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.

    • Hope you aren't too sore after that one, might take a day or 2 to notice yet and I guess it is a loooooong drive home. On the bright side, tube frame front end is a thing at superlap, right?

    • The chart of front pressure to rear pressure (with one being on the x axis and the other being on the y axis) is not a straight line on a typical proportioning valve. At lower pressures there is a straight line with one slope, and at higher pressures that changes to a lower slope. That creates a bend in the line at that pressure, called the knee point. If you do not change the proportionng as the pressure gets higher, you will suffer excessive pressure (at one end of the car or the other, depending on which way you look at the proportioning action) and then get lockups at that end. The HFM BM57, from my memory of previous discussions, is based on the BM57 from a different car (to a Skyline), with a different requirement for the location of the knee point and the distribution of pressure front to rear, and so is not a good choice for an upgrade on a Skyline. Here's a couple of links to some old posts, one from here, one from elsewhere. A lot of it pertains to adjustable prop valves, but the idea is the same. There are plenty of discussions on here about this issue from al the many years of people wanting a cheap/accessible option. https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/ https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/  
    • Yeah dunno why johhny posted that here with no context, just post on FB/insta bro where he put it up?  Laine had an off at T4 during Thurs prac, he's ok, car is less than perfect, they are done for the weekend, he can fill in the rest. Bando also binned it like 100m up the road.   
    • I feel there must have been a FB/insta post and the weekend did not start well at all I hope everyone is all okay
