Hello,

I am new to this forum and would like to get some information on the MB Turbo Diesel engines made from 1990 and up including reliability. What engines am I limited to?

I have a 1990 Toyota Landcruiser that has the 6 cyl. 3FE gas guzzler in it. I want to do a diesel conversion and use the automatic transmission in it or go to a GM 700R or similar. Due to the weight class of the Cummins and Isuzu engines are from the " medium duty class", technically they cannot be used as a legitimate engine for the "light duty" engine class of the Landcruiser. What MB Turbo Diesel engine from 1990 and up would be a possible candidate for this swap with a automatic behind it?

Thanks for any input!

Mark

Suggest you see the just published Mar-Apr 08 MB Star magazine and
read up on the soon to be introduced Mercedes diesel powered vehicles
and select one instead of doing a conversion of the Toyota.
Regards,

Mark,

Given enough time and money, anything is possible, so the answer is "Any engine you'd like!"

Seriously, you are going to have to fabricate:
Engine and transmission mounting
Exhaust
Air intake plumbing
Radiator mounting/plumbing

There are five cylinder and six cylinder turbo diesel engines (OM603 and OM602) that were used in the 124 series cars, all have some computer controls for emissions and transmission kick-down. Recommend you take a measuring tape to a junkyard that has a selection of donors and start by trying to figure out what will fit under the hood. I would imagine that you should use the center of the crankshaft as the baseline, as the crank has to align to transmission has to align to driveshaft has to align to differential, and measure from crank up to hood to compare with your truck.

Re: Toyota Landcruiser Diesel Conversion

The wife wants to keep the old cruiser as I do, but I just don't have the time to do the work on it. A new vehicle at this time is not in the budget. The cummins motor will require a minimum 4" of lift for the oil pan to clear the axle. Even though both the cummins and isuzu engines will fit and are viable options, they are not technically legal. Who knows what will happen in a couple of years with inspections? I think the MB is maybe one of the better choices.

Thanks for the replies.

Re: Toyota Landcruiser Diesel Conversion

Might be easiest to buy a Canadian market diesel landcruiser as a parts car and go from there. There seems to be some flow of RHD diesels from Japan to Canada. I'd think even sourcing the appropriate Toyota parts from Australia might be easier than changing engine brands.

Re: Toyota Landcruiser Diesel Conversion

How difficult is it to import and register a 89-90 FJ62 "diesel" into California?
