So I need a altenator for my 90 Integra. It has a B18B engine. Just wondering if a alternator off of a B18C1(OBD2) will fit on a B18B. Also it looks like it will be easier to take it off from the bottom correct? Thanks.

 

I believe different obd has different plugs. And yes you take it out the bottom. For an ek we had to remove the driveshaft to get the sucker in...

 

Alternator should be the same OBD but you can always gut them and make them work which I got done to mine.
