Im in the process of top swapping my grand prix and i want to be able to mod without the worry of knock. Ive thought about running meth and intercooler combo to run a smaller pulley but many have said id only probable be able to run a 3.4 pulley. So im wondering if i use e85 and other basic mods ex.headers 180*,colder plugs and wires could i run a 3.0 or maybe even smaller? Ive seen e85 flex fuel conversion kits where i guess you can switch between gas types. If i got this could i run the smaller pulley and not change anything else except injectors? Or could i get a tune and 60s injectors and be ok? thanks for any info.
