Marinising BMW 3.0 Turbo diesel

[marek916]

Sorry, I just presumed everyone was here as an enthusiast rather than a business...
That said, I would be happy to swap my designs & throttle PCB etc for an injector rebuild upgrade...

No worries.
I try to be both. I am an enthusiast and enjoy swapping ideas, but when it can impact on my business, I have to draw the line.
I would like to keep in contact, I am sure we can help each other out.

I'm not sure what the book figure for the engine is, I suspect it's around the 200hp mark but could be as low as 184 depending on ECU mapping.

Where the 315 race engines marinised BMW's or Yanmar specials?

To be honest I never checked which version it was, I assumed it was the ally one? - the dry weight of the motor is 315kg according to Yanmar?

The engines come as 260hp from Yanmar although I'm told well over 300hp is possible without any physical alterations.

The 315 Yanmars are from the old Landcruiser block and the new 370 common rail engine are from the new Landcruiser block.

My understanding is that the basic mechanics stay the same, but you need a different turbo, a remap and the larger injector nozzles to take it over 300 BHP. I have the bigger turbo and the nozzles, but have only mapped it for 275 BHP as the Castoldi wont take more.I am going to set it up on a dyno before installing it, so I know everything is working properly and will try some different maps whilst it is on the dyno.

Are you running single turbos on BananaShark?

Yanmar don't use the variable vane turbo from BMW, they use a single wastegated turbo for the marine version.

I think I have just found a rather simple solution to wiring these up....

I shall keep you posted on developments but its looking very favourable & easy plug & play stuff.

I have to say the OE wiring on these in a 530d is an utter nightmare & I'm used to dealing with car re wiring & engine transplants on a regular basis, these are the most complicated I have ever come across.
