I heard the jap model S15 (manual) injectors which flow 480cc can fit as a direct swap into the rb25det, can anyone verify this? If so would it support up to 270rwkw with fuel regulator? I have all other supporting mods.

Apparently other engines to share this style of injector are the RB25DET, the 1JZGTE, 2JZGTE and the VG30DETT.

Yes they are a direct fit. So are USDM Ver 5/6 STi injectors (a little easier to find, usually go for about $USD150 per set of four). The toyota "J" injectors are low impedance, so no good without a ballast resistor. Mazda FD3S primary & 20B injectors will fit with Sard type collars.

So you indeed have some choices !

I looked into doing this once, but I would have had to buy 2 sets of injectors (non of the wreckers would split them) then I was going to get them cleaned and flow tested and use the best 6. Total cost was around $600 (for second hand injectors) - I then decided if I was going to pay that much I would rather spend $700-$800 for new ones rated at 550+

where did you get them for under $800?

      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.
