I have searched but have not found any concrete information on this topic.

I want to know if the 88-91 Prelude Booster and MC is a direct swap to the 88-91 CRX. Thanks in advance for the help.

 

I'm not sure but the front Hubs annd Brakes are

 

the booster will fit and the master cylinder will fit. the only thing you need to do is bend the brake lines just a little bit to get them to line up with the master cylinder. i have both of these on my 89 civic.

 

Thanks for the responses.

 

i would just go with 1991 civic ex MC, it fits without bending ur hard lines, and the booster also fits.

 

is there a difference between a 91 civic ex mc compared to the 2.0 si prelude mc?? well, except for bending one of the lines to make the prelude one fit

 

ive wanted the know the same question

 

are they both 15/16 mc for the civic and prelude mc

 

i think they are both 15/16 MC. i just used the prelude ones cause i had the car sitting around for parts. i didn't have to buy anything.

 

prelude fits and is easier to find (at least around here) paid $10 at the junkyard

 

is one better than the other tho? which one would be better for a brake upgrade?

 

or is there no difference between the two mc for the prelude and civic

is the prelude when better because it has a heavier body than the civic's

 

i think they are both 15/16 i only got the prelude one since it was much easier to find

 

thanks man...jus seeing if there was a performance difference...but i guess if its both 15/16 it doesn't matter

 

not to thread jack but is the da 15/16

The EX master cylinder bolts right up to any other CRX and Civic booster, so you do not need to change that unless if you have too. Correct, you also do NOT have to bend the lines in anyway.

Yes, although they are both 15/16'', the mounting locations is different on the prelude MC (where it bolts up to the booster). You will need to use a prelude booster if you use the prelude MC, and can use the stock booster if you use the EX one.

No. I wouldn't mess with the booster, I'd put an EX one on.

the da integra is 15/16, and to put that MC in, it will pretty much be the same as the prelude si mc/booster. Just put in the da booster and MC and you will need to massage the brake lines a little and thats it.

 

^^^thanks for all the answers Mach69 that helped a lot

 

i got a MC from a 1991 civic EX sedan. i should probably put that on. its been sitting in my garage for ever.
