S15 6 Speed Transmission for Dummies

[quadzilla]

Great info here guys. Im just curious why do you have to use the s15 flywheel when fitting the 6 speed to a non s15 sr20det?

I can understand the flywheel is thicker. Is the input shat on the 6 speed not long enough to work with the s14 flywheel?

Shot in the dark, but I want to say it is bc both the flywheel and bell housings overall diameter are larger and the matching flywheel is needed for trans, flywheel and starter to align.
