Does the 20B bolt up to the s5 NA tranny?

change the fly wheel, and yes.

turbo II tranny is cheap and holds more power than the NA, i don't think thats an area you want to cut corners

every 74-02 rotary has the same bellhousing bolt pattern, except the automatique fd and the cosmo's, but it still works

So i can just use my flywheel but do I need a couterweight or anything?

you need an aftermarket flywheel, there is no 20b manual flywheel

what did he 20b come stock in? and why the choice of no manual?



kevin.

It only came in the latest and last version of the Cosmo. All were automatics - ALL. It's a large upscale luxury cruising missile, not a sports car.

If your putting the 20b into a second gen RX you need to use and upgraded flywheel for either a T2 or the stock fd flywheel..but you must use an after market clutch for a T2 try an exedy hyper single they are good...and you can use the stock counter weight from the 20b..

where can you get the exedy clutches?
