thanks everyone! Makes me feel better. I got a quote from a miata specialist and it was 1.5k to upgrade to a 1.8, that included everything.

I spent $250 on a complete torsen assembly from a local junkyard, $100 on axles, and $50 for a driveshaft.
then i sold the stock parts for $300. So 90% less than you suggested it will cost.
Did you swap it yourself? If so, was it easy? I dont know if I could do it.

lol! Sounds like you guys have been lucky.

If it's street-driven responsibly, 200whp is no big deal. But 200whp drifting and doing drag-launches spells trouble... especially if there's some decent rubber out there.
I put about 100k miles on a 1.6 dif between 180-220whp and was what I would call "street abusive"... but no drifting or clutch-drop launches. And that was all on 195series Toyos T1S/T1R, so not too sticky, but not stock either.
Tell us more about the car, link the ad, post pics, put up a build list... making a buying decision on a 100% dead-easy cheap repair/replace item doesn't make sense to me.
Im not sure how much whp its on. I dont think the guy has abused it (drifting, clutch drops) but I do think he has driven fast on the roads. I only have got one quote for a 1.8 rear end and everything came to $1.5k. I have the money to do it immediately so if it went its not terrible. The last car I bought ended up needing 3.5k in repairs and needed new tires so Im very worried it will happen again. I guess my main concern was that I would have to change it immediately and possible have some other issues but it seems I could get away with it for a bit longer. I think I'll have it inspected and if its in good condition I'll buy it.
