Turbo advice OM612 G-Class
Turbo advice OM612 G-Class
I had a software modification on my G last year. the performance and torque was better but I got big problems with high water temperature, charge air temperature and oil temperature. After that the engine said goodbye so I tested where the weaknesses of the engine are.
First of all: I do not want to install another engine and do not yet convert to cp3 or c30 injectors because I want to test step by step where problems again arise. And the prices for C30 donnor too expensive for mileage over 300 thousand kimoleters.
Now I have rebuilt another engine and changed a lot about it.
Data Mercedes E Class om 612 with 170 ps (original)
Intercooler converted from water-air to air -air 3 times bigger!
Oil cooler converted from water oil to air oil
Exhaust system 3 inches.
Swirl flaps expanded.
EGR deactivated and locked.
4bar map sensor.
Now it's about the turbocharger: My question to you:
I want to have about 230 HP (Stock170) on the engine and 600 MN (Stock 400), but the whole thing should respond quickly and is an off-road vehicle that is used for pulling trailers, so it also runs for long periods under full load. So it is wise to have a Gt2259 with billet compressor wheel built because I have an original GT2256V and I also have a broken GT2359V from OM613 here and saw that it is possible to assemble it.
Is the exhaust side of the GT22 too small or do I get too much back pressure with my expected performance?
Is the GT2359V too sluggish in the response behavior in the plug an play solution without c30 and CP3?
