the reason why i ask is because my flywheel is still stuck in thier and to me it doesnt seem like the fidanza flywheel will fit...the center whole seems alot bigger than the stcok oness...will it fit or...? the paper says to use stock counter wieght and i dont see anything else there beside the nut...?

 

If I do go ahead with my rebuild I will be using a Fidanza. I called a couple of performance shops in my area that deal only with rotaries and they said that the Fidnza will fit perfectly. Thats about the only help i can contribute.

 

oo0o really... i'll just wait untill i pull the stock flywheel off and see....im just very curious about it..anybody using fidanza flywheel right now?

 

Well, no crap the center hole is bigger than the stock one! You have to bolt the automatic counterweight to it!

That's why aftermarket flywheels are often so cheap... because they leave out the 120-dollar part you have to buy to use it.

 

R U Serious? I Thought It Would Have It In Their I Guess Not....

 

Yeah, you'll need to pick up a counterweight. They can be had from $50 to $150 on this site, e-bay, and various vendors sell them.

 

so i need the automatic counter wieght? ima just go to the junk yard first thing tomorrow and hope they would have it...

 

You do need to get one from the same series as your car.

86-88 = S4
89-91 = S5

Turbo/NA doesn't matter, just the same series.

Looks like this.

 

i got an s5 y cant i get the s4 counter wieght? just curious

 

i got an s5. y cant i get a s4 counterweight? just curious

 

The internal components of S4 and S5 motors are different weights.

Essentially the "weight" that it is "countering" is different, hence, different counterweight.

S5 rotors are lighter, and higher compression btw.

 

thanx for the heads up.... i appreciated that

 

I sell the fidanza flywheels and plan to use one myself I think they would make a GREAT compliment to a nice running sporty n/a

I will check but I may have a spare s5 counter weight

 

o0o really do you.. but im pretty sure i can get one but if cant i'll come to you thanks for the help....

 

im thinking about buying an act counterweight..but does it matter if im using an act couunterweight on the fidanza flywheel or does it has to be an act flywheel?

 

> It's the same thing. Just depends on the year.
