Ok guys, I looked all over the engine for numbers, all I could find was on the left hand side of the motor if you are looking at it from the back of the bus, it looks to be on the head though.

Here is that number... 5148642 below that is 68 and next to that is B.

The only number I could find on the turbo is... M11

I had dinner last night with my Ex boss at the city shop. He went to school back in the day for these Detroit two stroke's and worked on them up untill he retired. The first thing he asked me is if it had the bypass blower. He is going to come over and show me how to adjust everything including the Jakes. He thought we should try that first and see what happens. He wasn't real sure that it was going to gain me much, but worth the try and good experience for me.

I'll post back when done.

Just an update on the tune

I just got done taking the bus on a drive out of town and up the pass. The only noticeable difference was the Jakes when coming down the hill. Everything was pretty close as far as the adjustments go, except the Jakes. My old boss Don, he didn't think that changing the blower or the injectors was going to gain me a whole lot in the climbing department and he didn't think I would gain any MPG either. He said that he didn't really care for the early 8v92 like I have.

I went and bought my brothers series 60 just because it is a good deal and comes with the whole truck. Over the next year, I plan on collecting all the parts I need for the conversion a little at a time. I'm kicking around the idea of going with an auto shift. I just need to do some measuring and a whole lot of research to see what will gain me the best power and mpg.

Gary, I think you would like the AutoShift.  It is pretty slow on the acceleration (in my case, partly because I am pretty soft on the throttle for all of the gears until I get to 7th).  One of the issues is that you loose boost with each shift.  However, it is fantastic on the hills (big and small) as you always have the correct gear.

The Series 60 will need to be a DDEC III and maybe DDEC IV, and you will have to have DD or someone with the proper program activate the J1939 port.

I list the shallow pan parts on my project pages as well as my wiring harness.

If you go with the AutoShift, they call for two shielded twisted cables in the wire bundle.  The wire they call out is very expensive, but I can give you an alternative.  BTW, all of the AutoShift manuals are at roadranger.com.  The main manual you need is TRIG0050 and you can download it from here:

http://www.roadranger.com/Roadranger/servicesalesliterature/LiteratureCenterResults/index.htm?&pt=OW_GL_RR&target=1162919212424

If you post your Series 60 serial number, we can sort out what you have.

Jim, thanks for all that information! What kind of mileage do you get on average?

Clifford, how much difference is in the pans from the truck to the bus? How about $ ?
My bus has been lifted 3" for traveling Alaska roads. So I have a bunch of clearance under it right now.

Gary, the truck pan is quite deep and the sump would be in the rear of the bus (see photo - used in my article).

The pan and pickup from a DD dealer is about $1K.  I think they have about 4 versions, I chose the least costly.

What is so miraculous about that pan?  I can see buying a pickup if it is hard to modify, but why wouldn't you just cut and shut that pan to the configuration you want?

I ended up with two truck pans and thought I had valuable scrap.  As Clifford said, it turns out their are composite and not aluminum.  Not sure why all the shallow pans I saw at the DD dealer were aluminum. 

Gary, you asked about mileage.  According to my SilverLeaf, I have averaged 7.6 MPG over 65K miles. 

On the first Series 60, the fuel usage was spot on.  I have my Aqua-Hot and Generator on a separate tank, so only engine fuel comes out of the main tank.  I set up 4 odometers on the SilverLeaf (total miles, trip miles, daily miles, and fuel miles).  On the latter, I reset the odometer with each fill-up.  With the first engine, the gallons on the pump agreed almost exactly with the odometer.  On this engine, the fuel used seems to be more than the odometer indicates.  I now have enough data to see if the fuel usage needs to have a correction in the software. 

That said, I am pretty sure that I am averaging at least 7 MPG and probably more like 7.3 MPG.  Most of the 65K miles the bus and toad was at a weight close to 44-46K pounds (heavy toad).  Plus, we live at 7500 feet, so every trip has some hard pulls.

Gary, if the series 60 is a EGR engine don't expect 7 mpg like Jim's not going to happen all the casino buses that make the run to Phoenix are 5.8 mpg you can Prolink anyone any day of the week and it comes up 5.8 in Prevost or the MCI's

Composite pan - wow.  I would still probably make one.  The flange would be a big waste of 1/2" aluminium plate, but the rest would be a half sheet of 1/8" 6061-T6 and some tube.  Probably under $500 including tig gas and a jig, but my time would be free...
