Hey guys im going to be removing my injectors this week and just wanted to know the best way to get them out. As in do i have to take the plenum off or is it possible to get them out with it on. Also if i have to take the plenum off, can you get a gasket from nissan australia for one?

By the looks of the r33 injectors, all i have to do is get the 2 screws out and pop the injectors out.

Car is an R33 GTST.

Thanks, Mike.

Not that simple I'm afraid.

You can get them out without taking the plenum off but it usually takes the same amount in stuff around time if you do it that way anyway. The injectors need to be removed in a specific way. Take the caps off, turn them sideways (so they face the end of the rail) and then grab a LARGE screwdriver, place it between the base of the plug and the rail....make sure t's right in there...then twist. Out she pops. Repeat 6 times lol.

The tricky part is on re-install....you MUST drown the injector seals in lubricant and lube up the injector tubes (in the rail) otherwise you risk pinching the o rings. Don't forget to swap the old o rings to the new injectors or get some new ones. Place the injectors in their respective hole and push hard....if lubricated properly they should POP into place.

The gasket shoul dbe able to be re-used for the plenum if you unbolt it....it is made of rubber so give it a LIGHT coat of sealant on re-assembly.

Simpler is to simply remove the throttle body (after removing X-over pipe), then remove 3 bolts holding the rail in place.

I think, from memory, you need to pull some of the plumbing above #1, #2, but that will be obvious when you are doing it.

      My guesstimate, with no real numbers to back it up, is it won't effect it greatly at all.its not a huge change in position, and I can't see the air flow changing from in turbulence that much based on distance, and what's in front of it. Johnny and Brad may have some more numbers to share from experience though.

      Which solenoid? Why was it changed? Again, why was this done? ...well, these wear..but ultimately, why was it changed? Did you reset the idle voltage level after fitment? I'm just a tad confused ~ the flash code doesn't allude to these items being faulty, so in my mind the only reason to change these things, would be some drive-ability issue....and if that's the case, what was the problem? Those questions aside, check if the dropping resistor is OK ...should be 11~14 ohms (TCU doesn't throw a flash code for this) ~ also, these TCU designs have full time power (to keep fault code RAM alive), and I think that'll throw a logic code (as opposed to the 10 hardware codes), if that power is missing (or the ram has gone bad in the TCU, which you can check..but that's another story here perhaps).

      Question for people who "know stuff" I am looking at doing the new intake like the one in the picture (the pictured is designed for the OEM TB and intake plenum), this design has the filter behind the front bar, but, the filter sits where the OEM duct heads into the front bar, and the standard aperture when the OEM ducting is removed allows the filter to pulled back out of the front bar into the engine bay for servicing, a simple blanking plate is used to seal the aperture behind the filter This will require a 45° silicone hose from the TB, like the alloy pipe that is currently there, to another 45° silicone hose to get a straight run to the aperture in the front bar Question: how will it effect the tune if I move the MAF about 100-150mm forward, the red is around where my MAF is currently, and the green would be where it would end up Like this This is the hole the filter goes through  Ends up like this LOL..Cheers

      Despite the level up question, actually I do know what that is....it is a pressure sender wire.  So check out around the oil filter for an oil pressure sender, or maybe fuel pressure near the filter or on the engine. Possibly but less likely coolant pressure sensor because they tend to be combined temp/pressure senders if you have one. Could also be brake pressure (in a brake line somewhere pre ABS) but maybe I'm the only one that has that on a skyline.

      Pull codes via the self-diagnosis procedure. As far as I can tell this is just a sign of transmission issues but not a code unto itself.
