best thing you could possibly do is buy hp tuners.

throttle body spacer is doing you absolutely zero. take it off and save it for an alcohol injection nozzle for someday if you ever go boost.

dont bother doing the 2.3 tb, OEM is going to be offering boring and polishing of your stock one soon, if you can wait til then hit up smgmotoring.com. they do the same thing.

you wont need to upgrade your fuel system for more flow unless you go boost or nitrous. however... having an adjustable fuel pressure regulator would be a nice tool to have, even with hpt.



I'm tired of wasting my time... now I'm breakin' free.

this, and get a new cat. there's no reason to remove it on a stock car, all you do by doing so is make your exhaust sound terrible.
