So I got a 90 Integra with a stock b18a1 and I have working ac and working ps, just got a jdm obd1 b16a sir2 and the engine comes with ps and ac..do I use my old ac and ps from my b18a1 or should I use the one that's on the b16 engine? Will everything bolt on?

 

Cant comment on the power steering question, but for your AC compressor to work you'll have to reuse your ac compressor bracket.

 

So I have to take off the compressor and bracket that's in my b16 and put everything from the b18?

 

you have to use the compressor thats in the car, and the bracket from your original engine. that make sense?

 

yea thanks man
