gospeed sells it, but it's much cheaper from some sources on ebay...it's much more expensive that it was when i got it for around $175 shipped.

I'm also wondering why the 180hp limit? Fueling? The stock 1.8 engine is good for ~250 without a problem and while a 2860 isn't the turbo I would choose to make that number, it would do it. If you're dead set on 180, I'm with the other guys. Find the smallest turbo you can lay hands on. Come to think of it that's dead on stock power for a mazdaspeed miata. You could look at a part out from someone who has gone for bigger power and hit your goals.

A real BB 2860rs should spool pretty nicely, i've got one in the garage and will be finding out soon enough.
However, the china ones are pretty laggy, because journal bearing, less efficient, etc. I'd stick with the sr20 t25 for your power goals (that's what I'm currently running). Seems to put down near 200whp at around ~10-12psi.

I have been tempted to give this turbo a try
Nissan Skyline GTR BNR R32/R33/R34 S13 S14 Turbo T28 GT2860 SR20 KA24 SR26 25 20
seems similar to a 2560

The 2860 isn't too big per se, but will be somewhat laggy and is larger than you need for your power goals. However, if your friend is giving it away you can throw it on there and save $$.
Just depends on what your goals are and what your budget is. If you want quick spool and can spend the money, the 2560 is the perfect turbo for a stock-rods 1.8.
