Hi,

About to finally put my 2835 pro s turbo kit on my r33.

I thought the 255lph walbro pump I have now might be at its limits? So looking for the next easiest fuel pump upgrade for it?

Looking at the following options:

Bosch 040 clamped to the original cradle

Bosch 044 mounted in tank with a male screw in fitting and modified sock - post-15190-0-85766800-1382582511_thumb.jpg

Walbro 460 lph pump - http://www.skylinesaustralia.com/forums/topic/410989-all-new-walbro-460lph-e85-in-tank-fuel-pump-strainer-kit/

We all know working on r33 pumps is a massive PITA, so I dont wana over complicate things, just pull the current setup out, rig up something easy and drop it back in.

Thanks in advance,

Matty

Best/Easiest is a Nismo/Tomei/HKS pump (all the same pump, Tomei is usually the cheapest)

But this is pricier then a new Walbro. You were asking for the Best/Easiest though so thought price might not have been such an issue

Do that, and maybe do the direct feed re-wire if you want to make sure its getting full power all the time

255 should be fine, but as i found out years ago... Sometimes they are not, even a few months old, if you are running a bit of boost as the Walbro simply don't perform when higher rail pressures are asked of them where the Bosch/Nismo etc kick goals.

So either take the try and see approach OR - Do what 89CAL said, right on the money as always.

my tomei pump didn't like it at all when I put 6 bar fuel pressure through it...

87psi......

Why that much? :S

My Tomei pump has been perfect for the last 4-5 years. Isnt loud, does the job, and has never played up. Great pump :)

Nothing against any others, I havent used them so I wont comment for or against. But the Tomei pump comes with everything, in a cradle, ready to slide in.

wasn't intentional......but it made a lot of ugly noises when it did...

Get the bigger Walbro or equivalent Deatschwerks or if you want Japanese I think the Denso is the same pump as Nismo/Tomei/HKS but cheaper. Anything but a Bosch 044 - I've got one in a steel case insulated inside and outside and its still far too noisy!

For $200 you really can't go past the e85 Walbro. They are nearly silent when installed correctly and flow massive amounts of fuel. The petrol version is only $150 or so, but why limit yourself to dino fuel...

Thanks for all the info,

r31 nismo has me a little paranoid about my current pump now, plus it was second hand when I put it in.

I'm going to go with the 460lph walbro, looks like an easy swap over and reasonably priced.

    • Yeah, it's getting like that, my daughter is coming over on Thursday to help me remove the bonnet so I can install the Carbuilders underbonnet stuff,  I might get her to give me a hand and remove the hardtop, maybe, because on really hot days the detachable hardtop helps the aircon keep the interior cool, the heat just punches straight through to rag top I also don't have enough hair for the "wind in the hair" experience, so there is that....LOL
    • Could be falling edge/rising edge is set wrong. Are you getting sync errors?
    • On BMWs what I do because I'm more confident that I can't instantly crush the pinch welds and do thousands of USD in chassis damage is use a set of rubber jacking pads designed to protect the chassis/plastic adapter and raise a corner of the car, place the aforementioned 2x12 inch wooden planks under a tire, drop the car, then this normally gives me enough clearance to get to the front central jack point. If you don't need it to be a ramp it only needs to be 1-1.5 feet long. On my R33 I do not trust the pinch welds to tolerate any of this so I drive up on the ramps. Before then when I had to get a new floor jack that no longer cleared the front lip I removed it to get enough clearance to put the jack under it. Once you're on the ramps once you simply never let the car down to the ground. It lives on the ramps or on jack stands.
    • Nah. You need 2x taps for anything that you cannot pass the tap all the way through. And even then, there's a point in response to the above which I will come back to. The 2x taps are 1x tapered for starting, and 1x plug tap for working to the bottom of blind holes. That block's port is effectively a blind hole from the perspective of the tap. The tapered tap/tapered thread response. You don't ever leave a female hole tapered. They are supposed to be parallel, hence the wide section of a tapered tap being parallel, the existince of plug taps, etc. The male is tapered so that it will eventually get too fat for the female thread, and yes, there is some risk if the tapped length of the female hole doesn't offer enough threads, that it will not lock up very nicely. But you can always buzz off the extra length on the male thread, and the tape is very good at adding bulk to the joint.
    • Nice....looking forward to that update
