Hi just bought my first skyline it's a n/a r33 I have noticed a couple of small faults but one thing that seems to be odd and bugging me is when I go to warm the car up and I turn the steering wheel the revs seem to jump abit not by much maybe 200-300 rpms not sure what seems to be the problem doesn't affect the driving really but just curious to know what seems to be the cause . I'm also curious about the 2 lights I have on my dash one says "SLIP" and the other "4WD" I have seen other r33s with this but not sure what they mean or when the light actually comes on . Anyone know anything about these things and could let me know ? Thanks :)

The revs jump when you turn the wheel because the power steering runs off the engine and the engine revs itself the stop it stalling. Same goes for air-con.

I'm guessing "SLIP" means loss of traction? "4WD" means 4 Wheel Drive. You must have a GTS4.

Edited by H4x

slip light means the rear wheels are loosing/lost traction, and when it stays on it means the front wheels are pulling the car. 4wd light means there is something wrong with the 4wd system, from my understanding

I believe your right about the 4wd light cause I removed the 4wd relay from the boot and the light turned on and stayed on . So does that mean the gts4 are only 4wd when the rear wheels lose traction ? Do you also know anything about it being 4 wheel steering ?

Cheers

if no hicas then no 4 wheel steering

Yes I do see hicas in the relay box , so from what you read is it safe to say I have a GTS4 ?

Just for future reference what is it that makes a gts4 ? Is it the 4wd ? Or the 4ws ? Or both ? =/

And my final question is does anyone Have any information about the LSD, it's an import too if that helps ? Cause there is a relay saying 4wd LSD is it safe to take this out and drive ? Will it even make it rwd ?

The revving up whilst turning is normal, as explained above. But the thing is, to hear it or for the engine to do that whilst turning, you must be stationary. You should never turn the wheel of a car while it isn't moving, if you're an OK driver, there's no need to. It puts undue stress on the steering components, specifically the PS pump.

from what i can remember most came fitted with hicas (there should be a light on your dash, a big metallic unit sitting in front of the rear diff)

as far i as i can remember the gts4 was awd (based on the whole gtr attessa system) 4 wheel steering (hicas / super hicas in some cars) is just a factory option although most came fitted anyway.

& the lsd transfers power to the wheel(s) that aren't gripping when there is a loss of traction... in retrospect - drifters lock their diff so its the same amount of power to both wheels irrespective of traction - thus makes it easier to keep the rears spinning when drifting / linking corners..

GTS4 comes with ATTESSA AWD out of the GT-R; all GTS4 have the AWD, otherwise it'd just be a GTS.

Most Skylines have HICAS (4 Wheel Steer), pretty sure was standard on all but the most povo-spec ones.

the revs seem to jump abit not by much maybe 200-300 rpms

If it's sort of jumping from idle by 2-300rpm when you lock the wheel either side, as others have said it's nothing to worry about, but have a look under your car & check the condition of the usual suspension stuff like end links, ball joints & rubber cv boots etc

All cars with belt driven power steering have a power steering pressure switch with sends a message to a AAC valve which idles the engine up to stop it from stalling with the load created on the crankshaft.

Your car is a GTS-4 simply look in your engine bay at the fire wall and if the engraving is ENR33 (6 numbers) then thats a GTS-4. Slip light is simply loss of traction, the system is RWD and depending on how much slip the computer reads from a lot of sensors about 100 times a second it will send power to the wheels anywhere from 0-50% to the front.

All GTS-4's that are R33 and R34 NEVER came with HICAS (4 wheel steer) from Nissan because they are non-turbos and with the 4WD parts in the car making excess weight they did not follow in fitting it. The GTS comes with it because its RWD and 60kg lighter. I wouldnt worry about HICAS though, everyone sees the light sooner or later and just locks the 4 wheel steer.

    • Hi, is the HKS  Tower Bar still available ? negotiable ? 🤔
    • From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
    • Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.      
    • Onto the android unit. You need to remove the top screen because there is a daughterboard to put inside the case. Each side vent pops out from clips; start at the bottom and carefully remove upwards (use a trim remover tool to avoid breaking anything). Then the lower screen and controls come out, 4 screws, a couple of clips (including 3 flimsy ones at the top) and 3 plugs on the rear. Then the upper screen, 4 screws and a bunch of plugs and she is out. From there, remove the mounting brackets (2 screws each), 4 screws on the rear, 2 screws top and bottom and 3 screws holding in the small plates on each side. When you remove the back cover (tight fit), watch out for the power cable for the fan, I removed it so I could put the back aside. The mainboard is held in by 1 screw in the middle, 1 aerial at the top and 3 ribbon cables. If you've ever done any laptop stuff the ribbon cables are OK to work with, just pop up the retainer and they slide out. If you are not familiar just grab a 12 year old from an iphone factory, they will know how it works The case should now look like this:
    • Switching the console was tricky. First there were 6 screws to remove, and also the little adapter loom and its screws had to come out. Also don't forget to remove the 2 screws holding the central locking receiver. Then there are 4 clips on either side....these were very tight in this case and needed careful persuading with a long flat screw driver....some force required but not enough to break them...this was probably the fiddliest part of the whole job. In my case I needed both the wiring loom and the central locking receiver module to swap across to the new one. That was it for the console, so "assembly is the reverse of disassembly"
