ok just woundering about injector sizes, i have heard that all b-series are the same size, but i have also heard that D,B,H,F are all the same injectors the only diff is the ecu holds them open longer or shorter. can any one clairify this?

or direct me with a link.
searched but not really finding a good answer.

thanks

 

bump, just wondering

 

there are slight differences in injectors esp across different OBD generations.

I believe all B series injectors are the same but the H injectors are not as they have a larger nozzle to flow more fuel.

The D series I don't think are the same as B and the earlier D series motors had low impedance injectors that required a resistot box to drive them properly.

Probably the best place to get definitive answers is from RC injectors.

I could be wrong on the B and H injectors but I'm 100% sure on the D injectors not being the same for different years. i.e high vs. low impedance injector

 

i'll talk with RC thanks
