After installing a z32 ABS brake booster on my non ABS 91 s13 my car has low vacuum reading 12 on my gauge. my car would run like shit and wouldnt accelerate smooth.

i check all my lines and i am positive i install everything back correctly.

whats wrong?

do i need the non ABS z32 booster instead of the ABS z32 booster?

help me out!

Thank You Zilvians!

Where did you get this brake booster? Did you hook up the vacuum line properly?

the brake booster was remanufactured and the vacuum line was installed correctly because before i install the z32 booster it ran well. i am gonna check my timing because i did my timing the same day too. but im sure it might not be it but then again who knows.

Thanks!

I would still put a mighty vac vacuum pump on the booster and see if it holds vacuum. There is a chance that you didnt get a good seal between the master and the booster which would give you a vacuum leak. Really you should always test that after you put a new booster on there.
