- When swapping a B16 into a CRX chassis a common modification to get the alternator to clear the engine bay is to dent the inside of the engine bay to allow for clearance.
This video shows how to swap a D-series alternator pulley onto the B-series alternator so there's enough room to clear the engine bay without having to hammer a dent in the frame.
Yes sir! I'm glad you put this video out. This helps tremendously, going thru forums and actually seen it is night and day. The only thing is the B series alternator I have for some reason doesn't line up with the top bracket.
Glad it helped!
@@MakeItSo after a long while I now just finished doing this same pulley swap. I got my hands on an obd1 alternator and mounted perfectly, the OBD2 alternator did not line up at the top bolt. Have you had any issues around this pulley swap?
@@marcozuniga8163 So far no issues whatsoever. I'm using OBD0 alternator.
Whats up, I'm getting ready to finally turn my car after 3 yrs of building it. Im trying to locate what alternator belt to run. Did you use the stock Ef? Thanks
Nevermind I saw someone asked already. Thanks
Man I wish I knew this before I did my swap and hammered in my frame rail!
I found this pulley swap described in an old forum post somewhere and decided to give it a shot and it worked out.
Only thing that might keep me from doing this is that the belt might have the potential to walk over to the empty rib on the crank pulley
That's a good point. Might hasn't walked yet. Been about 100mi so far.
If it were to happen, I would expect it might take awhile, once the belt has stretched/lost some tension. Do keep us updated!
The question that i have is, the SIR jdm version came with a b16, what alternator it use?
I don't know the model number. But it had large enough pulley that you need to dent the USDM chassis for it to fit. Maybe the JDM SiR has the chassis clearance from the factory?
What belt did you use. i just has my pulley done like you did
Bando 3PK760
Been running thIs for 500+ miles with zero issues.
@@MakeItSothanks for the info, I bought 3PK760 but I also found 3PK750 which is about .5in shorter, this allowed me to have the alternator pushed all the way forward and kept the clearance from the pulley to frame about .5in as well.
@@marcozuniga8163 Nice! I'll check that out when I have to replace mine.
Did this prevent you from having to hammer the frame?
Yes. It fully clears the frame with no denting required. I'm behind posting videos but eventually I'll post one showing the clearance.
@@MakeItSo great! I have a b20v that I want to swap into my 91 wagon and I didnt want to beat the frame in if I could avoid it. 👍👍
Have you had any problems since installing it like charging issues or anything?
I thought the same thing. Smaller pulley slower charging, but I haven't had any issues so far. Seems nominal.
@@MakeItSo I greatly appreciate the feedback I've been looking into doing this for a couple months but no one has said anything about how it worked out or if it caused problems
@@MakeItSo smaller pulley make more current than the bigger pulley because if bigger pulley completes 1 rotation than smaller pulley rotate 1.5 rotation people changing their bigger pulleys to smaller pulleys to get more current from alternator
