Is the clutch ca or cd specific? Could you let me know where you bought it?

No, the clutch is universal so you would have to modify your flywheel or make a new one.
I bought it via Erics performance.

Edit: You have to add material to the ID on the CA flywheel to make this work, but the CD flywheel has enough material and is more suited for this purpose.
I use cromoly flywheels because its safer.

What kind of splines do the discs have? How are you matching them to the transmission input shaft?

24x1, "standard" Nissan spline.
You order the discs with the spline you need.
What do you mean with matching the discs to the input shaft?

I thought the discs you get with it were some kind of "universal" as well. It's all clear, then.

I find it odd that you US guys dont seem to use these clutches more.
They are very popular over here and in motorsport internationally.

A $600 clutch plus a custom flywheel for 1arm+1leg may be hard to justify, when a $350-400 SPEC or ACT holding 500Nm's of torque is enough for 95% of the import mod people.

But 1200Nm holding capacity with streetability for just $600 is definitely a good deal, except the custom flywheel part.

How do you make your own flywheels? Put a 20"chromoly disc (is there such a thing?) on a lathe, and turn it down the way you want it, then hammer the starter ring on it? Is that your self-made one in that picture, with the clutch assembled?

Agreed regarding it being overkill for many projects, another thing is that people like bolt-on solutions.

I buy a 400x40mm disc of chromoly steel and get someone to make them.
If i should do it myself it would take alot of time and i dont have all the tools needed for a job like that.
This flywheel has machined starter gear, but the normal practice is to take it from a stock flywheel.
Modifying stock flywheels i do myself, thats alot less job.

pretty sweet build. I think I remember you guys talking about the diesel engine on here before. If we had them in the US I'd play around with it. A bit overkill but seems like fun. Good luck

Pistons?

I don't know, but I hope this "Holy Grail" of a CA some day runs and perform to your liking. I truly believe in pushing the envelope a tad bit, so I'm eager to see where you are going with this. I remember one of our members from Australia with the screen name "meminto" had one hell of a build that actually got assembled, but the fire appears to have been blown out or I have missed something along the way.

I was following Meminto's build as well, unfortunately life got in the way and he ended up parting out his vehicle. I heard that the engine ended up being sold for around $5000 to a guy with a datsun 1200 (not me unfortunately).

I agree, hopefully this build gets completed and used to the fullest.

He put so much love and devotion into it, but I completely understand about life. Hell, I have a very expensive and very well built CA18DET that I've never installed. It has solid lifters, Pauter rods, blah, blah, but it is not an essential for me at this time, so it just sits under a linen sheet in my garage. I'm struggling to finish the nissan sentra I'm working on now and it's due to my kids and my life and general, not the money as that is not the issue.

It`s for a torque plate :)
This project is going slow, but i am going to complete it.
I also have another CA18 project wich i would like to try with similar setup as the CD project.
Right now i am waiting for driveshaft and turbo so i can put my car together.

I started working on the honing plate, its somewhat time consuming with the equipment i have but it will get it ready soon.

I will have to use the holesaw from the other side also.
This is ofcourse only the first rough part, i will finish with the boring bar.

Looks nice!
I will be using this in both the CA and the CD.
Firstly the concrete CA since thats the one i have pistons for now.

The CD crank will not spin in the CA block without modification.
I dont see the point of not using the whole CD bottom but if somebody wants to know i have checked.

CD to the left, CA to the right:

question Ive been slowly building up a ca20de (ca20 bloc with ca18de head) thus far in my build i have toemi( im sure i spelled that wrong) valve springs kit and cams the head has be machined and im at the point where im close to mateing the head and engine. i have allready drilled and tap holes for the new head studs and i had the water jackets enlaged to match the head but i ran into a issue with the dohc timming tensioner find a way to mount it and the correct locaton to mount it but apon a close look at the spare block i had it looks like i would be drilling in to a water jacket so i had a coustom mounting plate made at a metal shop to keep from drilling to far in the block also from ealyer test fitting a honda p13 timming belt seems to be the right size it was able to match the crank spline pattern and cam gear pattern. But heres where im stuck i need cam covers and intake manifolds, exhuast manifold and also a way to set up the ignition system so my question is what are you using or how are you gona set up the ignition system keep in mind im going from dizzy to coils? And sorry for the run on sentnce im kinda writing this in a hurry cause im at work. Thanks :)

I am using a 24 tooth wheel on the crank and 1 tooth on the exhaust cam for synchronisation.
Not using the CAS.
Not sure what i will do with the coils now, going to testfit the VW/Audi COP`s thats so popular.

Finished my release mechanism:

Heres my release bearing mounted to the "adapter":

Needed to adjust the distance between the bearing and the clutch so i had to make a "shim":

The whole assembly:

Now i just need to drill holes for the lines and it will be ready to go.

Im a little uncertain about the engine mounts due to the massive girdle of the CD.
I don't understand this entirely.. could you clarify it for me, please?
Do the engine mounts fit, or not, in the end?
What do you mean by girdle? The cast ribs and webbings on the outside of the block to make it more rigid?

Have you also put the block with the engine mounts onto the front crossmember as well?

Just to make sure, by gearbox, do you mean a CA18DET RWD gearbox?

Thanks in advance!

No problem! Just ask if I'm not clear on something.
They fit the block but I am not certain if the engine has to be spaced up a little from the mounts due to the massive crank girdle.
I have not test fitted it on the cross member yet.

And yes I mean the rwd CA box.

I've always wondered about using a hydraulic TOB like that... How much did that run you? I've been thinking about doing something like that for my SR (I've never liked the stock lever setup)

The unit itself costs about $250.
I have welded the stock lever hole shut because i never inteded on using that setup.
