[Jonnygtr24]

hi my name is jonny, this is my first time in this forums..

i got a question about SARD fuel injector and i want to know how much fuel does it waste?

i heard that upgrading bigger injector can drink alot of fuel. im planning to get it fitted on tuesday coming up.

My big question now, i want to drive it normal but dont wanna accelarate hard how much fuel does it waste compare to the rb26dett stock 550cc stock injector?

THANKS GUYS!

For a start, stock injectors are 440cc. If you put 650cc injectors in there you will have it running pig rich, if it runs at all. You need a programmable ecu to accomodate the larger injectors.

If you tune the ecu for the injectors, it shouldn't use any more fuel for the same amount of power, just that the duty cycle will be lower, ie open less.
