Hi guys

Would appreciate any help to replace my driving fog lights / high beam. Well im intending to put HID on both high beam and low beam. I know for sure that Low beam uses D2R and high beam uses H4 (dual filament for fog light as well). well my question is there are 4 types of H4, H4-1,2,3,4. which one should be picked for our cars ? Im pretty sure it wont be H4-4 coz the current bulb doesnt seem to be a twin bulb type, and it should not be h4-1 either. Regardless, im pretty confused and deseprately needs u guys to help T_T

Your highbeam/fog lamp as they use a single normal H4 halogen lamp. You will need a H4 HID replacement to convert this to HID, similar to the H4-3 unit listed here -

http://www.hid-lightsdownunder.com/service1.html

If you have D2R lamps in your low beam, they are already HIDs. - the low beam is a totally separate lamp in a totally separate reflector.

From what I understand H4-1 is a low beam only lamp (fog light only). H4-3 uses a single lamp with a retractable light shield. H4-4 uses a twin lamp.

my drivers side "top" light has gone out, i beleive the bottom circular shaped bulbs are the fogs/low beam is that correct and the top lights are the low beam/high beam? Don't know what to replace the bulb with, i know it's halogen but not sure exactly what typre of bulb to replace it with.

well, "top" is low beam ONLY...the lower part is high beam/ fog (driving lights actually) ... HB2 (9003) is the one for that high beam / fog light (aftermarket projector however uses H4 instead.) and D2R is the one for ur "top" light which is LOW BEAM ONLY

Sedan was the only model that ran a dual filament bulb for high beam / driving light.

Coupe' ran a H1 bulb for high beam as driving lights were an option that went into inserts in the front bar.

Low beam on both is D2R, unless converted to Halogen then it will be a H1 globe and a little insert fitted to the globe holder.

mate, i run a coupe :), 04 model (not sure if that makes the difference) but i have "driving lights" and "high beam" in the same bulb. because i can turn on driving lights and flash, i can tell the height changing so definitely that must be a dual filament type :)...not sure other models though :)

      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.
