brake booster question

[r3v_v3ng3]

anybody have a feedback on how your braking system felt, when you changed your brake booster for a smaller one to accommodate the turbo?

the reason being is that my car has abs and a full z32 brakes and master cylinder. i have the ebay t3 topmount manifold and its hitting the master cylinder about an inch. if i put the s14 manual booster it will give me enough clearance for the turbo. so just wondering if anybody have experience on running a non abs/auto booster with a bigger brake setup.

It will be compromised if swapped for a smaller unit. The best bet is to get a different manifold. I suggest the JGS...

The top mount SSAC EBay mani is NOT a quality manifold. It's also prone to boost creep.

Get a good manifold

Never compromise braking for more power.

If you comprise braking for power, how will you stop?

[r3v_v3ng3]

yeah i figured it will compromised it but didn't know if its the braking distance or pedal effort.

well since i'm low on funds, i ended up cutting the flange and got a 1/8 inch steel from OSH and use it as a spacer so the turbo is somewhat sitting straight, not angle as before. Now it has the clearance that i need.

just hope my welds hold up

Nah... hope the metal used for the manifold holds the weld... 50 gauge steel tubing isn't that strong lol (note the exaggeration)

probably your pedal effort will increase. But most important I think is when you run a turbo, the system comes under pressure instead of vacuum.. there is a check valve in the line running from manifold to the booster so it doesn't lose vacuum under boost. make sure thats still installed. no vacuum means no assist. Try to find a booster that perhaps is not as thick but larger diameter so you keep same overall volume of the canister. Then you shouldn't see much degradation or negative impact on your brake function.

best of luck,Dave
