Let me call this "my official build thread OM617 mercedes"

[jstncse]

A little Puerco action

 

[lincolnut]

Well that looks like it works...........Cool video.....

My title now says "diesel" on it and the truck is officially registered in the city of Albuquerque.

I also picked this little gem up today,

I just found your build thread. I will be hitting you up for a lot more technical information. I'm in the middle of my FJ43 swap. I will have about the same wheel base as you as well.

#1: When you moved your axle forward did that still require you to cut your oil pan? I won't have it mocked up for a few months so I'm wondering. Only moving my axle forward about 2 inches. I will have a shackle reversal and 4" lift.

#2: Where did you run your exhaust and what did you use. I'm looking for something that is as quiet as possible.

#3: How is that oil filter working out for you. It looks pretty slick. I have a remote oil filter set up but I know there are some stock sensors and check valve if I remember correctly.

#4: Did you have close ups of how you connected your throttle linkage?

#4: Done anything for RPM yet?

#5: Adapting some of the temps sensors?

I have hundreds more.

I might have gotten by without cutting it but 2" forward and 4" lift won't get you far enough away from it to be comfortable. I may have lost 1/2 a quart of oil capacity.


#2: Where did you run your exhaust and what did you use. I'm looking for something that is as quiet as possible.
I routed 2 1/4 ID pipe under the oil pan behind the sump to the driver's side then crossed back over to the passenger side over the rear axle and exited at a 45* angle behind the rear tire. I am running a small flowthrough muffler although the exhaust is fairly quiet even when straight piped.

#3: How is that oil filter working out for you. It looks pretty slick. I have a remote oil filter set up but I know there are some stock sensors and check valve if I remember correctly.
I really like it. The oil coller runs off of it along with the turbo feed and oil pressure sensor so it required less fabricating compared to aftermarket remote oil filter. Plus the way it is mounted make oil changes a breeze, I can change the oil and filter without spilling a drop of oil or even getting my hands dirty. I can't say that about my Duramax, I make a huge mess everytime I change the oil in that thing.

#4: Did you have close ups of how you connected your throttle linkage?
I'll take some pics this evening. It was fairly easy, only had to build a small bracket coming off of the engine to attach a relay rod to.

#4: Done anything for RPM yet?
I have found that 27* BTDC gives me great cruising power on the highway but is not very good for low end power. I am currently running at 18* BTDC and that gives me much better low end throttle response and power but has its disadvantages on the highway. Exhaust and engine temps are higher at cruising speeds.

#5: Adapting some of the temps sensors?
There are 3 Mercedes sensors, 2 were used for climate control system in the car and 1 for the gauge. The glowplug relay has an ambient temp sensor built into it so you can use any of the 3 locations for your gauge. I used the one behind the injection pump towards the front of the engine, I removed the Mercedes sensor and tapped the hole out to 3/8" NPT.

I have hundreds more.

Vague at best.
This is basically the same design that Mercedes used. One end of the rod is stationary on the firewall and the other end is mounted to the engine to help compensate for engine movement.

 

[addicted56]

Looks great. I'll have to take that linkage and probably copy it.

I am not quite sure about the glow plug harness yet and how we will wire that up. I believe I have all of the stock equipment from the donor car but it is just in a box I got from the PO so I haven't had time to go look at it all.

Do you have a TACH installed yet?

I watched the videos and it sounds great up on the highway. Did you just use adapters in the mercedes block to insert Toyota 2F Coolant temp senders and oil pressure senders?

Would love to see a close up of some of your motor mounts if you ever get a chance. I'll be moving my whole engine about 4" forward (using an electric fan) IOT install a 5 speed transmission. I plan on using Mercedes isolators because I have them.

How about the stock oil returns to the upper portion of the pan on the passengers side. If I remember correctly one came from Turbo and the other the air intake that collected the oil vapor.

Have you made any pump or ALDA adjustments yet? Besides advancing the timing?

How have you been doing on MPG lately? I've got a goal of 27 MPG at 55 and am hoping it is reasonable.

It is simple enough, battery hookup and a signal wire from the ignition. I used the wire that went to my HEI

Do you have a TACH installed yet?
No, that isn't on my priority list. I do run a temporary boost and electronic pyrometer. I'm looking for a permanent setup for those and a decent way to mount them.

