this is in my 89 crx si. right now i have a b20 bottom end. what alternator do i use? can i use my d series one? or do i have to use a b series one? i really dont wanna rewire for the alternator but if worse comes to worse ill do it. any suggestions. one last thing what bracket do i use?

 

not sure on the bracket, but a d series al;ternator would work and you shouldnt have to reiwre either way the connector and positive lead should be the same regardless

 

so your saying a d series alternator will bolt onto a b series bracket?

 

No, the d-series alternator will not bolt up to the b-series brackets. I've tried with my b16 already. They almost fit. I would just use a 90-93 Integra alternator and you won't have to worry about changing the wiring.
