hmm i was wondering this,

if i have a s5 TII motor and a S4 N/A trans what fly wheel would i use? my assumption is N/A flywheel with TII counter weight?

yes no maybe so?

any help would be lovely.

thanks.

You would want the S4 flywheel, but you'd need an aftermarket one, so you could use a S5 counterweight. BUT FC N/A tranny arent any better than ours. You really want a TII tranny.

you are going to need to run the na flywheel/clutch as well.. the TII stuff will not fit . (i found that out the hard way)

welp.. i have an FC N/A Tranny because i have a S4 6 port in my car right now using the S4 tranny i got with the motor.

and im to cheap/ dont realy have the money to spend on a TII tranny right now.. seeing an N/A tranny will do untill i realy need a new one. then i will get the TII trany.

any whoo.. back to my question at hand... why would i need to get an aftermarket flywheel? if its ment to fit an S4 wouldent it be the same as an S4 flywheel just made of a lighter materal.. and have holes in it?

and how about a S5 N/A tranny i saw one at the yard the other day.. i can pick it up for like $60 on half off day i think. if i had a S5 would that work? eh?

im clue less on this.. damn mazda... why cant they make it simple... and all have the same damn flywheel!

thats what i assumed.. thats good. i can still use the drag clutch i have in there then... but i need an aftermarket s4 N/A flywheel?

yes a light steel flywheel with a s4 counterweight is what you need!

81Rex6port13b

680... and might you have what i need at your shop?... im interested... seeing your not to far from me.. i can prolly take a trip and a visit.

680RWHP12A

mmmmmm, i have the counterweight... but racingbeat has the flywheel

81Rex6port13b

and one last thing just because im an idiot... and for clarity i need an S4 N/A aftermarket flywheel. and i have to use the S5 TII counter weight.

right?

just reassuring my self.

680RWHP12A

no you need the non turbo flywheel with the s4 conterweight

81Rex6port13b

ahhh gotcha.... Aftermarket Flywheel with S4 N/A Counterweight.

right-o

I thought the couterweight was supposed to match the rotating assembly of the engine, and the flywheel had to match the tranny. So with a s5 TII motor / s4 na trans you would need a counterweight from an automatic turbo (or an FD) and an aftermarket s4 na flywheel. Or am i confused?

if it is a s5 motor, then you do need the s5 automatic counterweight..

Yes you need the S5 auto counterweight with the S4 N/A light weight steel flywheel. As far as the tranny goes, what I was getting at was that the S4 N/A tranny is no better than the one that you allready have. Just use your current tranny. Dont make more work for yourself for no gain man.

jebus this is getting confusing... ok... so!

i need an aftermarket flywheel. steel or alum i assume. and an S5 TII auto counterweight?

im confused now... wich is it? lol

Makes no sence to buy a $300 flywheel for a n/a trans. Spend that 300 bucks on a T2 trans and be done with it.

^good advice

I dunno what 680 is thinking, but the counter weight is specific to the rotating assembly. More specifially what rotors your using. If you use S5 rotors in any combination 13b, you have to use a S5 counterweight. Plain and simple. If you have a S5 motor, then you need a S5 counterweight. The flywheel must match the transmission. It doesn't make a difference what engine its on so long as it isn't weighted like the stock one.

81Rex6port13b

ahhh gotcha... makes scence.

thanks

s4 goes with s4
s5 gos with s5

all these letters and codes , sometimes i get confused!

81Rex6port13b

thanks for the help
