Installing 1000cc injectors in the Honda V6

Contributed by: enginebasics.com

Turbo charging this motor is going to mean more air going into the motor, which is going to require more fuel as well.   To accomplish this we are going to upgrade the fuel injectors to 1000cc injectors.  The Injector Dynamic injectors are just an EV14 style Bosch injector that was chosen to meet the fueling needs of this particular build.

This should provide us plenty of fuel once the turbo is added yet still maintain a decent idle.  While the OEM injectors are a Bosch type injector, the injector clips don’t fit on the EV14 style injector.  Bummer right?  Not that big a deal though, as it just means a little bit more work for us to wire in the new injectors.  It will require that we remove the pins out of the old injectors clips and cut off those clips.  We will then crimp the new injector pins on and shove the pins into the new injector clips.

**WARNING**

1.  Be careful to keep the pin direction the right way as you insert it into the clip. (most will only clip in one way so it should be dummy proof but some styles of clips are not)
2.  Make sure you keep the wires in the same order with the 12v on one side and the ground on the other.  For our example the 12v power wire was yellow with a black strip, while the trigger wire (ground wire) was each differently colored for easy wiring (thank you Honda).
3.  Be sure to get a solid crimp on the wires with maximum contact being made with the pin connector.

To give you an idea on time, it took just over an hour to carefully remove all the old injectors clips, cut their pins off, crimp new pins on, and slide them into their clips.   If you’re nervous about doing this than there are companies that will make plug and play injector clip adapters to make it a true remove and install type job.

Now that we have the electrical taken care of we can start working on actually swapping in the new injectors.  Most injectors come with a lubrication past for the O-rings.  If your injectors didn’t come with any sort of lubrication than try to use just a touch of assembly grease/lube.  A little goes a long way in this case so lightly cover the o-rings and just put enough that they will slide into the injector bosses without ripping or tearing up the gasket, and also so they will stay soft and not dry out and rot.  On a turbocharged motor this is one area you will see very small boost leaks at times when performing a boost leak test if the o-ring sealing the injector into the intake manifold is not seated properly.  The other leak happens at the fuel rail itself.  This leak is MUCH more dangerous and could cause devastating damage if raw fuel is leaking onto a hot motor or hot exhaust headers.  Make sure these gaskets slide in and seal by always checking for leaks post installation before firing the motor up.
