What size injectors to use?

[FirstCarIsA GSX]

I am looking to purchase injectors to go along with my new Evo 3 Big 16g. I am looking to try and get between 300whp-350whp and the tune will be done by RRE. I currently have 550cc injectors and am looking to upgrade, so what size should i go?

Find a way to tune them, 650c or 850cc in your set up, get link and run as big as you want.

i would probably get a set of 950's there is not much of a price differance between 650cc and 950cc and the bigger you go the better so you dont have to upgrade them again in the future (with ecmlink) i think your limited to 550 to maybe 650cc's if you have a safc?

well i wont be using ecmlink because RRE will be tuning the car and the data logging and stuff will be done with evoscan. i was thinking 850cc's but i wasn't sure if they would be overkill or not enough to max out my turbo

You know, instead of spending tons of money on Link, you can just purchase a Tactrix Cable and tune your current ECU just as much as you can With Link, Minus buying an Ecu ($200+/-), Link ($150/600). And ECUFlash (What you'd tune with if you tuned your ECU) is free minus the 160 dollar cost of the Tactrix Cable (unless you buy used) is Speed Density Native (Which costs 545 bucks Minimum From ECMLink) (Map Sensor, not MAF). All you need is the sensors to convert over and newbish wiring experience. But to each his own.

Back on topic. In my experience I've seen people use 750cc Injectors on a Big 16g for Max Efficiency of Turbo and Injectors. Just so the Injector isn't maxed out for the boost levels being thrown at it. Since Maxing out injectors isn't really a good thing. I've seen great results from the Evo 560's personally and I'm about to start tuning for 850's on my 20g.

I honestly say 750cc's for a big 16g and tune the hell out of it and enjoy your lovely stock looking, Ass Whoopin, Turbo Setup!

Maybe here you will find some info too:

750cc looks ok for what you want. But I would take 850 or 950.

I dont see the point in what half these people said, unless you want a shit idle, or you plan on doing a huge project down the road to get some serious numbers and what to save your self buying another pair.

@ anything more then 700cc's for a 300-350whp setup.

I'm going with 1000cc and a 255 lph pump for my big 16g. If you have a way to tune for them that way you won't have to upgrade the injectors for a while.

880's and a 255 walbro fuel pump. I've had them for a little over a year and they idle like stock. I got them for cheap from the classifieds.
