dude.. this thread is soo full of win..
they make a bell adapter to bolt directly to my existing V6 trans?! and its from oregon?
i know what my next project is going to be!!
(i have a CHERRY 88 runner sitting with no engine, bought the audi 2.0TD for it, but i like the idea of a OM617 better..
Yes, right to the V6 trans. He said he's from some rural area of oregon, I didn't ask exactly where though. We chatted on the phone for a while and he seems like a solid guy.. I'll probably be ordering that adapter up very soon!
After driving the car around for the day, it actually seems like a pretty interesting engine. From reading forums etc, everyone was saying how quiet and lacking in torque it was. Well, when I started it up looking at it and when I took it for a drive, I was amazed at first of all how quiet it was and second how little torque it had! Put some music on and I would hardly believe it was a diesel.
When looking at it at first, I thought it might have low compression, mostly because the diesely clatter was very soft. But, it did well in aircare (smog), even cold start (0C/32F) there was just a very light haze of white smoke from the tailpipe and blowby was minimal. All signs of a healthy motor. Also it ran smooth. It doesn't buck or jerk at all, even at it's 600rpm idle.. just purrs like a happy young kitten
The power curve is interesting but I think half a fueling issue. From a dead stand still, I can stomp the go pedal. It hits the torque converter's stall rpm around 1400 and stays there for about 3 seconds slowly picking up speed, then once it pulls from 1800 up to 2200 it actually kicks pretty hard and pulls strong right up to 4000rpm where the tranny shifts at full throttle. It has an LDA equivalent on the pump and I think what's happening is there is very little fuel being put in off boost so it has trouble getting going, but once it does hit boost, fuel is dumped in and it gets moving. Turning off boost fuel up will definitely help with that, although I don't know by how much. I'm not going to touch the pump until I'm driving the truck with the Benz engine, so I won't know for a while.
One comforting thing is that I cannot get it to puff any black smoke. Oh how I tried... matting it to the floor from 600rpm and not a whisp which leads me to believe that fuelling is severely stunted to help keep the soot down. Which, as we all well know, means there are many more torques to be had!
That all said, I'm stoked. This seems like it'll be a great motor for my truck. It'll never have the brute monstrous torque of a 4bt but I'm not going wheeling anywhere crazy and I've got 4.56's and only planning to run 33's so gearing won't be terrible. Popping the hood, the engine bay is incredibly simple so I'll have no trouble figuring out what to delete and how to assemble it in the 4runner. It rev's just fine... it'll be happy as a clam winding at 3000rpm all day on the highway, idles smooth and should give some pretty good fuel economy! 150hp is easily attainable which will push a 4runner just fine.
I'm tired and need sleep. This'll start off slowly but the project will pick up momentum in a few weeks!
i would NOT run 4.56 gears.. they will be too low, and make the engine rev too high.
i always ran just the stock 4.10 gears with my V6 engine, and 33" mudders.. worked out soo nice.
Right now I'm at ~3000rpm for 110km/h which is just fine for the gasser... I'm never in much of a rush driving my 4runner anyway
33's would give me 2800 and 35's would give me 2650. Maybe I should just run 35's instead then?
Apparently the best gas mileage with the OM617's is around 2500 and lots of guys run them at 3000rpm on the highway anyway. I'll drive it with the 4.56's for a while anyway and see how it is

4.56 gears are NOT stock tho.. so unless someone swapped them in, or you swapped them, then you got 4.10s..
My 4.56 diffs are factory. All the 2nd gens that came stock with 31" tires and 5sp trannys came factory with 4.56's in them. I double checked my axle code somewhere as well and it came up with 4.56's
*edit - here's where I checked my axle code against

There is no replacement for displacement.
