Typical of MB diesel motors, suffix "A" is turbocharged. Suffix "LA" is intercooled too.Or maybe are the engine model always turbo or NA? (Ie: is OM353 always turbo...or are there both versions fir that (or any) engine)?
OM352 motor is 345 ci. OM366 is 346 ci.OM366A) use the OM352A which I also think is a 352 c.i. inline 6. Our truck has a OM366LA, so a 366 c.i. inline 6. I
Thanks Verkstad for the info. Since I am new to these trucks and have only seen ours I have no base for comparison. I do feel though that the OM366LA is a nice smooth engine and have been impressed by it. Just also found out that with an injector pump/injector upgrade I can get a bit more power out of the engine (up to 270hp). Also figured out our truck has the 39:8 ring/pinion so there is a possible upgrade to get a bit more top end speed with a swap. All it needs is a pile of money (which I am exactly one pile short right now ).OM352 motor is 345 ci. OM366 is 346 ci.
Substantial differences of design between them.
As much as I like charming oldschool 352s. Given me choice, 366 any day !!
Before you get too far, be sure your cooling system will handle that added horsepower.Just also found out that with an injector pump/injector upgrade I can get a bit more power out of the engine (up to 270hp).

Not sure about that, I know the American way is the decimal ratio (so 4.875). From the EPC and contact with a UK supplier MB does it this way. Guess this way describes the ring and pinion number of teeth (so 39 for the ring and 8 for the pinion)? It seems the American decimal way just describes the overall ratio. Once again, very green about this stuff and trying to learn along the way. I mean, this is not only my first medium duty truck but also my first 4WD (why start small?).Btw, 39:8 seems an odd way to express gear ratio. But maybe not if one cant use decimal numbers.
