You should be able to do it for less than $1k if you have fabrication skills for your exhaust manifold. The MK3 supra ct26 was the initial plan for mine, but I didn't like how low it had to be in the engine bay where I wanted it, so I am going with an IHI hybrid that a friend found locally. It will fit where the A/C compressor would normally be(once you remove the bracket), but I didn't want it there.
That turbo will be capable of more boost than a stock m42/m44 can take, so tread lightly. They're very good turbo's though, and capable of more than the t3/4 "Kit" turbos available. Just remember, it should be coolant and oil cooled.
My recommendation, find where you want it to sit, get some flanges, and tack weld up a manifold. Then have it tig welded. It never hurts to go bigger than you need, especially if you ever do a low comp engine down the road.
