I've read that I don't need one 'till I upgrade to bigger injectors. Mine are stock. Will I even benefit by adding a Cozmo pump now or should i wait.


I'm planning on adding an SMIC or a high-flow cat real soon.

nah, you really don't need one. You may need one when you get bigger injectors depending what you are doing. If you have a fuel pressure gauge, just monitor it, if it starts to drop drop off at higher rpms, then you need a new pump. It is a good iddea to raise the stock fuel pressure when enlaging injectors, in which case you will definately need a new pump. The cosmo one is great, it just plops in. Just get ready to enjoy the smell of petrol.

So, don't even worry about it until you get new injectors and increase fuel pressure. Or if you get some huge inhectors liek 1600cc.

If you plan to run 13 or more psi then I would recommend an upgraded pump.

Usually 330 or so rwhp is about when the fuel system is maxed out. There are a lot of people running more than this on stock fuel system and not having problems but a fuel pump is pretty inexpensive insurance. If your fuel pump doesn't flow enough fuel for your mods, you could detonate. With your mods now, you're fine. But if you start adding a few more and running higher boost then just get a Walbro or Nippendenso pump and 1200cc injectors - but that's only if you plan on going over 320-330 rwhp.

Thanks for the helpful advice guys. I guess I just got excited when I saw a Cosmo FP cheap on the parts trader...
