I dont think they are...i hardly use mine even though its installed

Someone reputable here once said its not necessary because of something or another, i forgot sorry.

If anything, you can always turbo time ur car yourself

However, the only time i can see where it is necessary is when u really need to get out of the car in a hurry and cannot wait around for the car.

best benefit i get out of having a turbo timer is when i turn my car of and start to walk away and some one says "hey your car is still running"

and then you say "nuh its ok it turns its self off" makes me feel special when i say it :P

that someone reputable was sydneykid

n the basic gist of it was that theyre worthless coz

1. the car sitting still wont cool the oil, moving air cools it. so driving around the block before u turn the car off is more effective

2. they make the car easier to steal

haha 2nd that

It says something about leaving the car to cool down if car has been driven under load or above 100km/h in the car manual, thats the only reason i got one. Tried without but after a few weeks of sitting there waiting for a minute or 2 it gets a bit annoying.

Another thing is i heard turbo timers void your factory warranty, is that true.

'third' that sam. get that 60% of the time at uni and work

Think about it...Nissan have put so much money into R&D into their vehicles...did any of them come with a turbo timer from factory?

That's why Nissan state in the manual to idle car if car has been under load (turbo squirts) for a minute or so. But if you don't do this, well you can just fork out for new NISSAN bits, which they are more than happy to supply you with. :P

Think about it, turbo timers must have a legit purpose. Otherwise there wouldn't be so many reputable brands manufacturing them, and people buying them the world over.

dat is indeed true hahaha had a guy follow me into woodvale shops kept sayin ma car was still runnin left ma jkeys inside ns tuff said it was alright n he goes i'm not liein go have a look ahha had to explain to the guy:P

I have one of the Apexi turbo timers and it displays battery voltage as well as a few other things which I've found useful. You can also turn off the unit which will switch off the car (if the keys aren't in the ignition) without having to wait for the timer to count down if you can't be bothered waiting.

They were first made to prevent older oils from burning up in the oil lines in journal bearing turbos. You don't have to worry about this these days as the semi and full synthetic oils are more resistant to losing their lubricating properties in extreme temperatures.

It's still a good habit to let your car idle for 30 seconds anyway.

With water cooled turbos the turbo never reached the coaking level that does the damage, so I would imagine the are a bit more nessesary after a turbo upgrade when things get hotter!

I have mentioned this elsewhere, but here goes again....

Standard turbos have a pressure fed plain bush bearing. When you stop driving the turbo can take a while to slow down and if you pull into the driveway and cut the ignition, the turbo will continue to spin for a short time, albeit without any oil pressure. If you have been sensible and driven nicely for the last few minutes, and you have a good quality oil in the car, no biggie, the oil present in the turbo will protect the bearing until it stops spinning.

If the oil is old / crappy grade and/or you have been fanging it home (or anywhere) and you shut off straight away either the oil in the bearing will drain away leaving the bearing to cop a hiding as long as the turbine is spinning, or the oil will stay in the bearing and get cooked, stuffing the engine oil AND your turbo!

I gotta say, I am getting pretty sick of hearing about how turbo timers let the turbo "cool down". Nothing will cool down by letting your car continue to idle.

They will, however, extend the life of your turbo when used properly. I just stay right off boost for the last 3-5 minutes of every drive and use a 30 sec timer on the TT. This makes it a lot easier when getting fuel etc as you don't end up standing around waiting for the car to shut off before you can refuel.

its not meant to cool the oil. its so the oil can keep flowing into the turbo to cool it and preserve the it, hence why cop cordias and vls used to blow there motors cuz they chase ppl, switch them off and 'POP'

i reckon there worth it saves hanging around.

im a trimmer and we deal with a few ssangyong turbo diesels which have the merc engine and they have a sticker on the driver door saying to cool the engine at idle before switching off, if the manufacturer reckons so id say there a good thing to have. they wouldnt make turbo timers for the hell of it, also my girls old car the mighty nissan langley had a timer standard which you couldnt 'switch' off

    • Thanks for that, I'll check it all out. I can always do the brakes last anyway if its a problem.  The 16's are super cool, if they do fit I'll cruise around with them for a bit.  
    • Well, that's kinda the point. The calipers might interfere with the inside of the barrels 16" rims are only about 14" inside the barrels, which is ~350mm, and 334mm rotors only leave about 8mm outboard for the caliper before you get to 350, And.... that;s not gunna be enough. If the rims have a larger ID than that, you might sneak it in. I'd be putting a measuring stick inside the wheel and eyeballing the extra required for the caliper outboard of the rotor before committing to bolting it all on.
    • OK, so again it has been a bit of a break but it was around researching what had been done since I didn't have access to Neil's records and not everything is obvious without pulling stuff apart. Happily the guy who assembled the engine had kept reasonable records, so we now know the final spec is: Bottom end: Standard block and crank Ross 86.5mm forgies, 9:1 compression Spool forged rods Standard main bolts Oil pump Spool billet gears in standard housing Aeroflow extended and baffled sump Head Freshly rebuilt standard head with new 80lb valve springs Mild porting/port match Head oil feed restrictor VCT disabled Tighe 805C reground cams (255 duration, 8.93 lift)  Adjustable cam gears on inlet/exhaust Standard head bolts, gasket not confirmed but assumed MLS External 555cc Nismo injectors Z32 AFM Bosch 023 Intank fuel pump Garret 2871 (factory housings and manifold) Hypertune FFP plenum with standard throttle   Time to book in a trip to Unigroup
    • I forgot about my shiny new plates!
    • Well, apparently they do fit, however this wont be a problem if not because the car will be stationary while i do the suspension work. I was just going to use the 16's to roll the old girl around if I needed to. I just need to get the E90 back on the road first. Yes! I'm a believer! 🙌 So, I contacted them because the site kinda sucks and I was really confused about what I'd need. They put together a package for me and because I was spraying all the seat surfaces and not doing spot fixes I decided not to send them a headrest to colour match, I just used their colour on file (and it was spot on).  I got some heavy duty cleaner, 1L of colour, a small bottle of dye hardener and a small bottle of the dye top coat. I also got a spray gun as I needed a larger nozzle than the gun I had and it was only $40 extra. From memory the total was ~$450 ish. Its not cheap but the result is awesome. They did add repair bits and pieces to the quote originally and the cost came down significantly when I said I didn't need any repair products. I did it over a weekend. The only issues I had were my own; I forgot to mix the hardener into the dye two coats but I had enough dye for 2 more coats with the hardener. I also just used up all the dye because why not and i rushed the last coat which gave me some runs. Thankfully the runs are under the headrests. The gun pattern wasn't great, very round and would have been better if it was a line. It made it a little tricky to get consistent coverage and I think having done the extra coats probably helped conceal any coverage issues. I contacted them again a few months later so I could get our X5 done (who the f**k thought white leather was a good idea for a family car?!) and they said they had some training to do in Sydney and I could get a reduced rate on the leather fix in the X5 if I let them demo their product on our car. So I agreed. When I took Bec in the E39 to pick it up, I showed them the job I'd done in my car and they were all (students included) really impressed. Note that they said the runs I created could be fixed easily at the time with a brush or an air compressor gun. So, now with the two cars done I can absolutely recommend Colourlock.  I'll take pics of both interiors and create a new thread.
