hi guys! so heres there question, if i used a 13b and planned on using a different transmission with an adapter plate (or conversion plate whatever its called lol) what clutch and pressure plate would be used? would the clutch and preesure plate for a 13b be used or would the clutch and pressure plate thats supposed to go with the transmission supposed to be used?

 

Hi guys im planning on doing a trans swap for a project and i have an adapter plate for the trans but idk which clutch and pressure plate i should use, should i use the ones that corresponds to the engine or to the trans?

 

How about just a little bit of info so we have the slightest clue as to what you are doing?

For example, are you swapping a dual dizzy 10A into a 1934 Rolls Royce? Or a custom 4 rotor into a 1978 Lada? Or a V8 into a 2nd gen RX-7? Perhaps you are installing a Bell Jet-Ranger helicopter engine onto a Razor scooter?

 

It depends on if this other transmission would be usable with the stock flywheel. In most cases, it won't be (especially if you're needing an adapter), which means using a flywheel that will fit in the bell housing & allow the starter to engage. Another consideration is the need for a rear counterweight, which could be taken from an automatic FC.

The clutch and pressure plate must match the flywheel, but the flywheel must match the transmission.

 

Merged threads and changed the title to something useful.

 

not merged just posted in my own thread by accident and im doing a fwd rotary civic "bubble" or ef the thing is this was done previously by apg performance and they used a k24 trans off a acura rsx type S and i have an extra 13b block and im getting the trans from a friend for $150 with only 58k miles and i have an adapter plate for the trans which is done but now im stuck on what clutch pressure plate i should use along with the shift fork and clutch cylinders any idea for which the parts have to match with either with the 13b or rsx trans (k24)

 

once i know what to use i will post a thread with the swap process

 

You'll need to have it custom machined then.

The clutch and pressure plate will likely depend on your flywheel, and your flywheel will depend on your transmission and where the starter is located.

FYI, Mazda R type (TII) transmissions have a removable bellhousing, as do old school transmissions (RX-5 and below). That would probably be the place to start.

 

Hi JohnTurbo,

If you already have the K20/13B adapter plate done please share the info with me, so I can tell my machinist to hold manufacturing of the K20/13B plate. Whe are using the Flywheel from N350 S5 Rx-7 with Mazda Pressure Plate and 97-99 Honda Accord clutch disk. The Turbo II Flywheel is too big to fit. Go

Good luck with your project! PM me if you need to share more info.

 

Thanks for info aron about the bellhousing but i want to keep it fwd and i am having the adapter plate made for the 13b to bolt onto the. k24 trans i have seen it bolted together with my spare s4 block and it fits well we are just shaving the inside of the plate now to have enough clearance , if it gets too complicated i will get the bellhousing modded to fit the gearbox i will keep u guys posted

 

interesting info here, I'm new to the site as well as rx7, I plan on doing a stock trans swap and I'm doing as much research as possible before I start purchasing parts

 

how much do these adapter thingies usually run? I'm looking to mount a FD trans up to another Mazda engine, one with pistons though.

 

they are kind of expensive because you gotta go to the machine shop for them to make you one and idk how much is costs i got mine done for free because i know the owner of the local shop around here and he did it as a gift

 

I was wondering if you can tell me where i can find the adapter plates you used. The reason i am asking is because i am doing the same swap

 

Hola Camilo,

you have to use non Turbo 13B Flywheel, 96 Honda Accord Clutch Disk, Kennedy Engineering 13B/VW Adapter Spacer, Kennedy Engineering K20/VW Spacer and 86 Nissan Sentra Starter.

Bolt both adapters together at the VW common holes, then bolt to the 13B. The tricky part will be grinding and cutting the adapter and some of the K20 Bell housing lip to make room for the Sentra starter that will be mounted on top of the 13B -just like the 69-73 Rx-2, Rx-3 - old school style. Then align the clutch and bolt in the K20 transmission. You will use same clutch slave, throw up bearing etc. from the K20.
After that you got to customize the passenger side axles and curve the exhaust so it clears away from the axle shaft.
