like it says i have a civic si and i am dropping in a gsr swap and using all civic si mounts including the ac bracket ... now my question is do i use a gsr compressor or a civic si compressor ... or are they the same .... i have searched for this but couldnt find anything ...

 

i know this is stupid, but the em1 is the 99-00 si? i cant remember all these chassis codes, but if it is, use the ac brackes and the compressor out of the em1. if you dont have ac at all, to use the gsr compressor you will need a gsr bracket. if i remember. PLEASE CORRECT ME IF I AM WRONG.

 

your wrong ... you need the civic si bracket or the del sol vtec bracket .... i have a 2000 si with all the stock a/c lines but no compressor .... i am installing a gsr motor so what compressor will i need ... the si compressor or the gsr compressor ... are they the same ? i already have a gsr compressor but if i just need to make sure the ac lines will bolt up to it without any problems

 

use a civic si compressor i think the lines will be different

 

I have a compressor if ya need one. It came off a 2000 civic si. I dont need it, its just laying around. You can have it if you pay for shipping.
