Sorry i know this may be a dumb question for most. but i search and i didnt find anything specific. Maybe this as a good reason i guess but still want to know.

So does it fit EG? any diy?

 

Why?

 

why "why" does matter? it is to fit my brake caliper upgrade, i dont find any good dc2 booster/mc atm and a new shape S2000 b/mc sounds good if it fits as good as dc2.

 

You ask a question. I ask a question. It's called clarification. If you don't help us to help you then don't bother posting.
Since there is nothing on the S2000 booster I'm going to say no. You can use the Master Cylinder all day long.

 

you right i just dont understand it very well. But anyways ill wait for more info or a dc2 b/mc.
My actual situation is EG4 with oem booster/mc, dc2 Fcalipers, mgzr Rcalipers. Of course my b/mc is not good for this calipers i already knew it but i just let it for a while. Now i want change it but dont find much available near@good conditions, found a s2000 one and put me thinking

 

Closest thing I could find.

Swapping the booster out will do nothing unless your booster is bad, one will not work any better than another. The master cylinder however is a different story.

 

On a portuguese forum people told me it is possible to do it and its quite comon to do it on CRX. Im Waiting for more info. if i fit it i will try to take pics

 

Yes, it fits!!!
I swapped S2000 bb/mc into my delSol.
You only have to use a braided line (with right connection and banjo) because of the different angle between mc and car's front hard line
