Hydroboost brakes....

The powersteering pump should pump plenty of fluid. I've talked to a few guys online who have done this conversion. However, there is really no reason to swap it over to hydroboost, unless you are running a really big camshaft, and the vacuum booster isn't doing it for you anymore, like in my car. I did some research on it, decided it wasn't worth it, and swapped my car over to manual brakes instead. Not sure if that was a good idea either, but that's what I did.

Anyway, you need to get the booster and master cylinder from a 96'-98' Mustang. Then you have to have power steering lines custom made at a hose shop. It's not terribly expensive. I also believe you have to rebend your brake lines from the master cylinder to the proportioning valve, as the hydroboost master cylinder sits farther forward in the engine bay.
