That is the perfect fit vehicle for your style :smiley_drive:

Yep. His is the bluish silver 70. Not to be confused with the white or copper beige ones that also live up here...Those are just the ones I know of, there could be others.

Wow! $1,600 US for a Turbo! Must resist...for now...at least until I've done my taxes and figure out how much I get to help AIG out with....
Not much "building" to do on this rig. I've been baselining all the fluids and getting the little things done, as well as going over the rig for the Baja trip. To be honest, it's kinda nice to just have minor stuff to do...and focus on getting it ready for travel.
Just looked at installing the National Luna dual battery kit last night. Hardest thing will be figuring out where to mount the relay.
The tires are a funny story. Bull had 35x13.5 toyos on it, which were just too big for my liking. I pull into a local chain auto parts store on Tuesday, and a guy askes me about the tires...."They're coming off" I tell him...he points to a Jeep across the parking lot and says, "Well, I just bought those 33x10.5 BFG ATs last week, and I want to go with 35s."
Long story short, he trades me his brand new BFGs for the Toyos...and gives me $250 cash!
One new spare and wheel from Discount Tire, and I'm good to go! Out of pocket expense for 5 new BFG ATs....$53 for mounting/balancing.

Very cool, an absolute beauty. Really wish we could have met up while you were rolling through town by my Valentine would have had me sleeping in the tent outside 
On my shortlist of vehicles to one day own, I've spent a far amount of time traveling with a good friend and his BJ70, SOA w/60 axles (FF Rear), ARB's, 4.88's, Marks Gears, Marks Turbo, etc. What a neat rigs
How many people have asked you if its a Samurai yet?

Good looking rig Andrew. Very, very nice.
Hope to see it in person some day.

I like that one as well.
However, when you not only talked the kid out of the tires you wanted and got cash in your pocket
Tom Sawyer, The glorious whitewasher came to mind...The part where he talks all the neighborhood kids into painting the fence for him.
I raise my glass to you and smile. Well done amigo.

16 Years on ExPo. Whoa!!
Congrats!!
I have to say that in all my years of being a raging diesel fanatic one of the top 5 tricks I ever learned was before you turbo it, to pull the head (including a head gasket job) and to simply polish (and thoroughly inspect) the precups. As you tear everything down it makes it easy/inviting to remove the head, so you might as well do it then. Take even a cheapie autozone polishing kit and hook it up to a drill and polish that way. Or, take the head, have it checked and/or machined and have them do a through polishing of the precups.
Something about it makes them breathe much better and all of a sudden you are able to take much better advantage of the turbo. Almost all of the kits are great but use smaller turbos and do not breathe well for some reason. They still run high EGTs and are still slightly low on power. I learned this from the Calgary cruiser heads (Straub and Marc Ritchie). Straub was powering a BJ60 on 53" military tires using this technique. Unbelievable. He bought a 4BT to replace it but the 3B using this trick sufficed. I cannot say the experience of driving Ritchie's BJ40 with a 3B/Turbo on 38's. When boosted, felt like a V8! The BJ42 that lives in my shop (same drivetrain, also 24 volt) suffers badly from this, using a Turboglide kit.
I hope it helps!
And congrats again, wonderful truck...

Nice unit for its age.
Before you start sizing up turbos,keep in mind a standard 1HZ will probably outrun a 3B turbo.
If its a keeper ,thats the way I would go (or a 1HD T or 12HT :sombrero
There is not a lot of work in the conversion as the 7* engine bay shared probably more engines than any model

I think it was because he didn't have enough parking for the Troopy and the 70.
IIRC, his HOA dictates that vehicles must be garaged.

Gas engines take in fuel and air together and compress and use a spark plug to ignite. Diesels take in air only. They then compress the air to about 2-3 times what you'd normally see in a gas engine (so, really high pressure and heat) and the fuel injector (yes all diesels have injectors) lets out a little tift at 7 or 12 degrees or whatever before Top Dead Center (similar to timing a spark plug timing) of fuel. There is so much heat and pressure that it instantly combusts. Which is why diesels are called compression ignition engines.
There are two types, direct inject and indirect inject.
Direct inject: all activity happens in the actual cylinder itself. Usually there is a little pit in the top of the cylinder where the air goes. Here is a pic of the piston of my Cummins 4BT. It is a 3.9L 4 cyl, so nearly 1 liter of air. You have to imagine a Nalgene bottle of air (that is already pre-pressurized as much as 20 psi via the turbo before it even gets in the engine) being compressed into that tiny little cavity in the top of the cylinder:
Indirect Inject: the piston top is flat and in the head (on the other side of the head gasket from the block) is a small cavity where all that air goes, called the pre cup. Usually, the tip of the injector as well as the glow plug also comes out in the pre cup as well. Usually precups are replaceable as they occasionally crack and fail (and can end up in your cylinder.
The benefit of indirect inject: usually quieter. Still made but increasingly less and less. Drawbacks: increased heat issues (so you can only turn up limited amounts otherwise you risk cracking) and breatheability. Hence why I was suggestion polishing.
Direct inject, you can basically boost and turn up as much as possible as long as your engine bearings can take it. Usually they are louder (the Cummins as an example) but newer technology (basically anything electronic) can turn their noise down significantly.
Turbo direct inject = "TDi" which you see on the back of a Jetta for example.
