with an fmu, you just bump the fuel pressure with boost. But there's a time that come when the stock injectors aren't able to give you the flow you want. This is when you need to upgrade them for some like that.

has anyone flow tested the stock fuel rails to find out the largest injectors we can run before there is fuel pressure difference between injectors?

ive been searching for a while but i cant find anything on it. running injectors larger than the stock fuel rails can flow will also help u blow your motor quickly cuz one or more cylinders will run lean one day and poof, investment wasted.

does anyone know if mbx motorsports offer aftermarket fuels?

Okay you said to use the connectors that come with the injectors right. So then you just splice or......?

This thread is old, you would splice the wires into the oem harness

Isn't there an issue with the actual spray pattern of the modden Nissan injectors?

Just want to add. As far as I know you can't run these using the stock ecu. Meaning you can't just add these if you have an fmu. You need megasquirt or someother standalone.

Yes, the "super soaker" effect. You get a stream of fuel as apposed to an atomised spray.

I used the factory injector hats which have a knife edge to them to help with this issue.

Only thing this writeup could use is a wiring diagram or a link to one, it may be on the forums but its nearly impossible to find. These injectors are so simple to do, but plug N play is always the best.
