Hi all,

I'm trying to id the parts circled in the pic below.

I think green is the fuel pressure reg?

Cheers

Green is indeed the EFI pressure regulator.
Red is the EGR valve, Exhaust Gas Recirculation.
Purple is either fuel supply or fuel return.
Blue is a thermo valve for a vacuum source?




I think!

Thanks Nissanman

The egr valve has a vaccum hose on it. what should i connect this 2.

will the standard fuel pressure reg be ok for a turbo?

That fuel barb is not the return or supply, these are seperate, is there somewhere else fuel needs to go or can I block this off?

Vacuum to brake booster possible?

if you have feed and return there is no need for that Tee that i can think of. it would normally have been pipe, so a straight bit of hose end to end would do.
that little sensor, just after the throttle body, could??? be an air temperature sensor of sorts.. why it has a vacuum line to it, not sure, unless it's for cold starts.
the Z18 efi had a sensor right after the throttle body on the intake for that same reason.

the last 2 things are

blue = extra fuel jet

purple = extra fuel jet feed

ding! ding! ding! i won the million dollars!!!!

if you arent going to use it then pull it out, or plum it up, put a plug on it and run the wires back into the loom to make it look propper, you dont want no po po telling you that your missing a vital senser or some Krap!

i think that the reason for the jet is becaue of the poor ecu that was used on these engines, i mean if you open up the original trottle position senser you'll fin that it is just a 2 or 3 position switch (closed, mid and open!)

also I think that the jet is in backwards. if you pull it out you will see a 25mm long shaft with a tiny nozel in one side, i think it is supposed to point away from the butterfly

hope this helps

RED - EGR. I did away with this
GREEN- FPR - Fuel Pressure regulator
BLUE - Cold start injector
PURPLE - Cold start injector fuel feed





Have a look....
