Hey im looking at doing some upgrading of performance parts on my car and one of the most obvious upgrade is a higher flow fuel pump...

Was wondering if the OEM R33 GTR fuel pump would be a good upgrade for my R33 GTST? What are they rated at compared to say a 044 or something?

I was talking to my mate about it and he was saying i would need to upgrade my fuel pressure regulator as well other wise it would be a useless upgrade of the pump. Is this true or is this just drunk mates thinking they know best? <_<

I have a gtr33 pump in my car and its a direct swap and easy to install (takes about 2 hours by yourself) without hacking / cutting wiring etc.

It flows good for around 300rwkw however your injectors will max out before that stage anyway. Once you need more fuel, ie: larger injectors you can simply go for a nismo fuel reg and crank up the rail pressure as needed.

The stock rail and injectors with a gtr33 pump should be fine for just under 230rwkw ish. I'm seeing 80% inj duty max on 193rwkw with gtr33 pump

cool thanks for that mate..

yer well as said in another post im wanting 200-220rwkw on the stock turbo so yers sound like the GTR pump is the way to go.....

Do you remember how much it was roughly?

    • It is an absolute lottery. They can and have died at stock boost with low usage at all. The turbos are now anywhere up to 36 years old!
    • Huh, wonder why it blew then. I never really beat on the car THAT hard lol I dailyed it and the turbo blew after 6 months
    • That's odd, it works fine here. Try loading it on a different device or browser? It's Jack Phillips JDM, a Skyline wrecker in Victoria. Not the cheapest, but I have found them helpful to find obscure parts in AU. https://jpjdm.com/shop/index.php
    • Yeah. I second all of the above. The only way to see that sort of voltage is if something is generating it as a side effect of being f**ked up. The other thing you could do would be to put a load onto that 30V terminal, something like a brakelamp globe. See if it pulls the voltage away comepletely or if some or all of it stays there while loaded. Will give you something of an idea about how much danger it could cause.
    • I would say, you've got one hell of an underlying issue there. You're saying, coils were fully unplugged, and the fuse to that circuit was unplugged, and you measured 30v? Either something is giving you some WILD EMI, and that's an induced voltage, OR something is managing to backfeed, AND that something has problems. It could be something like the ECU if it takes power from there, and also gets power from another source IF there's an internal issue in the ECU. The way to check would be pull that fuse, unplug the coils, and then probe the ECU pins. However it could be something else doing it. Additionally, if it is something wired in, and that something is pulsing, IE a PWM circuit and it's an inductive load and doesnt have proper flyback protection, that would also do it. A possibility would be if you have something like a PWM fuel pump, it might be giving flyback voltages (dangerous to stuff!). I'd put the circuit back into its "broken" state, confirm the weird voltage is back, and then one by one unplug devices until that voltage disappears. That's a quick way to find an associated device. Otherwise I'd need to look at the wiring diagrams, and then understand any electrical mods done.   But you really should not be seeing the above issue, and really, it's indicating something is failing, and possibly why the fuse blew to begin with.
