K20A3 cams vs K24A4 cams
I have a K24 accord, I am looking at possibly putting K20A3 cams in my motor. According to the shop manuals, both motors have the same lobe heights on all the lobes. They still have different part numbers though. CRV and Accord share the same part number for cams.
I'm told having the same lobe height doesn't necessarily mean both cams have the same profile, lobe height affects lift but not duration. But even in that case, does it pretty much mean that there won't be a big power difference between the two cams? Please help.

You're probably not going to breathe very well, especially in high rpm's as the k20a3 cams are meant for a 2 litre, not a 2.4 litre. Your best bet is probably tsx cams, as it also has a k24. You'll probably get a good amount of gains from those.

The TSX cams won't fit the accord, the TSX has all 3 lobes on the cams and true vtec.
The SI cams supposedly have fatter lobes than the accord cams. Apparently the lift is the same on all lobes, but the duration is longer on the SI cams. I'm just wondering if anyone knows how much benefit there is to this swap.
