So I bought a 1.8 Housing and Im almost ready for my RX7 LSD
Alright guys, I purchased a 1.8 differential housing, driveshaft, and the half stubs and now im getting the rx7 lsd rebuilt and what not and getting ready for install. Quick question. Will my ring and pinion gear from my 1.6 open differential work with the 1.8 housing? and also Is it really worth it to change it to 3.9 ?

NA 1.8's had 4.10, NB 1.8's had 4.30 (some had 4.10 and 3.9), only the auto FC RX-7 had a 3.9 ratio, but you cannot use their pinion gear. The only way to get a 3.9 is either get one from a non-US 6 speed, or get a pinion gear from a late model 1st gen RX-7 with the short pinion gears (like an 85) and a ring gear from an auto FC.
