Re: Mercedes Deisel --->Turbo Install *LOOK*
black smoke in deisels means lots of fuel. you can take stock deisel trucks, chip the ecu, dump a ---- ton more than stock fuel in the cylinders, and get instant horsepower. so i don't see why when it smokes you can't just turn up the boost to get rid of the smoke, cause then the gas to air ratio would even out more, and you would see more hp i suppose.

Re: Mercedes Deisel --->Turbo Install *LOOK*
As a Mercedes Diesel owner I can give you some hints on tuning this diesel. Basically to tune a diesel you turn up the fuel until it starts smoking then back it off a bit. Your key to power is how much air your engine ingests. With more air you can burn more fuel. The more excess air you have in the cylinder, the more power you extract from the fuel you burn. Excess air also keeps the EGTs down. If you are going to turn up the fuel you'll want to install a pyrometer to monitor your EGTs so you can keep it below 1200 degrees F.
I do want to warn you that non turbo Mercedes diesel engines are different than the turbo engines. The turbo engines have oil jets that squirt on the under side of the pistons to keep them cool. There are some other minor differences as well. The general consensus of Mercedes owners on turboing a N/A diesel is don't do it. This is mainly because they take very good care of their cars don't want to blow up their engines. Another reason is you can get a million miles out of a Mercedes diesel and they view all other Mercedes like theirs as a potential organ donor and don't want others to blow up their engines as well. Its your engine burn it up if you want, it would be better to get a turbo engine to drop in.

Around 1220 °F pure aluminum starts to melt. Stock the EGTs of my turbocharged 300SD can exceed 1050 °F. These EGTs are of the gases after they have expanded and lost heat to the block. Before that when they are compressed at 21 to 1 they are a lot hotter.
Oil jets to cool the pistons isn't the only thing that differentiates the Mercedes turbo diesel engines from their normally aspirated counter parts. The pistons themselves differ to allow the oil to cool them better. They also have to have sodium filled exhaust valves to keep the valves from burning. There are other differences too but these three are the main ones that will keep your engine from melting down.
One final important difference is injector pump has a gizmo (The ALDA) on it that adjusts the fuel injected based on current boost level.
Yes you can convert your engine to a turbo engine but really its just easier to get a turbo engine and drop it in.

So, forgetting about how much horsepwer i would gain how much boost could i run safely, if any? what if i put in an oil cooler would that help? and a huge front mount intercooler? I hear of people converting deisels to turbo all the time and also heard that they are easy to do and can handle the power, so it is surprising me that this is an issue. why is it that you can convert gasoline engines to turbo with little to no problems? also, would i need different glow plugs for turbo setup? thanks

Re: Mercedes Deisel --->Turbo Install *LOOK*
Ok I have a general diesel question, why would a turbo diesel not be building boost. I have made sure that everything is sealed and even have a new wastegate but only vac, also i have checked the turbo and it seems to be brand new looking spins free. Could it be that it has old injectors that arn't puting out a good amount of fuel?

HMT doesn't care much for naysayers, where there's a will, there's a way. Diesels are rock solid, you'll kill the engine, but probably not before you kill the car its in.
Oh, common rail diesel engines work at fuel pressures of between 1000-2000 BAR, its enough to cut through several inch's of concrete.
