Ok guys there is a lot of mis info on both of these parts. I need clarification. I have a blown gsr longblock that I am transferring parts from to my new jdm b20b platform. However I have ran into two problems. I realize that the b20 crank pulley is larger than the gsr pulley. I dont mind to run either one just as long as I keep a/c and power steering.

Do I use the jdm b20b a/c bracket or do I use the gsr a/c bracket? Should I use the a/c compresser that has 30k on it that came with the b20 or the gsr compressor with 225k? What about belts if I use the b20 pulley? Will the b20 a/c bracket allow me to use the torque mount in an integra?

Onto the power steering, the upper gsr mount will not bolt onto the b20 block, but the lower bracket will. Do I need an ls upper mount and run the gsr pump? Or can I just run the b20 pump and bracket and keep the gsr crank pulley and find the right size belt?

Sorry for the questions im just so tired of misinfo and half *** answers!! Help me if you can but if you dont know, then please dont post more misinfo.

 

Use the B20b brackets and pump, if the A/C compressor manifolds are the same, [A/C hose assembly fits] use the B20b compressor, if the manifolds are not the same you will have to change the hose assembly to the one that was on the B20b compressor, [it must fit at both ends or mods are needed] or use the GS-R compressor, if it can be mounted properly.

What's wrong with the B20b crank pulley?
If nothing, use it, if it needs to be changed, use the GS-R pulley and get the belt that fits. 94

 

the b20 crank pulley is larger in diameter than the ls or gsr crank pulleys. most people change them or use the b20 pulley for SC applications

 

The b20 a/c compressor and bracket won't work for integras. B20's have compressors like civics so u have to use your old compressor and bracket.
As for the power steering pump....u need to use the b20 or ls pumps because the pump mounts to the head of the engine and vtec heads are different from non vtec

 

why wont the b20 a/c compressor work on the gsr bracket? the bolts seem to line up and the a/c lines seem to be identical

If the GS-R compressor mounts so clutch assembly pully is lined up, and the hose assembly, [GS-R hose assembly] "reaches" around the B20, your good to go. 94
