As most of you know i just got my turbo in the GS eclispe and now i need some help. if i just use my NT ECU will i bee running rich or lean and if i use my NT injectors would that happen at all.

i would think your ECU would adjust for the new amount of airflow so i dont think thatd be a problem but dont hold me too it, but whats the flow on stock gs injectors? just compare the flow on those to those on a stock gst or gsx and see if its the same.

O boy

I'm not trying to talk down to you, but honestly, if you didn't know this kind of stuff, you had NO business turbocharging your car until you did. Think about it, now that you're turbo you are sending in gobs of air that your fuel system can't handle. If you did upgrade your fuel then great, but now you have no way of monitoring it. Even if you can monitor, do you have the tuning equipment to make necessary changes? Without the proper turbo setup your car will be toast. I hope you work it out before it does. Good luck

yea i didnt even think of fuel either you should also check on how much your fuel pump flows vs a turbo model fuel pump, and i would highly recomend getting something for tuning like crunchy said so you can monitor all this stuff

You obviously won't be running rich. You need to get some sort of tuning device and upgrade your injectors, because chances are you will be maxing them out if you run any type of boost at all.

i am gonna be running minimal boost for now i got gauges and all the stuff to read fuel and air and i got a boost gauge im waiting on a boost controller, i am gonna get stock turbo injectors for a junkyard and i am getting a walbro 255 i think. does that sound about right. i know quite a bit about turbos and how they all work i have evrything in my car i am just waiting on my downpipe and money to get injectors and a fuel pump. i mihg tget a stock turbo fuel pump for now from the junkyard also.

If you can get them really cheap, then go for it. If not, don't waste the time and money. Get the good shit the first time.

Before you even think about firing up that car, please get a logger and a air/fuel controller. I know you have gauges, but that's not enough. A blinky A/F gauge will only tell you is you're WAY off and about to blow the engine.

i am getting 450cc injectors today, and 255 fuel pump and a fuel pressure regulator next week sometime. i am gonna wait on the S-AFC for a little bit cause i think that the fuel pressure regulator will do fine for now correct me if im wrong. i am currently looking for a job so then more mods will come. i dont plan on having my car in operation for a couple of weeks yet so i got time.

You are incorrect that the fuel pressure regulator will fix anything, it will just keep the walbro255 where it should be. Think of it like this, the 450 injectors are like a water hoses and the stock NA injectors are like straws. Even at the correct fuel pressure you will run way off in your fuel trims.

What are the NA injectors in cc's?

Wait a few more weeks, try to find a used s-afc. The regulator will not help this, it will just keep the walbro under control!

91 Eclipse · #11 10-06-2005, 07:50 AM

yeah i found that out last night. if i remember right the stock NT were really low so im gonna replace them just incase. so if i am right this is what i need please add anything i might still need. 450cc injectors, walbro 255 fuel pump, S-AFC, Fuel Pressure Regulator anything else???

crunchymilk55 · #12 10-06-2005, 06:48 PM

a logger should be #1 on that list. But then again, I have no idea what you have and what you don't.

91 Eclipse · #13 10-06-2005, 07:20 PM

well for now i have a completely stock 14b turbo set up. but i will get the injectors first then Logger, then S-AFC, then Fuel Pump, then FPR and that should be good that will run me about 600 dollars so i would have to wait for anyting else. this will hopefully all get done in the next couple of weeks

not to mention i dont even have my license yet. i am 16 but i act 21 and everybody thinks i am but anyway. so i can get my license whenever i want, so just waiting for me to go get them. i have a little time yet
