Hello,
what is the max. boost pressure for a EA82T engine till his headgasket blows, i mean only the engine, not the turbocharger.

Depend on what other mods you have.
If its a stock standard EA82T, i wouldn't go over 9psi
If you have an intercooler, larger exhaust, run premium fuel, you might get away with 12-15psi
Just remember that the higher you push it, the higher the chance you will blow it up

im looking forward to mount an intercooler
do you mean the larger exhaust after the turbocharger or befor? because i think after the turbo, the exhaust is a little bit to small.
I run fuel with 98 ROZ

I doubt you would blow a head gasket, that comes mainly from overheating.
But its possible you could blow a ring landing off.
This is a good read that Disco started over at USMB, it has lots of input from people (me included) that have upped the boost on the EA82T.

hope it's big enough
I hope i will eliminate the overheating by mounting a second radiator-ventilator

in another forum some guys said to me i have to watch out for the engine characteristic map by using another turbocharger with more boost pressure, is that right? and how can i change the characteristic map? i know it isn't easy but is it needed by an EA82T engine?

ooh...
Reminded me of this - its off from another EA82T when he boosted it up too high.
