Wow, thanks for everyones input! Sooo I'm feeling a lack of love for this setup, is that because it's not the "classic" setup?
Nah just buggin! I totally agree with everyone on the fact that this isn't the "best" or even a "great" setup but it's all I have and it's free which is unfortunately the major factor.
As for LSD, the '85 GSL-SE model did indeed (North American version??) come with a stock LSD and from what I've read (Note: read) there's plenty of 1st gen drag cars that run the stock rear axle and LSD in both the rotary and piston converted rex's quite well.
As for swappability, I've got a kit already and there's plenty of support and not many modifications required to drop it in. The engine itself is heavily supported by aftermarket and far more within my level of knowledge and skill than a rotary engine. Lastly, even with the swap it's a pretty decent weight at less 3000 lbs with driver and gas included.
Lastly, frick the police! lol, nah I have an 07' Mitsu Galant Ralliart as my daily and the rex will be track use only.
Anyways, now I probably sound like a dink or maybe I'm just trying to make myself feel better about my setup, rofl! But I seriously do appreciate the responses and would love to hear any and all other thoughts!!
