oh ok. I was told that was the us market over here they were a single carb version I was looking into cams for the d15b4 and obviously there is none but there is heaps for the b2 so this is why im asking as if there is no diff beside the carb then cams would be a option
In theory you can fit any d series sohc 16v cam to your d15b4 so long as it has a fuel pump lobe on the cam.
You can fit a efi d series cam aswell, but then you will need a electric fuel pump and block off the old mech fuel pump hole on the head.
Also grab a adjustable cam gear to be able to dial in your new cam.
Im not too sure seen a few posts people saying use cams for the SOHC zc but I want something that's going to go well with some new carbs looking at quad r1 40mm carbs
Sounds cool. Im guessing that people recommend sohc zc cams as they are cheap and the most aggressive factory sohc cam profile. You can still go aftermarket like a bisimoto cam or get your own cam reground here from a place like clive cams etc.
D15 with quads will be awesome.
