It's a brake system that gets rid of the booster I place of a hydraulically actuated pump that is fed from the the power steering pump. Mostly used on low to no vacuum braking situations. ------------------ 86 SE Convertible 3800sc 4t65e HD(2002), Gen V, 3.5 pulley, SD headers

but do you want to hook up a power steering pump, run lines up to the front, add weight to the car, add problems that are costly to fix, just for the same braking power?

That in a nut she'll is what I'm wondering, if all that's worth what ever gains in braking. There's more to it than I initially thought, seems to me the answer is no.

And lots of GM turbo applications and especially the turbo diesel engines like the Duramax.
I see no upside in using hydroboost unless you have a boosted or low vacuum engine and can't get enough vacuum to run the brakes. Otherwise it's a fix for a problem that doesn't exist.

One advantage to the hydroboost is the ability to have consistent multiple brake applications while still under throttle (if your an autocrossing left foot braker).

Many cars w/o turbo etc uses this. hydro booster is small and designers can use boost pressure as part of ABS system, auto braking, etc. Some new cars does, or will use in near future, electronic brake boost for above reasons and more.
Converting Fiero vacuum boost to use either? Even if you can, likely a bad plan. Anything goes wrong could cause big problem. If brake boost fails many won't be able to stop in even 2x normal stopping distance.
Note that Vac boost can fail w/o being totally dead. Common issues are Leaking or block vacuum line/filter, one of two diaphragms is dead, control valve problem, vac check valve bad or full of crap.
