What size injectors are stock in 2.3l Turbo and what size should i run if im looking to get 300 hp out of the engine. Thank You!

what kind of car do you have? If its a thunderbird tc than im pretty sure the 85-88's have 35# injectors and the should be fine to 300 hp if you uprgrade your fuel pump and get an adjustable fuel pressure regulator. http://www.forced4.com/index.html has a great one for the svo and tbird. Good luck, im trying to get my car to 300 hp too.

The stock brown tops are rated at 35 lbs and would have to run at 100% DC to accomplish 300 hp. I would not run those injectors they are to small. You would need 55lb injectors at a 80% DC

Great but sorry for mabey asking a dumb question but how do i turn down the current to the injectors or does the computer do that for me.

Steeve buddy how goes it. T bird here is a simple senerio. The ecm controlls the injector pulse with or duty cycle. The injectors are turned on and off and measured in MS milli seconds. There are alot of different ways like pulse and hold (etc) Basically the ecm takes in data from all the sensors and makes a decision on how long the injector is on. Basically the O2 keeps the mixture at the right ratio. STICHOMETRIC RATIO. At 14.7 the mixture is considered perfect to an extent. That is 14.7 parts of air to 1 part of fuel. The ecm is the brain and the input sensors tell it what to do. This is a very simple explination. If anyone wants to chime in go for it. TOM
