Just because "it will get the job done for xx" doesn't mean its ideal or good.

I typed up a giant post about why I think it would be stupid, but don't want to clutter this thread. Even found a flow chart for the pumps. If you're really interested, we can discuss.

We give noobs a hard time about half assing things. Here we have a guy that wants to do everything properly and you're telling him to half *** it.

Not a requirement for who knows how much power/flow? Oh that's right "just crank it up dawg, when you start to run out of fuel and leaning out, then upgrade". I'm sorry, I'm not bashing either of you, and personally have done it myself for a short while (on my 1st turbo setup), but I just wouldn't recomend that.

Its kinda like we were all led to believe before that the 8-10psi fm voodoo kits are "ok" on stock fueling components til most started reporting major lean-ness and maxed out injectors even at 7psi

Hmm, okay. I didn't mean to start a flame war or anything, I was just always under the impression that its not half-assing it on a stock fuel pump if your running stock pressures. When I went MS, I bought a NEW oem fuel pump at that time. It wouldn't have costed much more to go with a Walbro right away, but from the information I gathered at the time it wouldn't be needed for my purposes at all and it would be louder.

I'll take your word for it though, and start looking for a new pump for my 1.8 build. I want to make the car e85 capable anyways, and know I would most likely need more pump for that.

for e85 I would suggest looking at the dw lineup, which cost about the same and work silently
Just ordered a dw200 myself

Stock pump if fine for a stock motor (for NA at least, not sure about you NB ****). Unless you need a new pump, then upgrade while you have it out and do the rest of the fueling system while you're at it. I made the mistake of doing piece by piece. OP mentions built motor, so use bigger pump!

OP, VooDoo box is scary stuff. There are reports of cars going really lean using stock fueling components.

OP, since you have a '99 with it's returnless fuel system, if you want to go bigger you will most likely have to run a return line.

But from my understanding you shouldn't need to do that until you go for some BORG WARNER S366 action.

DW300, best pump ever made. especially considering that used fuel pumps have almost no resale value.

Wow! now thats a debate!!!
Budget for a pump here is not really a issue, i just don't want to go too overkill.
i did mention a built motor, but not now, because THAT is a budget issue haha!

i'm changing the pump and regulator anyway, i had a few report of pressure lost last summer, plus, the pump have 10XXXX miles on it, i'm there, why not put up a few bucks more for a good, high flowing, reliable pump!

The labor here is also not an issue, i have all winter + lift and all equipment i need!

So i'm kind of into the 255HP, it's not too expensive, so we got that one on the list! Now, knowing that i'm changing the regulator, could the extra labor of making a return line w/ Adj. regulator would be worth it? If so, what would be the best way to do it?

Yes i know, i'm asking alot of question, but my tuning experience is a bit low!

if you're going for big power, might as well convert to return style. otherwise the 255hp will easily get you to 300-400

Using a bigger pump on the NB (DW300, WB 255, etc), does it require a different FPR? Or will the stock one suffice? Also, any issues with running the bigger pump on the stock ecu (for when I go to OBDII compliant mode)?

Sorry for the OT, just got excited about the fuel pump discussion.

Very nice build!

OP, you're on the right track. If you know you're gooing above 250whp and building the motor, then yes, it won't hurt at all to start getting your supporting mods done now.

I run
- stock 91 FPR
- stock 91 fuel lines
- stock 91 fuel filter
- stock 99 fuel rail
- stock fuel filter
- Deatschwerks DW300 fuel pump kit
- Injector Dynamics 1000cc
- Gates Barricade 225psi fuel hose (Part #H344A/H344A/H349A/H354A at NAPA)

Basically everything stock except pump, fuel injectors and some good fuel hose.

I seem to remember where someone tested a factory NB pump and it had trouble keeping the pressure up @ 7k running N/A with stock injectors.

Fuel Pump - Miata Turbo FAQ

Vlad is right, the $80 wally pump is a no brainier. The 190HP should be fine, and IIRC the amprage draw isn't that much of a hit compared to stock.

Will the amp difference of the 255HP cause trouble?

Leonid, thanks for the info! Are you running a return-less system with that 99 fuel rail?

Joel, treadstone has a fuel pump wiring kit for $30 that I may try to avoid any power issues.

People just don't realize that some good hose can change the world...

I'm about 98% sure Leonid is running a return on his system.

I've actually got a complete fuel line from a friends NB that will end up in my car, once I figure out how to plumb it in. The NB returnless system is a disaster with the regulator in the tank and no vacuum reference.

Vlad: How did you run your fuel systems in your previous NBs?
