i was wondering how well these engines respond to the basic bolt on mods, header, intake, and maybe a cam etc... from what ive learned about the ford 2.3 they dont respond too well to mods like a new cam shaft unless its the maf engine i believe.. im just curious to how well these engines respond to new parts and if they are worth the money...i know turbo is really the only noticable huge gain, but thats a little outta the pic for the time being..i need to get the car first for one
