I am running a fm turbo kit with a gt2560r turbo and a megasquirt. I have a completely stock engine with stock injectors. When I was getting it tuned, my tuner said I ran out of fuel at around 5500 rpm. He recommended a walboro 255 and a fuelab fpr. I looked at the fuelab website and I'm not sure which model to get. Does anyone have any suggestions?

 

Find a tuner who actually knows what he's talking about

 

Buy flow force injectors and be done with it.

 

If you haven't figured it out, you're getting short snarky responses because this topic has been discussed extensively here....... Search and you'll have your answer

Spoon fed pointers:

As mentioned your injectors are too small, but you don't say what HP you're aiming for so not enough info to really guide you here.

Stock fuel pump may be plenty, again HP dependent

​​​​​​Walbro 255 is too big and will out run your stock regulator

Stock regulator will support enough HP for you to throw a rod.

 

He tunes a few of the formula drift cars so im gonna trust he knows what hes talking about... but thanks

 

Must resist..... Urge...... To bash formula drift "cred"

This guy doesn't know Miatas, or tuning because if he was actually watching his injector duty cycles he would know he was running out of PW at ~160hp..... Pumps and regulators don't fix that.

 

He makes engines run over 1000 hp and high rpms for long periods of time.
He has experience with miatas, but since you say he doesnt. what should I do for my fuel system set up starting with the tank to the injectors? thanks

 

Tell us how power you want to run first.....

I'm sure you think he's great, but his direction to you clearly shows he either doesn't know what he's doing or didn't take the time to research the common catch points.

 

I ran out of fuel at 5500rpm and I was making 201rwph. I have the flyin miata kit with 8psi on a gt2560r i dont have a target hp I just want to be able to rev it up all the way now. Eventually I want to run flex fuel.

 

I would encourage you to stop posting in this thread. Like now. Its going to end poorly if you continue to do so.

Go here and start an intro thread: Meet and Greet - Miata Turbo Forum - Boost cars, acquire cats.

Tell us about yourself, your goals, your car, your mechanical ability, your cat, and your experience with other platforms. We are very visual people and appreciate pictures.

This will go a long way with helping make you welcome in our dark and sticky corner of the internet.

 

There's lots of info around this site that would hint to you that that's about where the stock injectors run out of capacity.

If your tuner thinks you're only running out of pump, then he's not looking at injector DCs. This is scary. Don't blindly trust anyone who has no financial stake if your engine blows.

 

Is there an injector or size that you recommend? Is a rx7 turbo injector a choice that I have?

 

Flow Force NA/NB Miata 640cc Injectors with PNP Kit ? Flow Force Injectors

You should buy those. But this is in a lot of threads on the site. It'll work out better if you read the DIY turbo section a lot more, and let this thread die.

Everyone here gets pissed when they see some tuner leading someone down a silly path.

 

Dude, I mean really? Let me spell this out to you, we don't spoon feed people here, you're supposed to search on your own, then ask intelligent questions if you don't get it. This isn't a suggestion, it's a requirement.....You won't last long here if you don't follow this simple concept.

I actually spoon fed you more than I should to try to jog your mind in what direction you should focus your research. Do me and everyone else a favor and Just copy and paste " rx7" injectors into the search bar and see what pops up.

 

Thanks for not being a **********. means alot to a noob like me

 

Tone back the retardation and douchebaggery, it's stinking up the site.
Your tuner is a moron, and the fact that he tunes drift cars makes him that much more so.
No one here is impressed with his/your knowledge and skills if you're both too stupid to realize what is even happening with your car running out of fuel at 200hp.

You want to listen to what EO2K said and start over before people catch on to how dumb and stubborn you are and write you off.

That's if you actually want to learn a thing or two, and not flaunt some "my tuner said so and I'm too dumb to know any better" knowledge which doesn't fly here.

 

Says the guy that attacked me right away... Im new here all you have to say is this isnt the place to ask.

 

you're asking the wrong question, making terrible assumptions, and believing incorrect info, and too stubborn to stop being so defensive about it.

we don't sugarcoat here.

your tuner cannot possibly have missed the pegged IDC's, and no one on earth would ever recommend a fpr/fp on a 200hp miata, that's just plain dumb.

hence the "better tuner" comment. it's not an attack.

 

I mean I said in post #3 what the solution to your problem is. You completely ignored it. Stock fuel pump and FlowForce injectors will max out a stock motor power wise. It was only after you got the correct answer and ignored it that people started completely being dicks. MiataTurbo is the thunder dome and we don't **** around. We are ******** to people that don't search, or ask stupid questions, or don't pay attention to our answers.

 

This is the place where you change your tampon, brush off the tears, and get answers like a man. No sugarcoating.

You can go to one of the drift or stance sites if you want your head petted while they whisper sweet nonsense into your ears
