-Track oriented street car, minimal street driving in the summer (1-2days/week tops + to/from events).
-RS3-V2/NT01/RE-71R grip levels.
-End goal is 170ish whp.
-Street manners not crucial.
-6 speed but I'm not picky about gearing.
1. Torsen (3.9/4.1/4.3)
-$650-$900 + shipping to Canada through the various forums. More $ through a reputable vendor. i.e Treasurecoastmiata
-40,000-150,000+ miles.
2. Maruha Clutch Type 2-way LSD - http://chikaramotor.com/catalog/prod...ype-lsd-2-way/
-$800

That's a built diff or are you setting it up yourself? If you're getting it built, how much extra do you think that's going to cost? It cost me $400 to get a diff setup next day.
What are you asking, do you just want validation for going and getting a Maruha?
Just flip a coin. If you're worried about wheel hop and the torsen acting like an open diff, then just get the clutch. You're not going to have enough power to break the torsen so just start driving already.

By my last post, I meant that I wouldn't be able to shell any money towards seat time with a Torsen than I would with a Maruha.
If I find a Torsen in a carrier, I may give it a go. Otherwise a shop will be setting up either the new Marhuha LSD or used Torsen.
Just trying to gauge what seems like a better option given the fact that the price is pretty much the same for either LSD.

Depends on the seller, there are quite a few in that price range with the housing but there's also 2 recent posts in the marketplace section for about $700shipped with no housing, axles or driveshaft. Shipping to Canada isn't cheap and driving down to the border to pick it up will likely cost just as much in the end.
This vendor isn't local to me (but is reputable) so I would have to drive 9-10 hrs but the cost to set it up and install seems very fair and I won't be able to find that locally.

Kind of, to me it seems less risky than buying a Torsen with unknown mileage/condition, especially if the price is similar in the end.
But that's why I posted this poll. Maybe I need to rethink my analogy.

You could always do an RX-7 clutch type diff if money is that tight. I have like 5 or 6 hours and $275 in mine. You will have to shim it if you want more dynamic lock but they are pretty much indestructible and you can buy new steels and clutches for them oversize from mazdatrix ($$$).
Can't take your poll as I have never used either of the options you have listed.

There's the mfactory. Pretty much untested in the miata fitment. But they're great in everything else, their clutch type design is on par or better than OSG. Tuning is unknown but they're going to be substantially easier to deal with than Jonathan "I'm going to argue the wrong side of a physics argument with someone who is a Physicist" Ludgod at OSG to get your tuning changed.

Gotta love it when people ask something and then do the complete opposite of the advice/poll response given. ![facepalm](https://www.miataturbo.net/images/smilies/facepalm.gif)
I guess I just can't justify taking the risk of spending $800 USD on a high mileage Torsen in unknown condition when I can get a brand new, albeit 2 way clutch type LSD for the same $.
Based on the experiences of a few people I've spoken with, I am likely gonna go with the _ _ _ _ _ _.

I didn't even know the Maruha existed before this thread.
Another one I just learned about recently (via non-miata people speaking highly of it) is the Kaaz Super-Q. It's supposedly very comparable to a Giken. Again, I haven't heard of anyone using it in a miata, but it's in the price range you're talking about. I'd probably buy it before the Maruha.
I think this is the right part number but you should confirm before buying.

2 way is too aggressive with decel lockup. 1.5way is what you'd want.
Dont forget that $800 lsd needs $100 worth of measuring tools to install and basic reading ability and tool use or paying a shop $400 to install. Where that $800 better be in a rust free housing and low miles to be worth $800. If its just a loose used torsen I wouldnt pay more than $300 for one.
