I'm just after sum simple mods under 2k each which will make a good power increase and by how much kilowatts roughly...
e.g exhaust w/extractors... ? kw
cold air intake ... ? kw
plz help, thanx
Don't waste your money on an Ecotec... you won't get much out of it unless you supercharge it.
They aren't the best engines out there... if you really want you can do extractors, exhaust and cold air but i can't see there being any huge advantage from it.
If its pretty stock now, pull some suspension height out of it for sure.
