scroll about 1/10th of the way down..HUGE REFERENCE i came upon
As far as we know, every single 4 cylinder 200SX had 4.11 gears, no matter what. The whole 1984 CA18ET with 3.90 sounds fishy to me.
Only the v6 cars have a 3.90. The rest got the 4.111 weather it is an R180 or the R200 diff.
The CA18DET S12s in Japan had a 4.3 final. I noticed that in the CA18DET factory thread. The firewall code says RC43 which means a 4.3 final drive. And yes all 4 cylinder S12s in the US got the 4.11 which is RC41 on the firewall tag.
