ok i have an s5 t2 motor that im going to be using na s4 rotors in. besides the front counterweight what else do i need? i cant use the s5 t2 flywheel can i? its a manual btw.

 

You need an s4 t2 flywheel.

 

can you mix s5 rotors with an s4 flywheel if you use the s4 counterweight?

 

i just had my s5 flywheel resurfaced. i thought it was an s4. anyone need a freshly resurfaced s5 turbo flywheel? i need an s4 t2 flywheel

 

i have an S4 TII flywheel as a matter of fact.
kevin will have my car here in a few days so maybe we could trade or something?

 

do you need an s5 flywheel?

 

yeah i have one, but
i could use a freshly resurfaced one

 

resurfacing itself was 50 alone. more than i thought

 

No, the S5 rotors MUST use the S5 counterweights. The S5 rotors weigh less.

 

actually the S5 Turbo rotors weigh the same as the S4 non-turbo rotors

 

then would i still need to get an s4 flywheel?

 

Mark, Im afraid you're wrong on this. s5 turbo and nonturbo rotors weigh the same...between 9.6 and 9.8lb (bearing installed). The s4 turbo and nonturbo rotors weigh the same, between 10.1 and 10.3 (bearing installed). I have a shelf full and a digital scale accurate to 1/100th of a lb...I took each 4 of each rotor and weighed them.

 

Hmmm.... I could have swore that the last S5 Turbo rotor I weighed was 9.8 and the last S4 non turbo rotor I weighed was 9.9

But it sounds like there is more than an ounce on your scale... and with your vast experience on that I'll go with your answer, ignore my last post in this thread.

 

Also, weights without bearings:
