i have a stock 99 si b16a2. i can pick up some gsr cams for $30 from a buddy. is there a differance in 99 si b16a2 cams vs 99 gsr's? i found there a dif in old b16a and gsr but the question is differance in 99 si b16a2 cams vs 99 gsr's.


oh yea its going to be turbo'd with a ramhorn mani on a 60-1 stg 3 wheel on 14psi

 

We had both b16a2 and b18c1 cams in the shop which we measured and couldn't notice any differences. Not worth wasting your money or the time to install. We swapped the gsr's in anyways because the head was already apart and didn't notice any differences. Also the a/f measured by the wideband while datalogging didn't change at all before or after the swap.

 

keep the stock b16a2 exhaust cam,,,but use the 99 b18c intake cam..

the b16a2 exhaust cam has more lift then the 99 b18c exhaust cam,,,but the 99 b18c intake cam has more lift then the b16a2....

 

so the 99 usdm si b16a2 cams are dif between gsr..they are not the same?

 

Gsr cams if the're $50 or less.

I would go with the gsr cams for boost.
