What is the best way to warm up skylines? May seem like a silly question but the reason I ask is this.

With many German cars like BMW the manufacturers recommend to turn the car on, let it idle for a minute and then drive it nice and easy till it reaches the operating temp. This way the motor and gearbox warm up together.

Is this the best course to follow with a skyline or is it better to let it idle till it warms up enough and then drive?

I think I answered my self by posting this thread but would like to see what people think.

Letting the oil circulate is all that's required > then drive.

Letting the engine oil warm up is all that's required > then boost.

Letting the tyres warm up > then traction :P

Did you know that when you could hire V8 statesmans (many years ago) on a cold start you could apparently hit the rev limiter before the oil light went out? A friend told me.

To answer OP question, don't waste time sitting in the driveway idling. Cars these days (ie for the last 30 years) are designed to drive off as soon as you start them and build up oil pressure. Drive slowly / lightly until it's warm then go nuts.

learnt this with my 32,
had rough valve stem seals and warming it up on the driveway made it smoke worse

makes sence after thinking about it.

however my mate swears by starting it and after 10 seconds revving 1500 rpm constantly bliping it to 1500rpm.

recons it squirts oil up the engine. not sure but meh maby

For those 10 seconds or less.......... I'm free!!!!

what about warming up built/race cars?

my clutch and gearbox need to warm up before its driveable basically.

and the oil pressure is high and all over the place until its warmed up. So usually start it and either dab the throttle for a bit and leave it for 5-10mins just idling.

With a race car with a crappy tune and animal clutch you don't have much of a choice. I had a group N Daihatsu charade rally car like that once. Yes, despite only 57kW at the wheels it was a pig to drive when cold (stuck with using factory sensors on a very old F7 Haltech, and a bitey 3 puck clutch). Once it was warm it drove like the (underpowered) shopping trolley it was.

I was happy to sell that gutless POS.

Still, if you can drive the car without having to warm it up first, then that's always your best bet.

Don't know about others but when i start my r34 gtt i leave it to warm up until the needle temperature reached it's normal stance which is halfway as it takes

at least 6 minutes but thats just me.

Problem with that, as mentioned above - the oil pressure is at its minimum while its idling, and the ECU is adding more fuel to get it up to temp quicker.

Your way better just driving easily for the first 10 minutes and letting everything warm up together.

In the GTT you've got the advantage of an oil temp gauge - halfway on the coolant Temp needle could be anything. 10 minutes of light driving see's my oil temp stable at 80* and then its ready for whatever

Driveway ildling is pretty pointless, much like idling for minutes after you've stopped to cool your water cooled and oil fed turbo :)

the cold start tune is fine. I'm only following the clutch instructions letting it warm up before driving and stabilise oil pressure.

Thats mental dude.

I don't think we should be looking to you for engine advice, based on your not revving over 3200 rev thread.

