997 GT2/Turbo performance pistons and sleeves ...
where from?
I wonder if there is anyone with experience? I'm looking for pistons kit which is able to hold 1000PS for a while.
thanks.K

Tough to take your question seriously. At 1,000-ish horses you need more than just a piston/sleeve kit. This is the stuff of uber-specialized guys like Ruf and even they haven't quite reached your numbers yet (9ff?)
As an aside, how many guys do you think have had 1,000bhp upgrades done to their GT3s, and are able to share an informed opinion with you?

Ruf is far behind I know guy who developed 740PS engine for rt12s.
I need just pistons kit, all the rest I already have.
9ff use very low quality pistons, much lower quality than stock mahle.

if you have the budget, talk to these folk - http://www.schmid-motorsport.de/index.php
German tuners in general offer warranties on their work, once you start getting into the stratosphere, there isn't much info on warranty costs, so they don't offer tuning options that might grenade anytime.
One of my friends has a car similar to your requirements, its engine is rebuilt every year. The standard chassis needs a lot of work to handle the sort of horsepower you are talking about.
Incidentally, I've never had a turbo engined car that did not get its turbos replaced under warranty. There are any number of tuners who have experience of getting up to 1500 PS out of quite small motors, but they don't do that for long. With that much power you are always managing temperatures. Its hard to get enough air into the engine on a 911 without killing the top speed.... else you only do it for short periods.

I have very very bad experience with schmid I wouldn't give him my bicycle for painting and I'm not joking.
I'm surprised that you mentioned about him, he have no clue about tuning.

if you don't like Schmid, try TTP, he has experience of BMW F1 engines in the turbo days.
If you think that this much horsepower is not about managing temperature, then you will be in for a big surprise. Go and count the radiators on the Veyron, for example. All that horsepower ends up as heat, and not just from the manifolds, engine and turbos, the gearbox, differentials et al.
And then you need to ensure that you don't get a bad tank of fuel, most of the time when I've asked what has caused the turbo/manifold problem, I'm told its bad fuel.
Incidentally, I've been involved in a few high horsepower projects, and it ALWAYS comes down to air mass and temperature management. If you only want the car to last for a few days, then you can get away with it, but regularly running the car as fast as it will go for hours at a time (wish germany was bigger), then you have temperature problems.

If dealing with tuners, it helps if you get on with the guy who is doing the work, just poking money at them doesn't work.

my intake temp during maha dyno run is max 50c after 30sec full load, ambient 28C.
behind TTp is guy I know well,he is free lancer flying all around the world to the customers.
you are correct only with the fuel quality problem a specially here in poland, but aral 102 is fine.
notice my engine produce 800PS and it's running without any problem for some time now...

for specialist engine components, talk to Pankl

PS drive your car flat out one day from Berlin to Wettstetten and arrange for MTM to put it on their dyno as soon as you arrive, you will be surprised how many PS you lose through heat saturation. You should do the trip in well under 2 hours. Then carry on down into Italy, by the time you get to Rome your car will have no more PS than a stock Turbo. The car will be well past its saturation point.
