i have a crx hf with Si front brakes, 1990 integra ls rears. a 91 civic ex master cylinder

i am replacing my brake booster. should i stick with the stock one or do i need to go bigger?

 

Stock.

 

are you sure? i tried using an ex booster off a civic 1991. but i have a b series swap and i couldnt even fit it in the bay after removing the stocker

 

I wonder why you didn't feel you had to mention that you were having fitment issues in the first post or the last thread you started.

Probably why you aren't getting a lot of responses.

 

I just tried putting on a different booster today.

And if I absolutely have to use a different booster, I would like to know. Even though I would need to remove my intake manifold to get it on. I am just not sure what the difference is between a crx hf booster and other honda boosters, and I dont know how it will affect my brakes. some seem as if they are almost twice the size as mine.

I can get a reman booster. One for a crx SI is a little cheaper than the HF. but I have no idea what the difference is between the 2
