Default BrakeBooster/Master Cyl Question on Replacement!!!!!

Well, my pedal is weak, and ive tried to bleed it 4 or 5 times now, and still no luck. If im at high vaccum, or i just was on the gas pretty hard (6-8k), and i brake, the pedal is FIRM. but when im just cruzing, its mushy. So i think its my Brake Booster.
I have a 1995 Integra GSR, but i removed the ABS from it, and put on a civic MC/bb. Now, im wondering what can i use to replace my MC/BB? Does it matter if i use a ITR or a non abs civic? Because, i can just buy stainless lines, and route them however i need? Let me know!!!!!!!!!

Functional Test...

1. With the engine stopped depress the brake pedal several times then depress the pedal hard and hold that pressure for 15 seconds... If the pedal sinks there is a problem with the master lines or caliper.
2.Start the engine with the pedal depressed... If the pedal sinks slightley the vacum booster is funtioning properly. If the pedal does not vary the booster or check valve are faulty.

LEAK TEST...

1. Depress the brake peadal with the engine running then stop the engine. If the pedal height does not vary while depressed for 30 seconds the vacuum booster is OK... if the pedal rises the booster is faulty.

CAUTION: Do not try to disassemble the booster
Replace the booster assembly with a new one

2. With the engine stopped depress the brake pedal several times using normal pressure. When the pedal is first depressed, it should be low. on consectutive applications the pedal height shoud gradually rise (pumping up the brakes). If the pedal position does not vary check the booster check valve.

CHECK VALVE TEST:
1. Disconnect the brake booster vacuum hose at the booster.
2. Start the engine and let it idle. There should be vacuum available. If no vacuum is available the check valve is not wroking correctly... replace the check valve and re-test.

The END...

Typed from the helms...

Also I would recomend getting a 90-00 RS non-abs MC and booster... or at least the 15/16ths civic master that bolts to the civic booster... (That is if the booster checks out.)
