I went ahead and ordered a RTT from campinglab, $700 shipped is a pretty good deal. I would love a Columbus or maggiolina but can't justify the $$ right now. I also got my Amsoil oil bypass kit. I am waiting on a tap for the turbo oil return and if it arrives today, the cruiser is going under the knife tonight for the BEB's and oil bypass install...wish me luck!

Ahh yeah it's back on. Looking forward to part 2.
How did the BEB replacement go?

it didn't! the tap didn't show up until Thursday, and I decided to order a new drill bit for the turbo oil return and do that while the oil pan is off. I pick up the drill bit monday and plan to start it that evening. I reinstalled my mechanical oil pressure sensor in anticipation and i hope all goes well. It'll be interesting to see how the OE bearings have worn now that the engine has over 100k miles on it now...we'll see!
Well hopefully it goes well! Are the BEB issues just a 1HZ thing?

no actually a 1HD-T thing. But i believe the bearings were the same on the 1HZ (though without the problem reports), and as a precaution I figure I'd change them out especially since I am adding a turbo.

Thanks to Gary (rapovt) for letting me use his shop, the new BEBs and the oil bypass kit are in and the block is drilled and tapped for the turbo. All the crank journals/old bearings checked out fine with the plastigage and the old bearings actually looked pretty good for 120k miles. I'll take some pics later. Runs great so far!
Sweet. When's the turbo going in?

I still need to order my gauges, some exhaust tubing and figure out how to route the turbo with future sliders, which should give me time to break in the bearings somewhat. But, I want it on and running in two weeks to give me time to tune it and work out the bugs before I leave after july 4th...!
You should be able to get it on in 2 weeks. If you have the intake all figured out already then the exhaust will be the only hard part.
Two weeks is a good goal. I'll be tuned in, and good luck!
so when's the trip to nashville for the sliders?
been able to get my hands on some decently priced DOM lately...

i'll have to get back to you about that...
Gehn where are the pics. I know your working on something.

Okay, okay...First of all here are the BEB's. A little wear but nothing i wouldn't expect after 120k miles. No excessive pitting or scoring either but I'm glad I did it anyway. I have over 200 miles on the new ones now and all is well.

More importantly, I installed the turbo! So far, I am really pleased with this kit. I started with replacing the intake gaskets. These didn't come with the kit, but due to the higher mileage i figured it couldn't hurt.
The start
Intake off
Old vs New
Intake back on
The kit came with a new front exhaust manifold with the correct flange for the CT26. I tapped it for the pyro, and then reused the old rear manifold.
I re-assembled the turbo to the exhaust manilfolds and installed it all at once. In retrospect I should have bought all new exhaust manifold studs, but fortunately I didn't strip or break any.
A buddy who came by to help out
Turbo Assy in!
Intake hoses installed
I was a little nervous about taking apart the injection pump to install the boost compensator but it really wasn't too bad since it was just a matter of swapping out the top cover.
With the turbo in, I wired up all the new autometer gauges (boost, EGT, oil pressure). Since the stereo was moved to the console, I made a "custom" panel out of aluminum to mount them in the stock radio spot. They came out pretty well. For the factory look, I used the green bulb covers they came with and I wired to the OE dash light dimmer.
in place
Here's a pic of the Amsoil bypass filter which installed earlier which feeds the turbo with extra clean oil.
It took a little while to get it started initially. I was careful to replace my full-load adjustment screw at exactly the same depth as it was in the old injection pump cover, but apparently the two are calibrated completely different. I ended up having to turn it in about 2-1/4 turns to get it to start, and then another 1/2 after the tune. Out of the box the actuator is set for 8 psi, which is fine for now. I tuned the injection pump accordingly and I am very pleased with the result. I can actually accelerate up hills now! In time, I hope to run about 12-15psi but I want to go slow for break in and see how my fuel mileage is affected as I go.
That being said, I should have done this years ago...
congrats bud!

Thanks for the turbo info. I have a HZJ105 for expeditions... and really need some boost.
Please, how do you find the exact amount of diesel to 8 psi (injection pump tune)
Thanks,
I'm loving your project.

I tuned the fuel by the pyrometer. Turning up the fuel creates power and heat, so i tuned it according to my EGT (exhaust gas temperatures). A rule of thump is about 1200F max on long hill climbs.
