Mixing Nissan brake boosters
Long story short, a stud on my P10's brake booster broke and I needed a replacement. Any would do, preferably cheap and now, as it's my daily beater. OEM is very expensive, so first I got an A1-Cardone rebuild. I tested it multiple times with my Mityvac, and it wouldn't hold vacuum! The POS went right back.
I found a guy on eBay selling new-old-stock (i.e. brand-new) OEM Nissan parts with a 1.6L B14 booster for $30, so I jumped. Cheaper than even the sketchy used ones, and most Nissan boosters from the 1990s are pretty much identical outwardly. The seller said it was for a B14 1.6L auto non-ABS. It is a M195T booster like on my SE-R and G20, but drives a lot differently.
It has a long pedal travel like a Buick (ewww), but remains firm once you reach the engagement point. I installed a new master cylinder at the same time and bled everything correctly and to excess, so it should be working right.
I guess the automatic might be set up for that grandma car pedal feel. I don't know if the SR20 pulls more vacuum, too. It's overboosted and has lots of travel with no feel. It firms up if you step on the pedal, release, and stab it quickly again. Maybe a normal vacuum drawdown thing?
Anyway, if for whatever reason you need a new brake booster and don't care about pedal feel, Nissans are pretty much mix and match.