    • I thought I'd do a write up on an auto transmission fluid change for a the nissan 7 speed Automatic. At some stage the genius engineers decided that the fluid in the trans was "for the life of the transmission", (which seems kind of self supporting to me) and removed the dip stick and fill tube (funnily enough there is still a casting for it). Anyway, for this job you do need 2 specialist tools in addition to regular hand tools, jack and good chassis stands. You need a way to pump fluid up to the transmission; I got one of these but there are plenty of other options: https://www.ebay.com.au/itm/364584087070 Don't trust the generic listing though, it does not come with the required adapter for the Nissan 7 Speed. You need one of these, can't do the job without it: https://navarapart.com.au/product/genuine-nissan-patrol-y62-d23-np300-navara-re7-dipstick-fill-connector1 You need a heap of compatible transmission oil. Could be Nissan, could be anything else rated for Nissan Matic S. You need at least 10 litres, I had 15 to give it a better flush... Also, you need some biiig oil catch trays, at least one of these, or bigger if possible (volume was fine, size was very marginal): https://autobarn.com.au/ab/Autobarn-Category/Tools-%26-Garage/Specialty-Tools/Oil-Service/Garage-Tough-Oil-Drain-Pan-Black-16L---GT1068/p/TO03191 Finally, a measuring jug is very useful if your pump does not have volumes marked on it, I got a 6l one: https://www.repco.com.au/oils-fluids/fluid-accessories/measuring-jugs/penrite-measuring-jug-6l-pmj006/p/A5322648 Oh, and gloves.....this stuff is horrible (not as bad as diff oil, but getting there) ....First, jack up your car.....
    • So I mentioned the apprentice, @LachyK helped take the bonnet off. We just undid the nuts on the hinges and unclipped the gas struts, then pulled the bonnet back a little as the front was catching on the front bar.  I had a good look at everything today and have removed the rams, repaired/reset the hinges and bolted it back together like it never happened. I'll do a separate write up on the repair, and I also removed the poppers from the Fuga today too to save grief down the road.....as said above it is at least $5k to repair retail. I'm also happier about my ability to prepare a race car, and less happy about Nis-nault's engineering (I can hear @GTSBoy sAfrican Americaning) because the top hose of the radiator didn't slip off.......it snapped clean off. By practice I put the hose clamp hard up against the flare on a neck to make it least likely to ever move (thanks @Neil!). I guess that puts a little more pressure on the end of the pipe as it is further away from the rad, but still, that is pretty shit. I've put it back on for now as there was a fair bit of neck still there, but obviously there is no lip on the neck any more so I don't think I'll track it again until I have a new rad. Speaking of which....more research required. It looks like Koyo makes a standard size radiator in ally which I'll grab in the meantime, but I really want something thicker so might have to go custom in the medium term (ouch) Coolant still needs a refill and I have the pressure tester on it over night, but other than a wash down of the engine bay it seems alright. And @MBS206 noted something noisy on the front of the engine and I think I agree....time for a new accessory belt and tensioners I think.
    • our good friends at nismo make a diff for it, I have one (and a spare housing to put the centre in) on the way. https://www.nismo.co.jp/products/web_catalogue/lsd/mechanical_lsd_v37.html AMS also make a helical one, but I prefer mechanical for track use in 2wd (I do run a quaife in the front, but not rear of the R32)
    • What are we supposed to be seeing in the photo of the steering angle sensor? The outer housing doesn't turn, right? All the action is on the inside. The real test here is whether or not your car has had the steering put back together by a butcher. When the steering is centred (and we're not caring about the wheel too much here, we're talking about the front wheels, parallel, facing front) then you should have an absolutely even number of turns from centre to left lock and centre to right lock. If there is any difference at all then perhaps the thing has been put back together wrongly, either the steering wheel put on one spline (or more!) off, and the alignment bodged to straighteb the wheel, or the opposite where something silly was done underneath and the wheel put back on crooked to compensate. Nut there isn't actually much evidence that you have such a problem anyway. It is something you can easily measure and test for to find out though. My money is still on the HICAS CU not driving the PS solenoid with the proper PWM signal required to lighten the load at lower speed. If it were me, I would be putting either a multimeter or oscilloscope onto the solenoid terminals and taking it for a drive, looking for the voltage to change. The PWM signal is 0v, 12V, 0V, 12v with ...obviously...modulated pulse width. You should see that as an average voltage somewhere between 0V and 12V, and it should vary with speed. An handheld oscilloscope would be the better tool for this, because they are definitely good enough but there's no telling if any cheap shit multimeter that people have lying around are good enough. You can also directly interfere with the solenoid. If you wire up a little voltage divider with variable resistor on it, and hook the PS solenoid direct to 12V through that, you can manually adjust the voltage to the solenoid and you should be able to make it go ligheter and heavier. If you cannot, then the problem is either the solenoid itself dead, or your description of the steering being "tight" (which I have just been assuming you mean "heavy") could be that you have a mechanical problem in the steering and there is heaps of resistance to movement.
    • Little update  I have shimmed the solenoid on the rack today following Keep it Reets video on YouTube. However my steering is still tight. I have this showing on Nisscan, my steering angle sensor was the closest to 0 degrees (I could get it to 0 degrees by small little tweaks, but the angle was way off centre? I can't figure this out for the life of me. I get no faults through Nisscan.
