I just finished up a hydroboost conversion last night. It is incredible. I held 15 psi on the footbrake with no effort. I bought the car with a failing PM so I cannot compare to a properly working PM. I converted to vacuum and it was ok. I rebuilt the motor with a 215/220 cam and I was only pulling 10-12" of vacuum. I could build 0 boost on the line. The HB conversion was pretty simple. The only fabrication was to the firewall bracket. I used the PM bracket as it has the correct angle to keep the unit from hitting the hood. I will post the details with part numbers and the fab needed, etc.
The unit came from a 1995 Chevy Astro van. I paid $46 for the HB/Master cylinder and $190 for all the fittings/lines, etc. There are companies that sell a ready to bolt on kit for between $650-$800. I am on a budget.
