How do you get on with insurance with these fitted..? Do you declare I wonder, as I can't see them being very happy about it..?
As said, just take it easy the last mile/min or two, most people live in residential area's so unless you're one of these tools who drives like an idiot down these streets, then you'll should be taking it easy anyhow..!
Now if you lived in a m'way service....! (BTW how many of you think about this before stopping at a service station for fuel..?)
Finally, newage cars do 'percolate' (iirc) the coolant around the turbo after the engine is switched off, I still however, take it easy, mainly as I live in a residential area..

What about runs out in the countryside/moterway driving etc - I dont mean its to be used for poping to the shops
it just saves you time sitting about after a sudden stop to have a ****
and its great for warming your car up on a cold morning without worrying your car will get nicked

Why would Subaru fit something that has the possiblity of reducing profit. At anything from £700 to £1500 approx, for a new turbo upto £50 for a Turbo timer seems a good idea. Up here in the North of Scotland mine is also used first thing in the morning to warm the car up to allow it to de-ice or in summer to run the air-con to cool the car down.
I was told you should never start the car cold and leave it to warm up ???

I had one fitted to my little Ren 5 GT Turbo back in th late 80`s.
The amount of people who came running after me once I`d parked up, "Here mate you`ve left the engine running".
If I had a pound..............................

Also, presumably the engine will be under absolutely no load so not really a proper warm up..!
Therefore if you think you can idle the engine for 10 mins and then drive like you stole it you're in for a surprise before long..!
If however, it's just to warm the heater up in the winter before you get in then that's ok, if you must, but a waste of fuel if you ask me..

There's a couple of things here.
The time is not there to allow the turbo to slow down, they accelerate and decelerate very quickly.
They don't use a white metal bearing as in the bottom end, a sleeve bearing is a different thing using boundry lubrication rather than hydrodynamic. It won't wipe like a white metal one will. Some of the IHI turbos use roller bearings instead which is still no issue.
All the subaru turbos are auto cooling once stopped. For a modern synthetic oil to sludge you'd need to hit 200+ centegrade. If you did your coolant would boil and pop the pressure relief on the header tank. If that's happening every time you drive you're probably doing something wrong.
Just take it fairly easy on the car for a couple of mins before you park.
Take a look how many members are on here, then see how many blown turbo threads there are. Not many I bet.

Yes, the water constantly circulates. Natural convection does this while the engine is stopped so the hot spots are still being cooled via the water jacket once the you've shut down.
If that wasn't the case you'd get localised boiling in the water jacket.
