Interesting. I spoke to my local dealer a couple of months ago and was told 5w 30 semi synthetic was what they used at the time.
Thats on a 03 STi.

In the end of the day, if nobody is sure...use whatever it recommends in the owners manual - it's much more reliable and accurate than a BBS

After a lot of thought having looked at the hundreds of threads on oil, I finally opted for Silkolene ProS 5W40 Fully Synthetic - which I got for a reasonable price direct from a supplier depot near Redruth. The official Subaru owners manual recommends 5W30 for a MY01 WRX.

I cannot believe that oil affects turbo spool, sorry, let me just check the calendar.
you might have done well to call respected tuning and service shops and ask what they use in their own cars, usually a give away
personally it been motul 300v 15w50 for about 18 months now.
I had been concerned about the cold starts in the depths of winter but never seen a negative temp yet so wont change just yet.
there was some experimenting on 22b (Tone?) between 15w50 and 10w40 as a few of us have noticed a little background noise on the engines (as in knock display on a commander, not the engines a little louder to hear), but I havent seen the results yet and can never be arsed to change brands as it suits my needs to a tee.

turbo spins at what? up to 120,000 rpm at full chat?
and your telling me that using 15w50 slows this down a bit, noticeably in fact.
Engine works at what? say 8.2k rpm maximum for an sti?
if a unit weighing next to nothing spinning at 15 x engine speed cant "cut" through thick oil then jeeeez, I'd hate to think how much effect its having slowing down my engine, maybe with 10w40 I can get round the rev range a lot quicker and have no need to do any more mods.

will your turbo spool quicker in thicker oil ?

turbo lag is crudely/roughly the time it takes to fill the pipework and intercooler with air before it reaches the engine, in a roundabout sort of way isnt it?
ie not based on oil whatsoever
