which injectors

16bit · Postby **16bit** » Wed Oct 31, 2012 4:45 pm

Hello All.

I am looking to delete the 5th injector in my supercharger system and opt for 4 bigger injectors.

Does anyone recommend a particular brand?

I have been recommended these http://www.miataroadster.com/fuel_injec ... 62736.aspx

Hoping for some input from people who have got aftermarket injectors and boost.

Thanks.

I think it will depend on your power goals?

I know people seem to doing ok with the RX8 Injectors at 200odd whp.
They are 450cc.

you have probably asked a second question for me!

i am only producing about 200whp at the moment but want to future proof for 400 crank hp.

i have used a few online calculators and they say to aim for about 775cc injectors at 80% duty cycle.

is it ok to run such big injectors while I am making the lower power figure?

Also I have read numerous times that the spray pattern is different on RX injectors, this should be confirmed prior to purchasing any.

They are different but they work fine.

Just buy ID1000's and be done with it mate.

+ 1

You will get OEM like idle even with the 1000cc's

Or buy FIC as linked above from miataroadster for less $$ and get great service and the same (bosch EV14) injectors in a better selection of sizes. FYI I am running 775, that should be fine for 400 CHP.

Cheers,
