Hi, im sure this has been posted many times so I apolagize but I can not find the info.

I am building a G10. Stock but the cam will be a eco cam from 3Tech.
I remember reading that it is recomended that a 10* cam advance be used.

Any opinions on this would be helpful, thanks

I used the econo cam with the 10 degree gear on my 98 Metro and could not be more satisfied. All depends on how you drive it. If you drive at high RPM's, just get the gear. If you shift at low RPM's and want to save fuel, get both.

I agree with John, I am happy with my +10 gear and economy cam.

I have an auto as well and I'm about to finish my first tank with an XFI and +4 gear, which is roughly equivalent to and econo cam with a +10 gear. So far it looks like if you do a lot of highway driving you'll want to keep the stock cam. I'm turning 3500+ RPM at 60 MPH and I think the smaller cam puts the sweet spot well below that RPM range. I was running a +10 gear with the stock cam before and it looks like it was better (for MPG) above about 50 MPH for me (2900+ RPM or so).

The smaller cam at +4 FEELS great, lots more low end and drive-ability so I'm going to try it w/o the advance, which will still be +6 because it is an XFI cam, and see if the higher speed MPG picks back up...3 gears just isn't enough with these cars.

If you drive a lot of highway...buy a 5 speed. Fuel savings will pay for the coffee.

Don't worry about an ECO cam, you can't use it at those speeds. :)

You may actually be able to use a performance cam though...
