S13 Brake booster w/ABS same as S14??

[Chrischeezer]

hello,
so last night i discovered my Master cylinder has been leaking into my booster. there was about half a quart of fluid in the booster.. i was wondering where all my brake fluid was going for the past week. *yay

I just got another ABS master cylinder because i was told its the same size as a 300ZX MC. but now i need a ABS booster (cant trust a booster that was filled with brake fluid right?), and the s14 boosters look very much the same. are they?

-i have been using castrol GT LMA fluid, it seems to have the highest boiling point of anything on the shelf, any recommendations?
-i have ECR-33 brakes all around with stainless lines.

s14 auto has a dual diaphragm design while the manual has a single. They are all pretty much interchangeable. You may have to move the lines around since the lines are run differently on the s13 and s14.

Abs uses 2 lines while non-abs uses 3.
