1) From the time I turn on the car, to the time I start the 5m drive, how many seconds do I have?

do it as fast as you can but make sure you are turning the wheel enough....if it doesnt work try turning the wheel a little more....

2) In step 5, do I hold the brake in slightly and heel-toe it foward, or tap it in and out?

tap it in and out

I've put my car into diagnostic mode many times however last week when i tried to put a friends car into it i couldnt so just keep trying!

i got aftermarket wheels, hicas light comes on after 10-15 mins of driving over 80km/h, on freeway etc. If i turn the car off, and then on again it goes away. I tried getting it into diagnostic mode a few times, but with no luck.

Skyline 4ws only opreates when you are travelling and not stationary unless you are in diagnostic mode!

And yet it does. Perhaps the light is coming on because of it being unable to determine the speed of the car, and for that reason the wheels move... Who knows until I can get this diagnostics mode working.

Anyway, I'm going on the dawn cruise to the gong tomorrow, so I might be able to get some info on it there...

Go on laugh at me but im only trying to help :]

Well I'm even less of an electrician. But they're stock wheels and I don't think there's anything special about the tyres - they're still the ones the compliancer dude put on. Aside from an after-market stereo, I believe the speed alert chime has been disabled (unless I go deaf past 110kph :D) but that seems all... Who knows. :D

I think I'll try and get a knowledgable guy / girl to try and get the diagnostics mode working... :

My Hicas light comes on every time after about 10km, turn car off and go again for 10 and on it comes. Rang the guy who sold it to me who checked with a mechanic mate etc etc. Turns out I have an aftermarket diff - locker apparently, and this is what happens when you mess with the original diff.

Hicas on the R33 is fully electric. Topping up the power steer fluid won't do anything for you.

I never had a problem with my hicas and I had aftermarket 17" wheels on. I can't see how that could possible make a difference anyway, but it certainly didn't in my case.

My car was a R33 GTST

I have this problem too..

My problem is that the contact in the steering wheel isn't making contact so the car cant sense that the hicas is there.. or something.

It only happens when I go on the freeway and drive for extended periods of time without turning the wheel too much.

It just resets the computer when you turn it off so the sensors are working again. It was going to cost me $300 to get the part and more for the install. But I'm not too worried. It's not harming the car in anyway.

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      (it is a brand new ported mellings pump) I suspect the lack of pressure is due to the leak. It was *not* that low in other logs of oil pressure in the past. It wasn't that hot either, but not far off.

      Would a Mellings oil pump be a viable option  From my time with a LS, and talking to tuners and LS specialists, the "weak" OEM oil pump is one of the first things they recommend to swap out if I was going to give the engine any high RPM I opted for a Mellings high volume, with the high pressure springs and I never had a issue with it Cost wise they are not expensive in the scheme of things

      My new to me M35 Stagea wagon

      By davemoto63 · Posted

      Just bought a 2002 Stagea 250tRS VR-X Four AERO VQ25DET and spent the last two weekends cleaning and detailing it.. still have to do the wheels and the engine bay but the rest of it came up nice. Imported 2011 to S.A. and I'm the third owner since it was imported. I met the guy who brought it over, he went to Japan and picked out the car, bought it and ordered the wheels. He also gave me a list of stuff he did to the car with receipts. Coil overs (I have the original springs), 3" exhaust from the dump pipe back no cat, Custom dump pipe,(I have the original exhaust), Plenum spacer, 18" custom Work XSA wheels (need restoring, I've made a start..), Shift kit put through the 5 speed tiptronic auto, TV and menus/screens changed to english, Australian DTV tuner installed in rear. I've just had four new discs and new pads as well as all the fluids including the brake fluid replaced. I have all the receipts for the last 15 years and the import papers in a nice folder. Car looks great, goes like hell but fuel economy is not a thing lol.. pics next..

      Steps to DIY sanding car back ready for respray....

      By silviaz · Posted

      I ended up in this rut again lol, and used a shit ton of filler. One thing I can't understand is, even after using a big long block and going in long X pattern strokes, I always end up at bare metal again with no filler, and my repair started at one end of the door and now I've chased my tail to almost the other end of the door. I was thinking of hitting the panel with a hammer where it might be a high spot and making everything low then filling it, I did this on a small section on my other door by mistake and I think I fixed it lol. Is this a bad idea? The other thing is with guidecoat, whether it's the powder or spray, after I sand all the guide coat off, it doesn't reveal anything for me in terms of high spots and low spots and makes it especially hard when it's bare metal (at least in powdered form), am I doing something wrong here, or likely a high spot I keep going over and creating valleys? Lastly, stupid question but, is it possible that after sanding if I only sand over the filler area where I know to be a dent that it's impossible for me to dig into that dent? Unless there are other problems which I missed.