I adapted the Mercedes fittings to pipe thread and then used the stock Toyota senders

I started out using the Mercedes mounts, they are incredibly easy to adapt but they are very soft and allowed too much engine movement for offroad use. I'm using GM motor mounts now. They transfer more vibration to the frame though

Turbo still drains to the pan and the crankcase vent is routed to the air cleaner assembly on the drivers side

Have you made any pump or ALDA adjustments yet? Besides advancing the timing?
I have adjusted the ALDA all the way out and then back in 1/2 turn. I haven't changed anything else yet

How have you been doing on MPG lately? I've got a goal of 27 MPG at 55 and am hoping it is reasonable.
I can't drive 55 and I really can't get 27 MPG either. I average about 17 27 is going to be asking alot out of any motor that is pushing a brick through the air

I got 16.2 MPG in my LX going to the Silbaughs' and back for the last meeting. That is about what I got with my HJ47, 2H, turbo and 5 speed (alhthough I got about 18 with my Vortec).

Even the blokes I know in Australia with turbo/intercooled 3Bs struggle to get much more than 20-25 MPH - bearing in mind that the speed limit there is a very strict 62 MPH, it is sea level and it is generally as flat as bad dream in Kansas.

In my experience, 27 MPG is a dream in a Cruiser, unless you run stock tires, no lift, no roof rack, bull bar or winch and no air con. However, I hope you do it!

Yeah I know. That is why it is my GOAL. I averaged 27 MPG in my Wagon at 70 MPH and the guy that bought it from me is not getting 30 even as he installed new 2.72 gears and that was with 300K original miles on it.

I figure the wind resistance at 55 is about the same as the wagon at 70 and the RPMs will be much lower. I guess we will see. Should be fun.

Thanks for the information. I won't be doing a ton of off-roading so I guess I will stick with the Mercedes mounts for now. Another 10 months and I should be on the road . If only I could work as fast as you.

Just found this thread and have this same engine in a '79 FJ55, I'm getting a lot of engine movement and was curious on your switch to the GM mounts? I'm running the stock hollow rubber mounts in re-enforced "L" brackets welded to the inside of my frame. Any info or pics on your setup?

Thanks!
Tucker

Hey Tucker,

I have checked out your piggy thread, its very nice.

I don't have any pics of my mounts but they are just mid 80's Chevrolet pickup motor mounts mounted to brackets that are welded to the frame at a 45° angle and then adapters that bolt onto the block at the original MB location. I did it during one of my several engine removals. If I was going to do it again I would use some polyurethane bushings and cage them like a Cummins mount in a Dodge.

The original MB mounts allowed the engine to move so much that my throttle linkage would fall apart out in the rocks.

 

[jstncse]

Here are pictures of my motor mounts that I took from below the engine.

Right hand side

Left hand side

Sorry for the incredibly crappy pictures

On a positive note, I got my Orion 4:1 kit from Onur at Proffitt's Cruisers this week and should have it built and installed by next weekend.

 

[evanz80]

Nice! That will get you some good low gears for the trail.

 

[DailyDrive_FJ45]

I followed this thread before the recent updates and only now got around to seeing the recent stuff. You have renewed my interest in doing this swap on my 40!

When you went SOA, and stretched the front, do you find that you have enough clearance with the oil pan now? Would you have still cut it with your current setup?

 

[jstncse]

When I swapped in my new motor I used my modified oil pan to be safe. It would be close to touching with a stock pan if the right front was compressed to the bump stop.

My FJ40 on the Jaws of Death

 

[BionicCruiser]

sweet! when did you get out there?

sweet! when did you get out there?

Yesterday.
It sure isn't an easy trail to get to. I spent weeks researching everything I could find on it, GPS'd every turn using Google Earth and every bit of information I could find and it still took us 3 hours to get to the corral and about 1/2 hour to the canyon.

Sceep's postings from back in 2005 with you and your 40 were great. We didn't have enough daylight to try the extreme part of the trail after that 20' waterfall but I want to go back in the spring or fall and try it again.

 

[BionicCruiser]

was the gate off hwy 6 open or gone? that's what usually keeps us from running it. or did you find a way around it?
