please use search.
If you do not know how to effectively use it please ask.

*Also, next time make your thread title specific, this will make it for people WHO CAN help to post.


back to your question:

No you cannot use 94-01 GSR calipers on your EF si/dx knuckle.
Remember, with your EF si/dx knuckle you cannot use any "calipers off" other honda/acura car which have 10.3' rotor or bigger.

Your options:

a) find (rare) 90-91 civic ex knuckle
it will have 10.3 inch rotor (larger than 9.4 stock si/dx)
it will have larger caliper (piston is 57mm vs 53mm)


b) buy fastbrake.com "adapter"
this will allow you to do 2 things (pick your combo):

1) use calipers from:
EF-EG-EK(ex), DA, DC = all have calipers with larger pad surface and 57mm caliper piston
or
ITR + 90-97 accord wagon + 96 prelude vtec = have even larger pad surface & piston (not sure what size)

2) use 10.3' rotors from:
EF-EG-EK(ex), DA, DC
or
use 11.1' rotors from
ITR, 03 CL, 96 prelude vtec, 88-89 vw corrado
