Need a new diff, what are my options
I blew my 1.6 LSD diff. I need a new one. Local junkyards have nothing, local sellers want $1,000+ for a 1.8 swap kit. Plenty of cheap 1.6 LSD diffs on UK eBay, but none of them are willing to ship to the states.
What are my options? How much should I expect to pay for a 1.8 swap? What ratio should I look for, or should I buy a 1.6 core for around $500?

The diff was making noises for a bit, and then they got louder, and then metal grinding noises. I only have a swapped 1.8 engine making 135/120 at the wheels. I do drive hard, I run dunlop zIII. lock and slide often. Sounds like normal use to me. I would have thought my clutch would have went first.
that $1k is a 3.90. is that what I want? do I need any other parts? probably besides bushings.

That is a healthy number, stock engine? Dyno?
If you are drifting a stock miata with Z3's in the rear you will definitely be breaking things, especially 1.6 things. For that power you should have plenty of grip with the typical 400tw tires people get for <$50. Make sure your rear alignment is good. a 1.8 swap is what you need, 4.1 or 4.3 for sure.

yes, that is the dyno results. bp4w with full intake and exhaust. i have no problem breaking traction when its a bit chilly. hard to on a hot summer day, so i dont often. alignment is good.
So I need to get a diff from a NB1, as that's the only 1.8 with a 4.30 ratio. What years does that cover, and did all manuals come with lsd for NB1?
pretty much all I found

Time to study up. There is a lot of info out there on this topic already.

Im thinking of picking this up here. its RHD subframe. I actually need a new control arm upfront, so I think I might as well buy the whole thing. Its from a year 2000 Miata, so thats a 4.30 right? otherwise everything is the same besides power steering right?

im gonna keep looking, but so far everyone with a rear kit wants 1000-1200 for it.
1500 for an entire rear subframe, and a front subframe shipped is a nice deal when compared. is it a direct bolt up? I get NB brakes and brace mounts as an upgrade. entire thing is rust free, i can clean and treat it all. probably has better bushings than mine, its lower mileage.
yeah, im gonna buy this the more I think about it. i got bad control arm upfront, and a mangled camber bolt hole.
