There are no "automatic" or "manual" transaxle specific turbos. There are cases where the type of transaxle comes into play - example, tuning of the system or wiring in of an EMS system. But the turbo itself and physcial hardware doesn't care one way or another.
Depending on the power levels you expect to reach - significant mods to the transaxle may be needed. Manual transaxles can get a upgraded clutch/flywheel/pressure plate - to cope with added heat and have enough clamping force to effectively get that new power to the wheels. For automatic transaxles - first thing is controlling fluid temps - that means running quality synthetic fluid and a properly sized auxiliary cooler. If power levels are much beyond 175-200HP - looking at rebuilding the transaxle. New valvebody, upgraded clutch packs/bands, revised stall speed / heavier duty torque converter, etc. Level Ten is one vendor that caters to automatic transaxles - but will not be cheap. We are talking thousands of dollars here.
From what people have experienced - running 170-175HP on a 4-speed auto with auxiliary cooling seems to do the trick. All depends on how you drive and how maintenance is carried out. If you plan on pushing more than that - I'd suggest a long hard look at what you are getting into. Could be a very expensive proposition for the amount of power gain you would get.
Good example - coworker had a bone stock 2001 Prism, 4-speed auto, great shape, 75K miles. Had the horsepower bug, so was looking at boost to solve that. Sounds like a good idea until you start adding things up. Especially if you opt to do it right and not half-a$$ it, as this case, it was his only vehicle. Factor in the costs associated with the turbo and associated hardware, brake upgrades, suspension upgrade, cooling system upgrades, tune for EMS, revised exhaust, transaxle upgrades, gauges, new oil pan, tire and wheel upgrade, etc. Even doing a significant portion of the install himself and shopping around for good prices - he was looking at almost $10K in modifications, parts and labor. Talked him out of it - later he found a good deal on a 2005 Evo - traded his car in ($4135) + $10K he was going to spend to make his Prism a little bit faster, ended up with the Evo in his hands - a car with superior aftermarket support, all the engineering to support those mods, and he has a better platform to build on down the road. He was all grins after that.
Not saying that spending all that money to have turbo project is a bad thing - the experience that you could gain would be invaluable. Hell, I was in that same position 20 years ago with Hondas - back then you had to fabricate EVERYTHING youself - very little aftermarket support here for imports. Now that I look back on it, I'd have to say that experience was a pretty expensive lesson.
