JHEIII874T5M Posted September 19, 2007 Report Share Posted September 19, 2007 If it's automatic - 15G. If it's a factory equipped manual - 16T.Best single HP maximization mod would be a chip (software remap). I would strongly suggest you invest in silicone hoses and a full stage 0 maintenance check up before you take this step. By stage 0 I mean spark plugs, fuel filter, distributor cap, ignition rotor, plug wires, etc. Link to comment Share on other sites More sharing options...
