Hi all, I hope this isnt a previously discussed topic, did search my best but probably missed it. mods please delete/block if already discussed.

I want to know if anyone has experience with this 'new'? pump from walbro, figures are impressive but is it going to fit and work in my 33 gtst?

I asked in another topic but wasn't really answered.

I have a 255lp/h one running somewhere around the 280-300kw mark with not a worry, but will be heading to about 340-350 ish soon, i dont have a problem with buying a nismo or anything but for the money can one of these exceed?

So, opinions? http://www.racetronix.biz/itemdesc.asp?ic=F90000262&eq=&Tp=

Cheers

I know right, seems ridiculously large flow, but even granted that it most likely wont flow that, should surpass what ill be using it for. Interesting read that thanks.

With those numbers it should support monsterous power... Sounds too good to be true

Ever heard of anyone trying one?

Maybe ill be a guinea pig unless there's a reason why not to give it a red hot go?

**CORRECTION**... Looking @ the graph again on the link, it's @ 14v/70psi with a claimed 320LPH :O

I'm even more dubious now, and would certainly like to see these tested independently.

The problem is all manufacturers claim/rate @ different levels, voltages, pressures etc. It's always hard to compare upfront.

I try to work towards 70psi as a "marker" and using 14v. Of course sometimes you have to improvise as figures are only supplied with 13.5v or 14.2v etc.

Anyway the reason behind "70" is the base. Which is what, 38-42 psi.

So +25psi of boost is 60-65psi. Round it off to 70psi and it should cover off most situations, or if you wanted to bump rail pressures running say 20psi and get a bit more out of injectors.

its about time they did something, the previous pumps are JUNK, these days I won't even let a car on the dyno if it has a walbro pump.

No matter what happens they allways eventually fail or they NEVER flow enough. I hate them with a passion they cause me soo much grief.

We put 2 in a supra, and after 3 weeks one just stopped working and it toasted the engine.

Would have to see how this goes, im going to order a few and try them.

I feel your pain mate...

My Walbro has been slowly dying in the arse (less than 2 years old and 10k's) after recent power upgrades - it cannot keep up with 250rwkw@14v :down:

There seems to be people happily running these numbers with them (e.g. dyno results thread)... but also just as many with problems these days!

Fuel supply is not something I want to leave up to chance... god knows what damage has already been done (hello knock!)

P.S Just purchased one of these 300lph Deatschwerks to replace the Walbro:

It flows the same as an 044 and is a drop-in, in-tank replacement at a lower cost.

Anyone got any first hand experience with these new pumps???

Also would the Deatschwerks 300lph pump support a 400-450rwkw gtr on e85???

Not a hope, considering you will need 1000cc injectors at a minimum, x6=360lph, but that flow is not at the pressure that you will need (approx 70psi)

Got my new pump today... looks little. but where impeller is is huge... wont know how it goes till next dyno run next month

Possible you could test it? Similar to the link earlier???

      R34 RB20DE NEO + T ONLY

      By Sxnjeet · Posted

      Hello, I'm trying to make this thread basically the thread with all the answers to common questions regarding specifically the RB20 DE NEO + T engine, that comes in the R34. Answers will and only should be provided by those who have done this conversion or actually have some relevant real life experience please. Please feel free to ask questions in the comments if you have any so other members can answer. I feel like this thread is really needed, especially with more Americans buying (unknowingly going to regret it too) rb20 neo r34s. My first question being - What do you guys use for tuning? I have purchased a haltech elite 2500 Plug and play kit for the rb25det NEO because the ecu plug is the same, but I am unsure if any of the pins would need to be repined to match. Second question that I see asked very often - After this conversion, did you install the boost solenoid/ actuator? I see many people doing a + T setup on their rb20 NEOs while running stock RB25DET NEO ECUs with no tune. I am wondering how they are going about doing that and consistently abusing the car because many of these people have had these untuned setups running for a very long time. That was my original plan, but my engine cuts out at 5 psi of boost using the stock ecu with no tune and no boost solenoid/actuator.

      interesting. ive read and heard otherwise over the past year. ive been doing this +t conversion on a rb20 neo using all oem rb25det neo parts including the ECU, and im having engine cut out issues when I hit around 5 psi of boost. Everywhere/everyone ive asked has told me its because I never wired in a boost solenoid/actuator to the ecu, so the ecu isn't getting the right signal once it hits 5 psi of boost, causing the engine to get shut off.

      Something strange is happening. I didn't touch the car since we last spoke on the forums. Yesterday was the first day of good weather, so i took it out for about 2 hours. It started up on first crank every time about 5 times total. I literally didn't do anything to do the car.

      I purchased this one. Very well priced and works great. I was rough with it to see if it will last and had no issues.  Teslong Two-Way Articulating Borescope with Light, Industrial Endoscope Inspection Camera with Articulated Probe, Flexible Mechanic Fiber Optic Snake Scope Cam for Wall Automotive Engine Inspect-5FT : Amazon.ca: Industrial & Scientific
