Big Injectors Verses Fuel Economy

[gtst4d]

Rebuilding my motor and wanting to up the power to high 200rwkw. I am looking at getting some bigger injectors but i was wondering what these would do to my fuel economy as my car is a daily driver.

Questions are;

What i really want to know is it posible to have 280odd rwkw and still get any where near the 500km out of a tank that i get on long trips and 420 odd around town.

What size injectors?

I am also not sure of what turbo to run i was thinking about the GT30 just not sure how laggy these are ?

Is it possible to have these sort of figures and have something that has a bit of grunt down low cause i dont want to be waiting till 4500rpm till it comes on boost.

And last but not least are these cheap IC that just jap is selling able to flow these figures that i want .

If anyone is able to help with any of these questions or ideas that can get me to 280- 300 rwkws it would be great. :confused:

pwer only comes from the fuel you burn, so more power = more fuel consumption.

the bigger injectors by themselves would not change your economy, everything else unchanged, they would just be open for a shorter time and let the same amount of fuel through. However, your economy is greatly controlled by your right foot, go easy on the accelerator, and it'll be heaps cheaper to run....

Thanks bigmicky so under normal driving miss daisy conditions by the wife it shouldent be to bad.

Any help on injector size or turbo setup that isnt to lagy anybody

Thats not always true, bigger injectors are less efficient at firing smaller amounts of fuel. I had a sr20 with 660cc ish injectors and could still get 440km/tank. Driving it hard i went through half a tank in 60kms tho.

280-300rwkw hey... that's plenty of power.. you mite need to consider going tuff internals like forged pistons and other things.

but yeah.. more powa more fuel.. your engine will always go thirsty after every grunt of powa.

750cc is recomended for 300rwkw.. and 044 fuel pump . aftermarket computer and alot of other things but most importantly.. DOH-- alot of DOH involve.

good luck.

Yeah tell me about the DOH, got forged pistons and rb26 rods , still waiting on engine bearings. Just need to start finding the right things to bolt on. And DOH.
