Techy questions on timining and adjustable cam gears

[vinay7777]

--------------------------------------------------------------------------------

All right so out of all the research that i have done here on 3si, i have found for my set up i would want to use adjustable cam gears and take the intake cams +1 degree and the exhaust cam gear -3 degrees.

I know this might be a real odd thing to ask, but why even do and intake cam gear?

Couldn't i just do new adjustable exhaust cam gears and retard that only? Will this work considering i believe the aftermarket gear is wider in size?
My basic set up is:
phantom turbos
660cc
FD fuel pump
aem ems (can anyone recommend someone to help with a good base map??)
street grind cams

Thank you all in advance.

1 deg can make a big difference when it comes to cam timing.
Thats why you get both intake and exhaust.

SO why buy gears..... when you can just get offset keys?

What are offset keys??

I understand the advancement of exhaust cam but if dealing with the 1g cam/crank sensor why are you messing with the intake cam? Certianly those with 2g's or the divorced cam/crank sensor rewire, could utilize the retardation of the intake cam. All you'd end up doing is delaying your ignition timing sequence.

I need to do my own research on this subject.

Cam gears however are cheap. I found a slighty used set from Ebay for almost 70% off new ones. Hell, they appear only to be mounted as a display and were never moved from "0" position.

But yes, what are offset keys? Crank woodruff keys? I'm having trouble imagining offset cam dowel pins.
