My buddy picked up a used sir bb and m/c for his gsr swap on his 99 EL.

The m/c size is exactly the same as what he has now on his EL, 15/16. So is this true Si and SIR are the same?

Since hes doing a gsr does it matter if he uses the Si/SIR or should he find a gsr.

well 96+ si - 2 discs - 2 drums with abs

sir -4 wheel discs with abs

gsr - 4 wheel discs with abs

el - 2 discs - 2 drums with abs

now this gsr swap is motor swap or suspension/brake swap?

they are probably the same , all of them , its just the proportioning valves are different,
cause some cars have 4 wheel discs +abs

and some have drum rears

just a brake swap

Hi Matt,
yes, si and sir share the same MC and BB. but NOT the GSR. 99-01 GSR uses the same MC and BB with 99-01 ITR. I'm using my stock MC/BB (15/16") with GSR front calipers. Nothing wrong so far. But i'm sure if u go for 1" MC/BB, u'll hv better pedal feeling. hope it helps.

Did you just swap out the front calipers from the GSR onto your existing brackets or did you have to swap the whole thing?

i just swap out the front calipers. it bolted up fine, not even offset problem. but mine is SI.

yeah, all non-VTEC 6th gens have 13/16, and all VTEC 6th gen got 15/16, even the SIR. I use it to power 4 piston calipers, and the 15/16 MC is totally up to the task!!

Si and EL share all front susp and brake parts

Not TRUE..... coz my 98 Si have 13/16 and my friend's 99 SiR have 13/16
