scared...lol quick diff question
Ok, reading up it seems the 1.6 LSD sucks a nut? I just recently bought another 93 for a good price because it was a full option car with a hardtop w/defrost. It has LSD, but also has 220XXX miles on the chassis. I am turbo'd shooting for 230-250whp, so question is.....its gonna pop when I swap the diffs over aint it?

If you drive like my brother, yes. My mom, no. I ran on my 1.6 dif for 10K very hard miles but it only had 27K on it when I started turbo, no problems. But put a 1.8 in this winter just in case. Check the fluid for chunks and bring some oil dry stuff for the dragstrip, they'll appreciate it.

Anything can be fabbed up for anything. And while a Ford rearend might be necessary at the 400 ft/lbs level, I don't see the point in spending the time and money for a 200-250 ft/lbs car, when the 1.8 diffs are cheap, plentiful, and have a proven track record.

ok, thanks for the reply! Im trying to keep my options down, but it seens a 1.8lsd swap would be strongest for the buck? I dont do alot of driving as it is....maybe put 2000 miles on my miata a year, I dont drive like a ricer, but do plan on doing some drag racing....How weak REALLY is the 1.6 LSD compared to the 1.8? I mean, I dont plan on dragging the car 1000 passes or anything, it is my DD but like I said, I do plan on taking it to the track every once and a while.

Adding hp = cutting time.
I'm on my 2nd 1.6 differential. I blew the 1st one at 7psi on a lightly modded greddy kit (160 hp? No dyno numbers) after ~20k miles of turbo'ness.
Im on a 1.6 VLSD right now at 8psi, and I'm just waiting for the "roar/clanks" to appear again, and leave me in the middle of nowhere.
Just go buy a 1.6 diff, and let it hang in the garage untill you break the other one. This way, you'll have a way to get back on the road, and it'll save you some time to purchase a 1.8 Torsen.
700 - 900 for a bullet proof rear end (at least at the power you want) isn't too bad a deal, being that it just drops in (assuming you also bought the misc. ****)

i had two miata with the lsd rear end,
one was at 12 psi for 6 months of abuse, well, torture...
i mean bouncing rev and dumping clutch and poping into gears like it was my day job
the second i had turbo but didnt beat on it, seeing as it was my daily, but that one at 6 psi was fine for the past year
so i guess u either get gems like mine that havnt blown up
or u get a lemon

Yeah, but what's the point of having a high-powered car if you have to baby it around and are afraid to actually USE the power?
Borrowed time indeed. I'm on a 1.6 rear end, and as soon as time and money present themselves, I plan to swap it out ASAP.
Pretty much. That's why it's a common swap. Don't bother trying to reinvent the wheel. If you do decide to reinvent the wheel, though, be sure to vaguely post about it and build up suspense on as many forums as possible, then reveal something so incredibly stupid that you're laughed off of, well, as many forums as possible. I'd suggest something like retrofitting a rear from a Model T, possibly with a chain drive as well if you want to go this route.
That said, the 1.8 rear and LSD are desirable for different reasons. It's the larger (and stronger) ring and pinion, and differential in general that you're after with the 1.8 parts. The available Torsen LSD is one of the reasons that many adopt the 1.8 rear even if their power levels don't necessitate it. If strapped for cash, or just looking for strength on the cheap, one could get an open 1.8 rear and retrofit a Torsen LSD unit at some later time.

well i broke my first 1.6 drifting in a parking garage when my car was bone stock. like completely nothing done to it other then 60psi in the bald rear tires so it would spin.
iv been on my second 1.6 lsd for maybe 5 months now and have been making a lil more power then stock (115 instead of 93) its holding up but i can tell that the limited slip is not very limited lol. i have been wondering what the 1.8 diff will hold up to? can you break one with a stock motor 1.8? between 300 and 350hp.

lol static I predict one pass down the track and your Diff will explode esp if you have stick tires or some decent power to wheel hop. It is not a mileage thing its a strenght thing and the 1.6 gears and case are to small and weak to be effective period. Swap in a 1.8 diff and you can track all you want up to probly 300 hp when the torsens breack to fix this go with a RX7 clutch type lsd or aftermarket unit. And then you will be good until the halfshafts blow at 300 + hp.

If you keep the 1.6 rear, you could buy 2-3 spares really cheap for when they blow up. I got one for $60, just in case mine blows up before I can afford to get a 1.8 rear in it.
