im planning on swapping the tII tranny in my n/a s4. while im in there im going to do the clutch. to me it would make sence to use the clutch for the n/a right? and is there anything else i would need to do (TII driveline, wiring, etc...) and i would need to get the tranny from a 86-88 right? i heard someone saying that the TII eccentric shaft has 23 splines and the n/a has 22, will the tranny even work?

im pretty sure you'll have to use a TII clutch and flywheel.



im not sure about the wiring. i cut all my wiring to my tranny though. didnt affect it at all.



but i have a TII motor and N/A tranny.

You have to switch :

clutch slave-cylinder

flywheel

clutch

driveshaft

startermotor



from a TII, I do not think i has to be from a S4, but not sure.



If you want to do it "proper" you should also switch the rear end from a TII, but you can get away with simply enlarging the holes in the mounting-flange on the driveshaft. I've done this, and it works fine on my car.

ok he beat me to it Ariel, never tired enlarging the bolt holes thats an interesting idea

lmao.



yea those wires dont do anything.



kevin.

ok, this sounds like a pain in the ass if you dont have the whole clip... later down the road im probably gonna do the whole TII swap, my buddy just has an extra tII trans layin around and i was thinking about tossing it in. can i get feedback from anyone who has used the TII trans with the n/a s4? my car only has 78k original miles on it, but the tranny is starting to make noise so i was gonna replace it. should i grab an n/a tranny you think? or is it worth it to get all the TII stuff? thanks i appreciate the info guys.

if your not making a lot of power, dont do it. n/a trannys are cheap. replace it only if it brakes.



most of the time when you buy a TII motor it comes with the tranny anyways. so you might just be wasting money.



this is just my opinion though.

If you are not planning on a lot more horsepower down the road, just find a na trans. It can be a lot of work sourcing and assembling all the right TII parts. I did it to mine because I want to put in a 13B bridgeport or 20B streetport at some point, and my clutch and slave cylinder needed replacing. Besides I wanted a lighter flywheel and they are easier to find for the turbo trans. Plus I already had the turbo trans and driveshaft lying around.



Hope this helps.

thanks for all the help, i think i'll just snag another n/a tranny.... are s4 and s5 n/a trannys the same?
