Cold air induction with an intercooler would have little effect on piston temperature.  Water induction, on the other hand, WOULD lower combustion temperatures, but, I can't help but think it would be to the detriment of performance.  These iron-head diesels like it hot, hot, HOT!

Thank you for you help really it's hard to get help out here in the middle of nowhere i'll try this.
What do you think about cooling this engine with out oil injectors could water injection or cold air induction with inter cooler work?

RE: [diesel_mercedes] Re: Doing some R&D need your help

 

I earlier wrote on this topic that a one-time poster here, and acknowledged MB diesel guru, known as "Stretch", installed a turbo on a four-cylinder 240D.  Indeed, one of the things he did was to machine the holes in the block to drop in the piston cooler jets.  He did that because none of the four-cylinder cars ever had a turbo, and so neither the piston coolers, and he wanted to prove a 240D could be turbocharged without sacrificing reliability, if done correctly.  I doubt he would ever have considered installing piston cooler jets into a normally aspirated five-cylinder block in order to turbo it; there're just too many turbo-engines out there for cheap that are already properly set up.

But, to answer your question:  Yes, the normally aspirated and turbo blocks have the same crankshaft journals and oiling passages, but for the piston cooling jet holes.  In fact, the journals are even shared with the 240D....

So, what's wrong with this parts engine?

The 300D engine I have would it have the same oil journals board in it as the turbo engine I have found good parts so far I have a great running engine just trying to see if I can work with what I got, or keep up the R&D I have found a parts engine I can get all the stuff I may need to turbo this running car, well good luck with your projects.
