Finally picked up my 700 Diesel. Mod time!
 
Over the weekend, I made the trek from Ohio down to Lawton Oklahoma to pick the big girl up. 2200 miles in 3 days wasn't actually that terrible.

The owner bought it brand new in 08 in Alaska for moose hunting but then got re-stationed in Oklahoma 6 months later. He said it was one of only 4 to get delivered to AK. Since he never used it in OK and is getting deployed june 15th, he put it on Craig's list and I happened to find it the same day. The rest is history now Cat happy.

The previous owner kept it so clean it's not even funny. It never saw a night outside, rain or mud. Only snow and desert dirt. It looks brand new everywhere except for a couple light branch scratches on the plastic and racks. The brake rotors were actually slightly rusty from sitting in the garage so much haha.

Came as pictured including the 28" mud hogs with a brand new matching spare and a hard gun case with the speedrack mounts.

Stopped at Meramec cavers in Missouri on the way back. It barely fit on my 5x8 trailer haha.

Since the previous owner left it bone stock mechanically and I run a diesel shop, it couldn't stay that way! The thing was so slow it's not even right. I don't know how the PO drove it 400 miles that way haha.

The day after I got home from the trip, I bumped timing a few degrees, adjusted the injector link bar, and gave the torque limiter screw a few turns till we got a few puffs of black. It's not a rocketship by any means, but it'll actually spin tires on dirt now. It's acceptable for the moment.

While I was at it, I removed the spark arrestor and welded on a piece of scrap 1.5" SS tube. Used a cut off wheel on the factory tip to mimic mine. Some black engine enamel finished it off. Snorkels are next :thumbguy:

Once I catch up on work at the shop, I'll play with the high idle setting/governor weights to get up to 4200-4400 rpms. I need to get the valve spring specs to make sure we won't have any valve float first though. Once I get that figured out, there's no reason this thing can't turn a few more revs. IDI diesels love rpm's and this thing is built so stoutly it won't be an issue mechanically.

The last thing I'm planning to do before fall is give it what every diesel needs, boost grbanman! Going to grab one of these little guys and go to town. RHB31 Motorcycle Turbocharger Quad Small Turbo RHB3 | eBay . I'll be sure to post up lots of pics in this thread when I do it. Hardest part looks like it's going to be hiding all the pipes under the plastic.




I'm glad to finally have a Green machine again and be back with the crowd Rockerdude. Been 4 years since my 02 400 4x4 was totaled by a friend and I always had the itch for another AC.

i think the car should be on the trailer and the quad toeing the car home. The cat is bigger then the car :D

Nice ride man! I love those diesels.

Looks great... you mentioned getting some pep back, but I'm more interested in the bottom end... how does it pull?

Also, what kind of tires are those? I can't really tell from the pics. They look like a swamp wtich knock off.

Cat probably has more torque too lol

do a propane injection set up , that will wake it up

With stock fuel settings, it was as slow as a slug. It didn't really feel torquey at all either, but then again I haven't had the chance to hook it to any load. With the fuel screw on the side of the head turned in a couple turns and the timing bumped ~3 degrees, it actually feels like it has some oompf now. I'd love to find a atv sled pull near me and see how it does against gassers with a load behind it.

The tires are GBC mud hogs I believe. They're definitely chunky.

Nahhh, that's a sleeper jetta TDI (diesel). It has an aggressive tune, big injectors, cam, big turbo, monster factory front intercooler, 3" stainless exhaust, and a 6 speed manual swapped in. It dyno'ed a couple weeks ago at 220whp and 395 ft/lbs. Not bad for a little 1.9L 4 banger Rockerdude.

No thanks, IDI diesels don't like propane very much. Their compression is high enough that they will ignite the propane before fuel is injected basically causing detonation. A DI diesel has a lower compression ratio and is more tolerant to propane, but you can still overdo it very easily. I'd rather not melt a piston in this kitty cat. A turbo should be more than enough for me until I find some larger injector nozzles out of one of the 4 cylinder turbo'ed Lombardini's.

Hey man off topic question to the op. Do you have any tricks for a kubota rtv. It's just like you described. You would think a three cylinder diesel would put out more umph.

It would have a little more oompf if the emissions gestapo didn't get their hands in there before it left the factory.

First and foremost, get a factory service manual. From there, follow directions to advance timing ~3-4 degrees as a general starting point. Next, find the main fuel screw (commonly called the torque limiter screw) which will most likely be under some kind of tamper proof cover. The service manual will probably tell you to screw it CCW to "reduce complaints of black smoke". So you'll want to screw it the opposite way until you get a light haze Rockerdude. That'll keep egt's in check under load.

I like it. I take also would be better to open up exhaust and air as would normally on any engine.
