I know for sure that the sirI cams are different from the B16A2 (99-00 si). Now, I'm not aware of being any difference between teh sir1 and the sir2 cams other than the computer.
Although I once heard someone say the sir2 had 170 hp, I woudnt be too sure about it.

 

yeah the cams are diff, the A2's have a bit longer duration and i think they are a bit bigger, i dont know how much more though...

 

The SiRII motor also has a slightly higher c/r. 10.4 vs. 10.2 for the 1st gen. B16A's. From what I understand, B16A cams improved slightly over the years.

 

how much difference woud the sirII cams make in a regular jdm obd0 b16?

I would guess about 4 hp. Some peopole use stock gsr cams too as an upgrade over 1st gen B16 bumpsticks.

The extra 10hp made in the 2nd gen B16 comes from a 60mm TB, better intake manifold, cams, and higher compression.

 

this would be going in my everyday driver................ dosnt make that much diff to me i guess i wont invest it would be like 100$ total to have them in my b16 but for about 4hp its not really worth it in my edd.
