Has anyone jetted, jet, jetting their 4 barrel carb? I spent some time in NZ a few years back and spoke to a Mazda guy who told me to save the money on a bigger carb and just jet it out and get extractors or headers, to get fuel in and air out better and the stock motor will run a lot better.
Has anyone done this? I have put the extractors on and a straight pipe which sounds better but the number on the jet without a lot of trial and error would be a big help.
Anything related to fuel delivery, induction, turbos, emission control & exhausts
