Can We Put The Fuel Pump Upgrade Thing To Rest?

[TUF250]

I had a thought everyone. I have been researching fuel pump upgrades for my R33. There are sooooo many thread that I have read through. I thought maybe someone with the know how could fill this in a it could be put in the FI guide for future users.

I was thinking a list of the common fuel pumps that bolt in, direct fit.

Have a link to the fuel pump re-wire thread

Also to have the flow rates and how that equates into rwkw goals for each of the major pumps (ie. standard vs 040, 910, walbro etc)

Maybe like this.

Standard R33 Pump - xxxLPH - xxx rwkw max

Bosch 910 Pump - xxx LPG - xxx rwkw max

etc

I would be very interested in this information and im sure others would too.

Just a thought

All people need to buy when upgrading the fuel pump is the Nismo intank.

Will cater for 80% of forum members power goals.

Yeah but its $500 without fitting. Not everyone can justify that.

^^ Thats is somewhat valid, however, it will be like the oil discussion - Some people run the cheaper stuff - and there is nothing wrong with that, just personal choice.

I'm not saying only the expensive stuff works - But it will always bolt in and do the job (hence the price)... Unlike some other brands.

I myself have a Bosch 040 - slight adjustment to fit, but works fine for my application.

Standard R33 Pump - xxxLPH - xxx rwkw max

Bosch 910 Pump - xxx LPG - xxx rwkw max

etc

I would be very interested in this information and im sure others would too.

Can be found by using the seach button, or simply looking up the specs from the manufacturer.

i know that it can be, I have looked through alot of threads, I did also find the 'fuel pump bible' thread which was quite good. I just thought if it could all be compiled and put in the FI guide it might stop alot of new threads being started. Just a thought, I have learnt what I need to know so it dosnt matter to me anymore thought it just might make things easier in the future

Isn't there some kind of WIKI plugin for this forum? It would be the ideal way for information to be collated and allow for easy updating. especially good for these kinds of things...

TUF250 - the problem is that everyone has different ideas on how to calculate fuel flow and how much power a pump will support. Yes a certain pump can support 300rwkw but can it also have good fuel control and be able to run 10.5:1 at peak torque when it needs to? or is it at 12:1.....who knows? It is still best to tell other ppl on the forum what your setup is and ask for their experience and opinion. 9/10 you'll get the response you are after, other times I am just tired and angry

Tomei drop in replacement, comes with filter all sorts of BS... GTR pump "may" be good, but remember it's old.. All electrical motors wear out, bearings seize up, etc.. ra ra ra..

It's a 10+ year old car, might as well give it a new fuel pump.. that's my justification.

As for Bosch 040, fantastic pump, but CBF chopping the OEM bracket and creating new mounts, etc..

As I get older, I become more CBF, bolt on/drop in replacements are the way to go, less of a head fark

So I can justify the price there...

Tomei pump drive to the red light stays on

Bosch pump drive when the light starts flickering and shet bricks because you have no idea when it will stop sucking up fuel

how the f**k is this going to "put the fuel pump thing to rest" ??

if you cant decide what fuel pump meets your needs and where to buy it and install it please do not reproduce

[TUF250]

calm down, I was only offering a suggestion as opposed to attacking people. I just thought it might be a helpful tool. If not then it dosnt go ahead, I was jsut trying to contribute.

Question for others. What is the recommended limit for the walbro unit (the common 255lph one i think it is?) how much performance will it flow over the stock unit?

[bodge]

l have a R33 GTST with a RB 25/26 combo and is making a "claimed" 380RWKW, although in my personal veiw it has much less. Anyway l am running a standard in tank GTR pump that has been wired using a relay to get a consant 14.5 volts and this setup is claimed to be good for about 400 RWKW.
