Hey guys
I just got this idea and i want to share it, and allso get some suggestion if it will work. Iw ant to try swap camshaft from AB to AC GSR. Cos the AB one ist little sharper then AC one, so if it was made then i want to know how it works and what is plus and minus, or if it was not made, than any suggestion what can hapend, becouse mi opinion is of little increase of HP or am i wrong, thanks for imput.
I am just afraid, if i swap it what will hapend with the valwes becouse the amount of mixture will be lean copare to AB, and on ac you cant adjust mixture becouse of O2 sensor is doing it him self, but thanks esky, but do you thing it is worth to try, and if i remove all cat.convertor it maight have little biger improovment for power output right?
the cam specs that i have are
AA AB 21/63 63/21, 264 deg, 42 deg overlap, 111 deg lobe centre
AC 19/57 57/19, 256 deg, 38 deg overlap, 109 deg lobe centre
The ecu can fuel air mixture so i dont see a problem, the AB cam is not a huge race cam.
It's easy to change so give it a try , if you don't like it you can swap it back.
removing the cat converter would also help.........but is illegal.... in Australia anyway.
In Czech it is allso illegal, but i had inside an AB and that one is non kat, and we can get erased engine number out of papers so i catake them out from AC and nobudy will ever find out, but with that cam shaft i will try it, and i give a post how it went and fealings from driving, thanks for tips 
Yes i swapped my AC for AB cam but also swapped turbo , injectors and ecu at the same time
so cant tell you if just doing cam will make a big difference, having said that tha AB cam will improve
horse power but it will only be by a small amount................but it all counts..
