Only meeeee
How do I know if I have a 100 or 120, all the writing on the plastic end cap is worn off. I am assuming the 100 is slimmer? If so does anyone have the measurement from pulley to other end?
Or do they look different to each other, if so any pics?
Feeling like such a newbie at the mo.

I'm on the iPhone at the moment so a pain in the arse to surf as easy but I found all my info on the z22se forum with regards to the alternator. Some indications would be 100A has torx bolts and interlocking pieces on the frame. But it's not conclusive. There are some measurements you can make too which the pics are on the z22se forum too. Are you supercharging or 2.4 manifold? The how too on the 2.4 is all there too.

Cheers Noodle, think I am going to have to order a 100amp, pic above is 100amp (from link)
strangely mine measures 17.5mm to edge of basket so would think it's already 100, but instead of measuring 40mm to outer edge (like pic), mine measures 46mm.
Weird!

All a waste of time, still got the old Courtenays sc setup with piggy back ecu, so the extra injector is making it impossible to fit either alternator, not got the patience to remove inlet mani and plug em up + getting base map sent from Courtenays blah blah etc etc.
Going to flat bed it there, prob end up with loads more go faster goodies, just so it can sit in the garage for a few more years.
