What a joke. Thats the worst made intake manifold I have ever seen and that turbo is REALLY slow to spool.

Where is the flux capacitor?

Yes that's true NA OM617 won't handle normal (1bar) boost for long, only
way is to use OM617A that is turbo spec engine. It will handle boost up to 2bar with
no problems, but over 2.2bar is too much and the rods will bend. But changing the rods
for tougher ones it will handle boost up to 3bars. The block itself and the crank is very tough and will handle serious power.

question : is the block and the crank is the same in NA ant turbo 617 , or not ? as far as i know pistons are differrent. what i need that NA would hold the same power as turbo , but safely as much as possible ?

Yes and no, crank is the same, basic block is the same, turbo has oil squirts in the block and the lower block is different. Also turbo has bigger oil cooler, different pistons, better valves also camshaft is different.
Mine is basic OM617A.951 (600 000km) with modded head (both channels) and valves, little larger bore and everything new inside engine.
I think it's cheaper to acquire an turbo engine and build from that, than change an NA OM617 to handle the extra heat and load

Naah, it's only the wiring and connector betweeen temperature senros and gauge that is causing resistance difference. Problem has been there from the time i got the car and yes i measured the right temperature from the head and water to check that there is no overheating. This engine is not easy to get overheated (atleast in our climate :D).
