Default R/C 440s without Engine Management? Help!!

I am going to buy a set of R/C 440 injectors from RallyEric. I have an 01 RS turbo with the following specs:
-'91 Leagcy Turbo, manifold, uppipe.
- Custom 2.5" downpipe w/ highflow cat.
- Vortech 4:1 RRFPR
- 5Zigen 2.25" Catback exhaust.
- GReddy Integra Drag FMIC (28"x11"x3")
- 2.25" Intercooler piping.
- Blitz Super Sound Dual Drive Blow Off Valve.
- '91 Lagacy Turbo fuel pump.
- Autometer boost, air/fuel and EGT gauge.

If I just plug in a set of R/C 440 injectors will my car run ok? I mean will it smoke? Will it idle lumpy? I have heard previously that 440s are the biggest injectors you can run without having this problem. Is this true. I will eventually get a TEC-II but I want my car to be as reliable as possible until then. Please any insight is greatly appreciated.

would it work if you cxould lower the fuel pressure enough?

you would have to make it much lower then stock I assume correct?

Well, I am SURE they dont work with our MAPS, because there is nothing we can use to change the signal the ecu gets (Like the AFC does for a MAF sensor), and clamp it to 4.8v because of the boost. (Does that make sense?)

You should have a high flow fuel pump, too low of a pressure will make it unhappy
also, even with a stock pump Im sure the lowest of pressures would make more problems than it solves. I dont remember exactly but I think we went below 25psi when trying the 370cc's?
Still didnt work...

ALSO!
Why buy the saturated injectors (high impedance) that the stock ecu needs, when you could use that money towards peak and hold (low impedance) injectors that most aftermarket EMS's run. They are much better. So... Just do it right the first time.

might as well just save up for a tec2 kit with 550cc injectors already in it and get some tuning help from shiv. the more and more i think about it, the more I would rather just use a tec2. save 500 on boost controller, save 400 for injectors, save 450 or so for not needing a J&S, and save a hundred or so on RRFPRs. thats already ~1450 bucks. might as well put in another 1k and get the tec2 unit and forget piggy back crap.

looks like its time to save some bucks.

IMHO, I would go with the Tec-II if you are running a MAP setup. It just seems like you don't have it as easy as the MAF equiped cars. Besides that with everything I have bought over time I could have just saved up and bought a TEC-II which would have allowed me to do anything I am doing now plus some.

exactly my point bill. im done playing with the fuel system. im just going to go back to 5psi, keep a 4:1 running and just save up for shiv's setup. i also forgot the extra ~200 for an ITC that will allow you to advance timing and also who knows how many hundreds of dollars you can save on gauges. maybe if i get the tec2 setup ill get rid of all the gauges and crap and go back to the stock sleeper look.

What is considered a sleeper look in Andrew terms?

In any case it might be worth it. I am thinking of getting a Tec-II just so I can learn more about cars and be able to tune them. Sounds like a lot more fun to me then messing with stupid leaks, and what not.

hahahah...me talking about a sleeper look! hahaha. how did the conversation go before?

Bill: "Its loud"
Me: Whats loud?
Bill: the whole car.

hahahah


well mabye if i didnt have gauges they would just think the turbo is an intake and the exhaust is just a stupid thing to have for a NA car.

Someone posted something similar to this about some people using bigger injectors and an AFC. The person said the injectors were twice stock and they used the AFC to lean out -50%
I dont know since you do have a MY00 and an AFC doesnt really do much. not sure about any of this.

Can't the S-AFC adjust the MAP signal? If it can, then I don't see what the big deal is. I'm running 390cc injectors on my MY98 and the S-AFC is being used to tune. It runs pretty well with only the first 15 seconds of a cold start giving away the fact that it's not stock.

mcgyver is running only 380CC injectors, and no engine management except for a Weapon-R RRFPR. He seems to have no problems, of course this is a 98RS (MAF equiped).

I am going to put in 440cc's as soon as I get my damn SFMU working. Once again though I have a 99RS (MAF equiped). I also have a S-AFC to tune in the Fuel amount and a Vortech SFMU to adjust fuel pressure (still trying to fix problems on it).

Here check this link out for more info on MAP equiped cars, with a S-AFC and bigger injectors.
