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 -

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 :)

    • Cheapest option, find a NEO head. Put in good springs, decent cams, and send it to the moon. I rev mine to 8600RPM, gets me about 232km/h down the main straight at SMSP bouncing off the limiter in 4th. I've never dared to grab 5th 🥲
    • Gday mate, Personally in my car i run 450kw in an s2 rb25 so also hydraulic lifters and have always run it to 7500 RPM and using some baby 256 poncams with new but stock springs and retainers. While i cant speak on any experience with solid lifters i personally have had no issues with my hydraulic lifters which were just cleaned and set in an oil bath before assembly over 7 years ago. Over 8k RPM is cool IMO and if you are using the stock gearbox or just a box with longer ratios the higher rpm certainly could aid to maintain boost into the next gear as that was always something i struggled with as i have a 3582r also but a hypergear equivalent could aid that issue. In summary i would make a choice on the cam you want to use first then decide which springs and retainers work best with it and then you can toss up if you really need the solid lifters, if the car is mainly street i would learn towards keeping the hydraulic lifters as when installed properly and nothing too hektik going on around them they do the trick.  
    • Yucky. Things haven't gotten any better though. Now you have Emerson and Honeywell pushing these massive DCS/Scada things with proprietary hardware. They're not a PLC, they're not a computer, they're a...distibuted PLCish/DCSish monster of thing, that only they can program because they make the barriers to entry for anyone else so fricking high. And their developers are all located in the third/developing world (and India, in case anyone does not include that place in that category) and there are terrible failings of the ESl variety, of the care and common sense variety, and f**king forget about Functional Safety. Not a one of them has any idea what it means to comply with an IEC 615xx series standard.
    • All of the ECU grounds are to the chassis, the IGN grounds are to the cylinder head and i believe all the OEM body harness are left in original locations, im trying to work out if i can tell if the sensor voltage itself is losing any power to it from the very low ECU voltage. But yeah a manual pressure gauge will help in picking which path to actually chase. Also please dont bully my wiring plan i never designed it to be universally understood hopefully it still can make sense to you, im a wiring virgin.  1 thing i have just noticed the pressure sensor in question relays both pressure and temperature, the temperature reading holds nice and steady despite the low ecu voltage but the pressure reading is the one that jumps around alot so maybe it is really a pressure issue? wiring plan.xlsx
