr20 section). when mine goes out (probably never) ill be picking up one of those for sure.

[ca18hatch]

Removing the dowel pin was quite easy...I just used a pair of vice gripsand pulled it out. I personally would recommend going with the KA clutch since they are quite a bit cheaper and easier to find.

[float_6969]

I'm running a SPEC Stage III clutch right now and it holds well, but I don't like the pedal feel. VERY light. I intend on running the CFDF when the SPEC goes.

i had one is well, but on a ka.

well actually 3 ka's, i kept throwning rods, but the damn clutch was perfect everytime. it was still on the car when i sold it, and i never had a complaint.

[burnout 180]

i read up on Centerforce Dual Friction clutches and i think i'm going to get a ka one now also. I used to think that moving the dowel pin would mess up the balancing of the clutch exspecially how they use a unique system of weights that can slide in and out to increase clamping pressurer without increasing pedal effort. but no one has seemed to have a problem and removing it sounds easy so i'm going with them.

i also i want a light flywheel does the ka one work also?

IIRC, no. Different crank flange etc. I may be wrong?

[float_6969]

NO, the KA flywheel won't work. AFAIK, there aren't any US company's that make a flywheel for the CA, so you'll have to get one from Japan. Be prepared to pay out the butt and wait a long time. Sometimes they'll pop up on eBay (that's how i got mine) but you'll have to be patient.

If you're worried about weight balance, remove all 3 alignment pins.

[burnout 180]

no i'm not worried because no one else has had a problem so obviously moving that pin doesn't make a great difference.

I just read an old post that said the same thing i thought that maybe someone may have started making a flywheel that will work for the ca. i guess i'll have to see if i can find a JUN flywheel on ebay like you did hopefully i can get one.

[float_6969]

You can run an SR20 flywheel, but you've got to use an SR clutch, grind down the bell housing where it rubs, and get a Hitachi gear reduction starter from an S12 w/the CA18E(T).

Guys, Why can't you just get an ACT clutch set for the KA24DE and only modify the dowel hole in the pressure plate??

We have been doing that on CA's for many years and no failure what so ever.

It makes me sick just thinking about you guys pulling out/eliminating the dowels.Dowels are there for a reason.

Guys,

RYSO.

they are there to help line up the pressure plate and hold it while you put in the bolts. once the bolts are in it doesnt make a ****s difference.

[r34 gtr]

no one bites on the toda one? i mean, its bad a$s and it doesnt require any modification. sorry, but im lazy!

[1fast200]

DUDE, you don't know what you are talking about nor you have the minor idea who you are talking to.

DOWELS are there for a reason, if you want, go ahead and take yours out, I'll leave mine and my customer's in.

I'm out...........

RYSO.

[ca18datsun510]

dude, dowels are like totally for alignment brah.

we're not spinning a 7,000 horsepower top fule dragster motors here.

you have no idea who you are talking to either.

even farther then that i dont care who im talking too.

Ever wonder why people have their machine shop add dowels?? Ohh yeah, they are only for alignment......

Did you ever see a motor snap all bolts, just because the dowels weren't were they needed to be??Ohh no, you couldn't experience one because you are running no dowels and still didn't break any bolts, that explains it all, your not making power...

Just don't forget to pull out the dowels on your next clutch swap (buraku di atras).

RYSO.

[ca18datsun510]

i dont recall anyone saying to remove all the dowels. just one is not going to make a big difference on the average ca enthusiats 250 crank horsepower motor.

if anyone was making enough power where it would make a difference, i doubt they would still be running a stock flywheel setup anyway.

get real.

edit, after reading my first post i see what you are saying, but if you posted here more you would know that a lot of my posts have a "tad" bit of sarcasm in them. i shouldn t have said anything about the bolts, thats a bit misleading to anyone who doesnt know.

[mbmbmb23]

Just drill an extra hole in your pressure place to accomodate the dowel. Easy peasy Japaneasy.

For the guy who wants the clutch advice, I would get the Centerforce Dual Friction. I have a sneaking suspiction the CA18ET unit bolts up....I could swear I researched that before.
