Modern cars that utilize hydroboost have the entire brake and hydraulic system designed around it.
Generally they utilize a type II steering pump which typically has higher flow at lower pressures than the typical P-Series saginaw pumps found in most muscle cars. Additionally, the caliper sizes are designed along side the hydroboost to counter-act some of the pressure's it builds and helps to create a better pedal feel while adding modulation.
If you're re-engineering the entire brakes system (The OP might be), you can build it just like a newer factory car and probably get very similar results.
Retrofitting it directly into something that's already there usually creates a pedal that is very on or off. Some people do like that, I will concede. But lightly touching the brake pedal and flying through the windshield doesn't mean the car has great braking performance. It just means it piles all of it's available pressure to the calipers all at once.
There's a reason most of these units come on big trucks and vans. With exception of the SN95 mustangs, almost no performance cars come with hydroboost setups. The only reason they were on the SN95 cars is due to space limitations created by the large modular motors.
