Bigger injectors

Post by **vboyq** » Wed Apr 02, 2003 7:39 am

If i were to buy bigger injectors 550cc injectors would that affect daily driving mileage or only open throttle driving, also how much mileage can be expected out of the 550cc injuectors on about a 10psi daily driven t25?

Theoretically, yes your fuel economy will fall off. Reason being that the ecu can't control the larger injectors as precisely. Fuel economy will vary widely depending on the driver and the condition of the motor and electronics.

would it be a major drop off?

get a z32 maf w/plug. And get your ecu reprogrammed or an afc

What will probably kill the fuel economy most of all is that you will want to get on it more. If you stay off it you should run about the same fuel economy as before.

So then it will noticeably affect the fuel until i drop the hammer?

NO, he said it will get worse when you drop the hammer. More boost=more fuel(hopefully). Makes sense right?

yeah it does, but what asking is during normal driving w/ partial throttle, will it significantly affect the gas at ~10psi

Normal cruise driving with light throttle, you won't be in boost to begin with. Does that answer your question?

will the ecu need to be reprogrammed to utilize the larger injectors?
