No I have not seen that thread....

That shop was at my school, and very very limited in machinery and tooling, our pride and joy was a HAAS CNC minimill that the shop manager did nothing to take care of and was getting pretty rough.

All my motor mount stuff I designed on Solidoworks and sent the drawings to a laser cutter/bender, and they did it for me. They were laser cut from 3/16" steel, and they have some type of automated bender to bend stuff up, then I welded them together.

I would say like 2.5" high, 24-30" long, somehwhere around there

Some don't seem to honor it while others do.
Every little bit saved helps.
Save a little on a battery or two.
CNC mills are pretty neat.
Wish we had one.
But machinery doesn't last long without maintenance.
I picked up a kwik way model f boring bar for $350 to bore my 258, he was selling it because he was getting to old to work on engines anymore and his hands couldn't hold anything steady anymore.
I am pretty sure that machine has been dropped at least once because the rod that spins the cutter is bent and there was no oil in the transmission when we bought it.
It still runs well considering it is at least 50 years old but occasionally it starts acting strange on us.
When I have some free time I'll try to make up a template for the sticker and see if I can make a sticker that looks good and send it to you.
24" is the max it can go across so it might be a little smaller than you would like, I'll see what I can do.
Hmm guess I need to ask a couple other questions.
If I can get it to work and make a good template, do you want flat or shiny in black or white?
Also you just want a plain font or a military stencil font?
Once I get a good template I'll use a roll of paper and a pen in the machine and have it sketch out what it would look like.

I have no idea about the deactivation, I don't think it does. If it did it would be some internal mechanical set up, but I really do not know.
Its computer controlled it just turns off te injectors.

That is for a common rail system with electronic injectors. The tb4 is fuel pump (mechanical) controlled injectors. Now he could do a compression release but then the would require a lot of work.

yea these motors are completely mechanical, the only thing they need to run is power to the fuel shutoff solenoid, no computers or anything.

This thing fires right up, I do not thing I am going to have any starting issue with it. I read somehwere that it is rated to start normally at like -10 degrees F, assuming the fuel is not frozen haha.

Sweet! I'm so glad to see this finally on here! Thanks for the help with planning my 4bt swap and it's so much nicer to see some pics.

But I'm going to look at another YJ this weekend that we might buy that I can do the swap on and yet still have my YJ as my DD...right after I rebuild the trans in it. As soon as I get my jeep solid for a DD then I'll really hunker down with the projects and get some black smoke and spoolin turbo.

Btw, I dont remember what you said you were going to do for vaccume pump to create usable vacume...I'm thinking about going with an electric one, at first I was going to go with a serpentine system but it's just not worth it, free up some power and fuel milage and make it a bit easier with the brackets.

Actually there's an easier way to do the brakes if you got some good junkyards nearby. Mainly, use the power steering instead. A lot of RV's and buses do that - they tap off the power steering pump into a special brake booster. Lots of diesel pickups from the 1980's and 1990's do that too. Look for anything with dually rear and diesel and it'll have what you need. Like an old school bus or something.

Sounds like a pretty good plan you got going there.
175 sounds reasonable for custom motor mounts for a heavy 4 cylinder diesel engine.
Hope it all goes well.
It'd be pretty cool if JD started using yours for their swaps.

I would not mind working with JD, maybe I will get in contact with them, They are not too far from my hometown, but I want to try things on my own for a bit.

I would actually really be interested to see if my mounts reduce vibrations over theirs.

Wow, $175 is a steal. I would love to get a set, I might even buy a set ahead of time before I really get into my project. If your making and selling the mounts how about you supply other hardware and parts needed to do a 4bt swap, like let the customer pick their own 4bt to save costs and the transmission as well as transfer case but supply the brackets and odds and ends to mount it all up so you could just supply the cheaper stuff and let the customer shop for the more expensive parts.

But have you thought about propane or even methane injection? I would imagine its possible on the 4bt but I'm not sure, I dont see why it wouldnt, my uncle's powerstroke V12 has it and it's a real power booster when tuned in well with the turbo.

What's the boost run at stock? I heard 13lbs but what turbo is mated to it? Sorry for all the questions, normally I research it but it's been crunch time for me at school.
