With those mods? No, you don't need a fuel pressure regulator. An FPR is designed for a normally-aspirated build-up or some kind of forced induction since it increases fuel flow to meet the extra fuel demands.

Getting an intake/header/exhaust will actually have you running rich and you want to do the opposite of the purpose of an FPR and lean out your fuel mixture with a V-AFC or similar device. I've heard that an FPR might help out with optimizing the atomization of the fuel combustion but it's really just speculation and not dyno proven as far as I've ever seen. An FPR would only be beneficial under your circumstances if your stock fuel delivery were defective and if that were the case, you've got bigger problems, my friend

Yeah, that's tru, and on top of that, if you ever plan to get a VAFC or Hondata or something along those lines, unless you're really running big injectors, you probably won't even need it with a lot of mods.....

Later,

Agree, don't waste your money on an FPR, you just don't need any more fuel at this point.

What rims are you buying?

Well, the OZ F1 are heavy as hell, be aware of the fact that they'll probably slow you down.....

But when I look at my friend's rims I'm lucky!! He has 18" on his ITR :shock: 16" is a good choice if u want performance AND style. Which are the lightest rims (16"), o.z. superleggera is one I think?!

Well, that's the lightest oZ rim any way, there are tons that are lighter, for example, I run 17" by 7.5" width in the racing hart cp035, and they only weigh 12.5 lbs....

Just a matter of doing your homework, you don't even need to spend a lot.

Good lord Aj! You spent more money on your rims than I have on all the mods on my ITR combined! :lol:
