Being a new R32 GTS-T owner (as well as it being my first turbo car). I have heard people talking about warming up & cooling down the turbo...

Being new to turbo cars, I just want to make shoure I am not going to stuff it up.

My R32 is stock (except exhust) and I was wondering about the do's & dont's with warming up & colling down with turbos. With a stock setup is it a big deal or is it when you have high performace parts on the car?

when you drive a turbo car hard under boost it gets extremly hot ie the whole rear part of the turbo glows red so you should let i cool down when you have thrashed it also driving it quitely for 2 mins before turning it off will suffice.

this is an idea of how hot they get disreguard the writing.

For the past ~2.5years of owning my 32 i've never really warmed it up or cooled it down.

Warming up.

It idles for the amount of time it takes for me to put on my seat belt, put the cd players face on & put my wallet in the glovebox.

I then drive it real easy until it is at operating temp. I then drive it normally until ~10km's later from initial startup. It takes around 1-2km's to reach operating temp.

Only after then do I give it some stick if I am going to.

Cooling down.

I havn't got a turbo timer and don't really see the need for one, especially when you consider the possible insurance and defect hassles.

Before you turn the car off just take it easy for the last few km's.

Then let it idle for the amount of time it takes to grab your wallet, take the seat belt off etc.

If I have really been giving it a heap (can smell the brakes etc still) I let it idle for 2 or so mins.

General driving with the odd little bit of stick I don't worry about cooling the car down, just make sure turning the car off is the last thing you do. This will give time for the turbo to spool down.

Only once I have turned the car off just after coming off boost. The nasty sound of the turbo spinning was enough for me to instantly start the car and wait a minute or so.

It seems the ol' turbo's being water cooled and oil cooled are quite tough items these days. I've been pumping quite a bit of boost through it for some time and it still hasn't broke. :) I don't race or give the car a hard time or do high speed high boost long stints.

Out of all my cars this 32 has been THE most reliable out of them all.

Driveline, diff, motor everything is tough, and thats comparing it to a VS V8 5speed that are 'supposed' to have tough gearbox's. Mine still broke within 6months, then the diff then the rear subframe and the list goes on. :D

I've got a $0 bodgy way to increase boost if your interested.

You have to be carefull though. :)

Elongate the wastegate actuator bracket bolt up holes. Then pull the wastegate actuator and bracket back tightening it up. (Pull the wastegate actuator towards the front of the engine) Then tighten up the two bolts.

You then need to take it for a drive and fine tune the adjustment so it doesn't over boost.

Thanks for the info, it has help to clear some things up for me.

Since I dont drive it hard (all that much) there isnt much i need to do. Except make shoure it has warmed up before driving it hard, andif I have been riving it hard to take it easy before I pull in the driveway.

Thanks again.

      Actually, that's not entirely true. It's also the same motor in the 1st gen Nissan Cube but they're rare as hen's teeth.

      Unknown sound similar to BOV on positive boost with partial throttle RB26

      Yeah it is always worth testing and balancing actuators out of the box, just set the pressure regulator on a compressor very low (eg 5 psi) and increase it slowly to see when they both move.....unfortunately while you may be able to adjust the length of the actuator rod to minimise any difference, the actual pressure they move from is not adjustable so you need a well matched pair. And yes, the VCAM is probably contributing; the earlier in the rev range they come on boost and the slower the revs build (I think your demo was in 5th), the more you notice it.  Driving at WOT through 1st, 2nd, 3rd etc you will probably never hear it as any shuffling starts and is over super quickly

      oh they were with that motor, you need to remove the engine to change the spark plugs (don't have to, but it does make it easier)

      I certainly fall into the annoyed camp, but glad to hear that if it's happening at low boost then I'm not likely going to blow a turbo and end up with metal shards in my oil. Just feels like it prevents me from really driving it without hesitation and "peak" performance. Wonder if it's the VCAM, it did an impressive job of shifting the torque curve and faster spool, but maybe now it's "too fast" and there's too much air for how open the throttle is.  Based on some other threads, will also do some reading on synchronizing the actuators. They are the default actuators that come on the Garrett's and I would think they would be set the same coming from the factory, but if the turbos don't actually work exactly the same way at the same time as previously mentioned, it would be worth making sure the actuators are actuating together properly

      I went down this rabbit hole before, ended up sourcing a motor from the UK (I'm in Japan) which also didn't function correctly. With the original motor, I disassembled it and reassembled it and it works somewhat, sometimes. What I could deduce from all my screwing around is that there is calibration of the gears on the inside of the motor and two ramps on the main gear which activate switches that operate the motor and move the sunroof either to retract into the roof or tilt. Where I got stuck was that, it seemed in my case that one or both of the switches that are activated by the ramp on the gear did not always activate and thus the motor did not move, causing it to sometimes not retract or tilt (apologies, I've forgotten which way it didn't work.).  Of course this part is discontinued at Nissan now, it's the same part in the S15 but no other models. I also contacted the manufacturer of the component for schematics - forgot the name, they're based in Gifu - but they declined to share the information due to being bound by an NDA, sadly. Looking through my pictures now, it seems I last had a crack at this in 2022. See, I so kindly wrote "open" and "close" next to the switches. If you figure it out, please do tell me. Those little switches, with the red buttons may need to be replaced.
