are the injecters from a 3.1 bigger than a 2.8?
if so what will i increase besides money at the pump

 

Yes, and on a totally stock car, nothing.

 

What are the simplest mods that will use the increased flow rate to our advantage? And Doward, don't say a turbo, because I know that wasn't simple.

 

Increase the amount of air going into the engine

and at the same time

Increase the amount of air exiting the engine


Normal intake/exhaust won't use injectors to their benefit. You want to use higher poundage injectors then you'd better do some head porting.

 

Now that you say that, it seems obvious. I think I'll wait for those headers before I upgrade my injectors. In the meantime, time to open up the box, and pop on that cat-back.
