Ive been driving the rig around town all week and put about 200 miles on it. My brother arrived here in Portland Thursday night and we have been working non stop to tie up loose ends
In the past few days we installed water, oil, and pyro guages permanently.
We also built a wire harness for the edic (between edic motor and edic relay). We spent a bit of time on this partly because I re-assembled the edic motor incorrectly. I had to take a working one apart to compare and got it working.
EGT has been a little high. Its easy to get to 1200 so we may turn it down a bit. There has been no smoke at all and oil pressure is great.
Last weekend I installed an OME lift and 33x12.5 tires with new rims. At this time I replaced the front axle with one from an FJ62 and replaced the rear diff with 4.11 from the same 62.
Tomorrow we leave for the 2400 mile trip from Oregon to Indiana.
Here is a pic with some temporary 32" tires on it. Ill post some pics of other parts of the process after the 25th.

Awesome......way to go converting!
1200 is pretty easy in a non turbo 3b. Just dial the fuel down a bit. The stop at your edic arm is where to do it. you will see the big nut and flat head screw. In makes it cooler I think, out increases.. but I may be confused. Been awhile since I fiddled with my fuel.

drool-
Looks great.
I hope to have a lift and a 5 speed one day.
Have a safe trip and a Happy Thanks Giving.

We made it!
Well the rig made it with no real issues. 2275 miles or so. We had a little water leakage around the thermo housing and from some bad top seams on the radiator, but it wasnt enough to cause an issue. There was also a little oil leakage from the oil lines near the oil filter and the rear main, but again nothing serious.
We adjusted the fuel down one full turn after the first tank in central OR. It was running too hot on the EGT. We later adusted it back up 1/2 turn after we passed the the highest point of the trip (8600 ft) in eastern Wyoming near the halfway point of the trip. Roughly half the trip was uphill.
Our mileage over the whole trip was just under 19 US gallons/mile. Ill post details later.
There are some issues that I would like some feedback on.
1. The engine idles very rough between 750-950 RPM. Its enough to make the steering wheel rattle. If you set the hand throttle at 900 + its pretty smooth.
2. This setup has NO POWER in the top end. We had a tough time maintaining 65 mph which was about the max top speed we could do . It seemed as if the top speed was directly controlled by the adjustment of the fuel stop on the pump ( which makes some sense). 65 mph in fifth gear put us about 2300 RPM.
I have had two other 3B powered cruisers for almost 10 years and they both have much more top end than this setup currently does - with lower EGT.
The 60 weighed 5900lbs with us, fuel and the load we were carrying. Last summer and many summers previous I have taken my BJ75 on 1500 mile expeditions with loaded weight as high as 7100lbs and had no trouble doing 70-75 mph with little trouble with EGT (and a 4 speed trans to boot) . My 75 is a similar setup with 33x10.5 tires and 4.1 gearing.
What should we look into? There has been no smoke from the 60 conversion. The engine tested at 410-420lbs compression. The only thing we have not checked is the injectors, but I would suspect smoke with the EGT we were getting if the injectors were bad. Could it be that the injector opening pressure is too low and causing an issue with timing? We did check the pump timing per the FSM and it was dead on.
Thanks

Did you end up having the injectors or pump looked at? I suspect this is close to being a good runner as there is no smoke or oil usage(assumed)

The injectors were redone. According to my brother it did make a difference, but I have not driven it since then. He said its smoother and has a bit different power.
Regarding the vibration: The engine was installed using the 2F engine mounts (insulators) and they were hard as a rock. My brother has new 3B insulators to install and I suspect that would clear up most of the rattles. They are thicker and softer. The engines in my 70 series move around a lot in comparison.
Regarding the statements above about 65 mph top end - we were driving at altitude for the majority of this trip. The 3B rigs I was comparing to both have less wind area (less drag) and 65 seems to be a similar speed that others report with BJ60's.
My brother should add something to this.
BTW he has a 13BT manifold and supra turbo that will probably go on the 60 in the next month or so.

Turbo Time!
Truck running great, Pyro's down across the board after the injector rebuild, been a few months and a few thousand miles. Seems to have more power and runs smoother. I have the new motor mounts that will be going in in the next few weeks which will help with the vibration.
The truck is still for sale and in the next few weeks the Turbo will be installed. I have all the parts for the install, just need to get the time. I will be having surgery 6/30 so plans are to install the turbo shortly after. I'll keep you posted

speed
The truck will cruise all day long at 65mph, just remember it's flat as hell where I live and we are maybe 600 feet above sea level.
