Errr, just look at the Wikipedia article on Toyota C transmissions.
The 1991-1998 Corollas are 3.722 apparently, but the 1ZZ powered Corollas are 3.941 and up. I don't know if the C50 bolts straight to the 1ZZ, I'd be safe and just get a transmission mated to a 1ZZ. You'll have better acceleration anyways.
Good to hear your 1ZZ doesn't burn oil, so many of the early 1ZZs do. I'm on 10W-30 dino oil, I am going to try 5W-20 next time and see if it's any worse because I make so many short trips. You're also "lucky" that you have FWD so no need to modify the transmission to make it work
Good luck with the swap, and hope you get those nice low revs
I would love to have the Corolla ratios in this thing, or at least just the 0.725 5th.
