Clutch SOLUTION!!!

[McAdam]

hello all,

well I have been seeing the lengths people will go to on this forum for a performance clutch (SR flywheels, dremeling KA clutches) I beleive I have found a solution..... HI Perf clutch I know the title says 240 to 280z, but if you read in the description, it says it will also fit the 200sx's with the CA20E AND the CA18ET. correct me if I am wrong, but dont the CA20E and CA18ET stock clutches bolt on to the CA18DET flywheel? Hi perf clutches for the 240Z, 260Z, and 280Z 2 seaters (225mm) are EVERYWHERE, and reasonably priced

CHeers, McAdam

It says AITA Clutches INC. Are the clutches made on site or does some other company make them?

[McAdam]

I dunno, i was just using it as a reference for the interchangeability. but still, thats not a bad price fora 4 puck cerametallic.

I wrote some one about using the 240ZX and 280ZX and 280ZX Turbo clutches as they were 225mm like the CA18, no answer, let me look around in me email and bookmarks,

[McAdam]

280zx turbo clutches are 240mm, as are the 2 + 2 models. All 2 seaters are 225mm tho. as you are aware, I have a ca18ET block and crank and I am using a CA16DE head, so i kind of have a CA18DET, but not really? but i have the CA18ET flywheel, so i can use that performance clutch. we shall see..

Enjuku Racing can get you SPEC clutches made for the CA. I am not sure if the FWD CA clutch would work with the RWD flywheel.

[ca18datsun510]

the discs are interchangeable, but the pressure plates are not. the only pressure plate i have been able to find that fits the rwd ca18det flywheel is the one from a late 86-87 stanza with the ca motor. i work at a parts store and have brought my flywheel in and tested a lot of setups.

waitso if im going to take my clutch off my CA18DET transmission (manual) and put it in my CA20E engine transmission(manual) they wont bolt up the same? lemme know what i need to get for the 2 clutches to work. thanks.

[YellowPreludeR]

im going to be taking the bell housing and crap apart tomorrow, so lemme know if i should do that or not ???

[drumma022]

I would have to say that a CA20 and a CA18 flywheel are different design. I am not sure on the pressure plate bolts/dowel pins, but IIRC the CA20 has a 6 bolt flywheel and the CA18 has an 8 bolt flywheel. (That is why when you try to put a CA20 crank into the CA18, you will have to find a new flywheel.) Since Nissan took the time changing that side of the flywheel, I am fairly sure that they also decided to change the pressure plate reallignment.

After tyoing all this, I checked at some of the replies, and if the stanza had the CA20, then ca18datsun510 would be saying that the CA20 pressure plate will bolt up.

Sorry to add to the confusion

[YellowPreludeR]

so what do i need? can i use the stuff off the ca18 or am i going to have to get a whole new clutch assembly for my CA20 transmission? cause the ca18 is like brand new...under 10k miles on it and i would really like to save it if possible.

[McAdam]

CA20 and CA18ET are of the same design I beleive. I have the CA18ET block and crank, and the flywheel is six bolt. Nissan Motortsports lists a clutch for the CA18ET and CA20E in the S12 200sx and it is the same clutch for both motors. gobblde-gook. lost in a quagmire of nissan parts and numbers.

McAdam

P.S. only reason I thought it would work for CA18DET motors was because I read a few times that people are getting CA18ET clutches for stock replacements on their CA18DET's.

[YellowPreludeR]

so from my CA18ET to my CA20E(T) soon to be Turbo, i can change the clutches and crap out ok?

[ca18datsun510]

the stanza has a front wheel drive ca20, different flywheel than rear wheel drive. the fwd ca20 has the same crank bolt pattern as the rws ca20/ca18et, but the pressure plate setup is the same as the rwd ca18det, it sounds complicated, but its not. i say just go to an australian web site and order a clutch for a silvia with a ca, since the are as common as 240sx's are around here. there dollar is weak right now, so that equal's out to a good price anyway.

[drumma022]

The RWD CA18det has an 8-bolt like the SR. The CA20det flywheel is 6-bolt like the RB. The FWD CA18de from the pulsar has an 8-bolt (according to Nissan).

This is all off-topic here. What matters is the pressure plate design for each of the motors. If they are all about the same, then I have an old pressure plate laying around with the 4-puck unsprung disk. I was going to send it to SPEC to develop a kit for the CA, but our supplier said they have already done so.

[YellowPreludeR]

thats still confusing me. both my CA18ET and CA20E are RWD and probally use the same setup, im just unsure till i get my chiltons manual.

this is on topic. they dont have the same pressure plate bolt pattern/dowl pattern as the det. the sohc flywheel and dohc flywheel are not interchangeable. the fwd drive flywheel is not inter changeable. the pressure plates patterns are different, the crank patterns are different.

THE CA20 FRONT WHEEL DRIVE PRESSURE PLATE HAS THE SAME BOLT PATTERN AS THE CA18DET. THE CRANK BOLT PATTERN IS DIFFERENT. THE SOHC CAM REAR WHEEL DRIVE MOTORS HAVE A COMPLETELY DIFFERENT FLYWHEEL. WHY IS THAT SO HARD TO UNDERSTAND?

thank you.
