ok so I've been doing some reasearch on doing a complete swap from a 7mge to a 7mgte with the r154. i see that the rear differential is different from the late 80's and early 90's. Is it necessary to also swap rear differentials?

About the only major difference are the ratios.

Seeing that you are NA now, I am guessing you have the 4.3 ratio gears,
but a check of your car's build tag will give a trans/axle code, I can tell you exactly what you have.

Most of the later turbo cars had a 3.7 ratio.
Some people like them to limit wheel spin off the line.
Personally, I like to put enough tire on a car to do that.
I run 4.56 gears on the street, and 5.29 gears for the strip, but I run an automatic.
A 5-speed does not require ultra deep gears like that.
