I've two RX-7's. One is a spec7, so it's gotta have either the open diff (Ummm no.) or the GSL diff (
)...The other is gonna be the nutcase street car. See sig as to what's going in it.
I forget who's running a hybrid GSL-SE engine with S5 N/A housings, but I believe they got over 200 HP outta that setup. I think that'll do nicely with the 4.3 gears and Torsen.

EDIT: i like to drift and drag...so i need a setup that will keep these things and still be driveable!

why do you say the 8.8 is not drift friendly? its is a solid axle just like the stock rearend its only stronger. and a little more weight...if you get it cut down to the stock specs then i see no reason why it would be "not very drift frendley" as you say
can you plz give more info as to why you say this?

One thing to know is that the Miata Torsen is going to be break happy at anything over 250whp. I know miata guys who will not run them with sticky tires and anything close to 200whp. Torsen diffs are not as strong as LSD's. So for clarification I can sawp a FC LSD with my gears into my 84 housing and the axles will pop right in??

The nature of the stock clutch LSD makes it grip harder,the more HP you pump into it.Even when worn out or lacking preload,they will hook up when the power kicks in,its just how they work.They cab be treacherous too due to lockup under decel and chatter when driving normally.But they are far more robust than the complex Torsen type LSD.
No such thing as an 83 SE....84-85 only.
All the 84-85 cars had bigger axles,so no its not a direct swap.You can do it,but youll have to rebuild the diff with 84-85 side gears,hardly worth it.
If you are talking about an 83 LE,then yes you can swap the 82 GSL pumpkin right in.Youll need to run the 82 driveshaft or change the flange to match the 83's driveline.

78-83 small axles
84-85 big axles
78-82 large pinnion flange
83-85 small pinion flange
Incase you don't know the flange is what bolts the drive shaft to the rear end.

Ok guys, while we're at it.. I have an 85 SE and I will be doing alot of drag racing, I also have the 13b turbo engine and tranny, and plan to use drag radials and mabye even slicks..I'm not at the point that I want a new rear, but I want something that will hold up..I really, really need to do something about my LSD, it feels like an open diff..What would be my cheapest and easiest solution..Sorry for the hijack
