would there be a big difference in gas mileage from a 3100 vs a 3400? im planning on putting a 3400 into my sunfire and just checking to see if there would be large enough gain in gas mileage to go with a 3.1 over a 3.4. thanks.
no its not there both basicly the same

Well, if you get the 3100 you should only get one that's 2000 or newer, ortherwise it's pretty much a waste.
My 3400 got me 23mpg wtih a not real professional tune on mixed city/highway driving stuff, heavily abused with WOT pulls from stop signs and red lights.
I was gonna see what it got when driving it nicely, but my starter went out. So I ripped out the whole engine harness to change it. Car's been down for a while.
i find it amusing that SHOoff has nothing better to do but follow me around & be an unhelpful dick in even cross-forum. - Jon Mick
okay..yeah im gonna see if i can find a 00+ 3400 then.

i had a cutlass supreme with the 3100 in it and i was happy with the gas mileage in it so
This question just doesn't make sense. If you are concerned about saving a little money by using the more fuel effecient engine, why not just save ALOT of money and not swap to a v6?
A 2.2 5spd is rated at 33mpg highway. Don't expect to get that with the v6

well ive been seeing everyone on here getting in the 20's with the v6's so.
No lie when I first put my 3400 in I got 45mpg on one trip...
