My mate owns one and he has put a boost gauge in the car and because we have no manual for the car we can't figure out what is wrong, i think it's that he hasn't disconnected the old guage however he informs me that it is electronic (meaning that there is a pressure sensor inside the pipe) not mechanical. I was wondering if anyone can back this up as i don't wanna pull it off then have to put it back on.

I know it's not working properly as the original is in mmHg and this in psi and I've work the calculations out and his new guage is showning 5 to 6 psi when it should be showning 10psi.

Any help or advice would be great

ok well if your running a boost line into the cab i beleive the best place to take it from was underneath the top mount intercooler.

there is a rubber line that goes to a metal part and then out rubber again under the cooler. you can t peice it there and if all goes well it should be sweet.

other than that thats all i can say given the limited info..

and thats how i threw a mech guage on mine while testing it out.

but and a big but here.. be sure to have all the lines around that area firmly put back on. as when you undo any line around there and its leaking your running max boost.. it sure is fun but the poor little fuel pump cant keep up..

hope that helps you out..

i am a wee bit drunk but thats how i had it on my r back in the day

i would use neither. the line mashrock suggested is the pressure feed for the wastegate actuator, so if something goes wrong you will get unlimited boost. the fuel reg line i wouldnt touch either, as it's the pressure feed for the fuel reg. and if it stuffs up, no fuel pressure above the base 38psi.

find the map sensor. it's a little black box bolted to he inner guard. it has a vac line and and elec line going to it. that is the sensor for the stock gauge. tee into the vac line going to that. best way to do it.

      Not R7R. Meant to type R&R, obviously enough.

      R33 headlight relay conversion?

      By GTSBoy · Posted

      Bugger "making it look stock". I put one conventional internally fused Hella relay behind each globe. I just pulled the plugs off the back of the globes and built new loom segments with male and female plug parts to match up to the original loom and the globe, and used the original power wires to each globe coming from the switch through the original loom plug to trigger the relays. Ran a big fat (also separately fused) power wire across the front of the car to feed all the relays. It's as ugly as f**k, but it is wedged down between the headlight and battery on the RHS and the airbox and headlight on the LHS, and no-one ever looks in my engine bay, and on the odd occasion that they do I simply give no f**ks for what they think. Fully reversible - not that you'd ever want to. For f**k's sake. It's a Skyline. They made million of the bloody things. We've been crashing them into roadside furniture for 30 years now. There is a negative side effect to putting relays on the headlights. The coil current is too little to properly clean the contacts in the switches and they get blacked up and you have to open them up every couple of years and clean them manually. I have 25 years of experience on this point.

      R33 headlight relay conversion?

      By joshuaho96 · Posted

      I was poking through the R34 wiring diagrams vs R33 and noticed that the R34 has proper headlight relays while the R33 is like the R32 and sends full headlight power through the headlight switch. I'm not afraid of wiring but I really would like to do this in a way that looks OEM (clipping into open positions on the OEM relay box) and also unlike the factory wiring which interlocks the high beam and low beam on the halogen series 1 GTR headlights I want to make it such that turning on the high beams keeps the low beams on as well. Any advice on how to locate the specific connectors + crimp terminals + relays I need? I was thinking one NO relay for low beams and another for combined high + low running off the factory high beam headlight connector. I don't really want to splice into a crusty old probably discontinued factory harness so fully reversible is my goal here.

      Pretty sure they run the same engine as the Q50 hybrid which specifies 95 RON.  I ran 98 in mine for a while, but it made no difference in performance or economy, so I have been using 95 for the last few years.  I have never hit 6.0L/100km, but have returned mid to high 6 on the highway.  Being a hybrid, fuel economy is a lot more dependant on how you drive it.  At 110km/h, mine never goes into EV mode on the highway, so returns closer to 7.5L/100. urban driving can return low 8s if you are careful or over 10 if you are a bit more enthusiastic on the throttle.

      About a quarter of what you want to do. It's only R7R, not R&dismantle&replaceparts&reassemble&R. ? It is stock. I already told you, you will NOT have broken those. It's f**king 4th gear for Christ's sake. You just chipped the teeth off.
