injectors for a t28 powered dc4

I am in the process of turbo'ing my dc4 integra and am about to order my injectors

Bit confused as to whether or not I need to get the 525cc ones? Or can I get away with the 440's?

The turbo is a t28 non bb if that helps

thanks for any input

440's will suffice...no problem!

would s2000 ones fit a b series motor?

thanks for the input ProECU just needed some reassurance that they will be fine :)

not sure if s2000's will fit, BUT REST ASSURED 440's will be fine.

injektd - here's a calculator to work out what size injectors you need based on expected horsepower.

http://www.rceng.com/technical.htm#WORKSHEET

At 250hp with a BSF of 0.65 and a Maximum Duty Cycle of 80% it comes out to 537cc/min.

Thats calc is only a guide...

like I said before, 440's will do if he can get a set cheap, otherwise your 550's will more than do the job

They will. If you look around you'll find a thread where fitment is dicussed and confirmed in detail.

S2000 injectors mount into B16A fuel rails so you'll have to source one if you want to go that way if not just get a set of sard or whatever to suit it.

i'd go 550cc from rx7 series 4, better to have headroom than none. what if later on you want more boost??? buy new injectors again? when it comes to fuel systems i like to over kill to make sure i never run out and dont have to worry about upgrades again.

The man has said it 3 or 4 times now...440 will be fine for t28!
Go 440!

Sorry, I didn't know he was your man.

440's will be fine, if you don't mind turning up fuel pressure and don't perceive any future upgrades.

Personally I'd stick with RC Engineerings calculations. YMMV.

you wont need to increase fuel pressure either.
