Injector and Regulator Recommendation
 

So I'm researching the "potential" for upgrading to larger injectors at some point and wondering what you guys recommend. This car was built using a lot of Flyin' Miata's catalog, so obviously I gravetate to their site and see Duetchwerks 700CC injectors for $339 and their AEM regulator for $129. My question is what would "You" do if it were your 1.6L project "daily driver"?

Specs:
Flyin Miata Voodoo2 Turbo kit with intercooler and GT2560R turbo, Flyin' Miata Happy Meal Clutch/lightflywheel kit, Flyin' Miata downpipe and cat convert, MSPNP, Flyin' Miata fuel log, Walbro 255lph pump.

You want ev14's. DW's are ev6. ID or FIC are some of the best. You probably want to stay in the 550 range with that mspnp since it will get harder and harder to control them the bigger you go, with the terrible ms1 resolution.

Injector Dynamics. I should have bought those, not the cheap shit I did.

EV14 is the latest technology. Five-O Motorsport has them as cheap as anybody.

I would not buy from them again, I'd pay more and get ID squirters. I'm pretty pissed.

...And hey for just $150 you can get a set of 4 from Taiwan... Gotta love fleabay...

I'll keep my eyes open for a sale...

Yeah, get Chinese shit. It's not like injectors are important or anything.

Like errybody says, EV14s by either Injector Dynamics (ID) or Fuel Injector Clinic (FIC) and are reputed to be solid units. As Hustler said, the FiveOs can be hit or miss. Do a google search and you will see what I mean.

Another viable injector for the budget conscious are the Denso style 195500-4450 RX8 yellow 450cc units. They are direct plug-and-play so there are no wiring adapters. These are modern OEM units so they will be solid performers with decent spray patterns and they should last for quite a while if properly maintained. Be aware that there are really cheap Chinese knockoff 4450s on eBay, so buy from a reputable vendor. (read: forum sponsor)

I'm not the sharpest hammer in the drawer by any means, but if using properly sized injectors, do you really *need* a regulator? I thought the 90-93 were vacuum/boost referenced already?

I looked at the various large flow ev14 injectors from ID, FIC and five0.
It looks like they use low flow injectors and remove the atomizing plate at the tip of the injector to get the larger flow.
Can it be that easy.... or am I missing something?

What does that lack of an atomizing plate mean?

I guess when the atomizing plate is removed the quantity of fuel flow and spray pattern changes?

Without atomizing plate


With atomizing plate

90-93 OEM FPR is indeed vacuum/boost referenced.

Looking at OP's mod list, he's already wasted money on a fuel log and pump, so why not waste some more on a regulator? :burncash:

Woa Woa Woa... Time out there skippy, I bought the car as is. I'm trying to sort it out from here... I tend to not want to waste money, but will spend the right money on the right parts. I'm not on a terribly tight budget, but I have three car projects going on at once so I need to prioritize what I buy and why I'm buying it.

Just looking for solid advice guys...

Yea, I was kidding... I don't plan to buy crap injectors.

The only injector you should buy are ID1000's. If anyone else tells you otherwise they are wrong. I have used 5 different sets of injectors over the past 5 years and the ID1000's are by far the best ones out of them all.

Pretty sure ID and FIC ev14's are identical. Five-O are apparently the ones that bore out smaller ones to make them larger, etc.

That said I've used ID1000's and they were a pleasure to tune.

Shuiend Even if I don't plan to upgrade from the current turbo setup? What I'm considering in upgrading these parts is that I'll upgrade within the parameters of the components that are currently on the car. I'm using this car as my daily driver to keep miles of my Porsche GT3 and my Dodge Cummins 3500 diesel. So "some" fuel efficiency is important to me.

Thanks.

tickle fight!!!!!1 :pitlab:

Anything is going to be better than the stock style EV1 squirtguns you are running now. Size isn't a super-duper concern with the superior spray patters and the (compared to what you are using now) speed of light latency of the EV14s that are available these days. Better latency = better control, better atomization = higher efficiency. As long as you can control them, its win-win.

I would like to hear more about what Vlad said about the "terrible ms1 resolution" and big ass EV14s

His post doesn't contradict my post. five-o makes a 1000 too and good luck controlling those with a mspnp

when dealing with ID, its different. Its superior

Ok, so its not EV14s that are the problem, its the Five-Os that are the problem. I git it!
