FOCKIN' TEASE!
I am trying to convince my friend to be less picky with the pictures but he won't send them to me
oh well, looks like I'll just have to take it out again...
For you non-metric folk, it seems that 100km / 10 Liters shakes out to about 23.5 mpg. Holy awesome.

Just got back from a trip, 230km on the highway, 70km of 4x4 so 300km total for 30 liters of fuel to top the tank back up. I am very happy about this considering I was not going for fuel economy on the drive.
I did have one exciting thing happen on the trip. The last hill in to Squamish starts in a 50km/h zone, hill starts and then transitions to an 80 or 90km/h zone. I was behind traffic, so we were doing a little under 50, by the top of the hill we were doing 115km/h and it was still pulling hard when the coupling on the inter-cooler let go.
Last time I heard a bang that loud was when I threw a rod through the block. It was raining this time so there was a visible shock-wave that came out the front of the truck. Pulled over to wipe my ass and had it re-connected in 10 min to continue the trip!

Nice! Looks like an awesome rig.

Update:
It has been driving well. Fuel economy was 25mpg on a long road trip back, and has been no less than 20 mpg daily driving and off road. I can't seem to drive it with the goal of fuel economy yet, it is too fun to drive.
I get a puff of black smoke if I start in 2nd at full throttle, but other then that it burns clean. There is a fair amount of more power screw left, however I am finding my egts are a creeping up there at the end of 4th gear on long hard pulls; with the egt needle seeming to move quickly to 1,250 before I back off. I am not willing to push it to find out if it is safe. My boost on those pulls is 25psi and the wastegate is opening. I am having a lot of trouble with the kinugawa springs for the wastegate, none of them are what they say they are. I am on my 3rd 28.8 psi spring and it is the highest one yet @ 25psi. Just now I set the tension on the spring a bit tighter with the goal to make it open closer to 28psi, I am hoping that makes big enough difference with egts.
I am running the TD04HL-19T.
I know at this point if the extra boost doesn't make a big enough difference I need to turn the fuel down, but I realy don't want to... I have this terrible desire to turn it up.
Looking for input.
and I don't take too many photos, but this is from this weekend.

Got intercooler? Might be time to step up the turbo department. My td04 (non waste gate) at 25 psi would still leave my mitsubishi smoking a bit during heavy acceleration. Egts would climb as well.
I like the he351ve much better. 25 psi with it is a lot more than 25 psi from the td04.

It has got a pretty big intercooler on it, I think you are right about an increase in the turbo size. I'll look into the HE351VE.

Love it
What intercooler are you using? I can see it poking out through the grill in the first pic.
Great question, I will find out.
Your rig has booty! It sounds so good! Now I want to install a bigger engine in my bj60
The HE351 is too big. You'll lose all low end and suffer with smoke and high EGT.
There isn't a good turbo that's just one step up. There are some TD05H and TD06H options but the compressors aren't a great fit for high boost.
Might just have to compound that TD04HL!
The VGT HE351VE is not too big. I can choke the turbine ring down far enough where it's spooling making 5 psi at idle! Spool is fantastic with this turbo, IF it's set up right. People use this turbo on 2 liter eclipses and spool just fine.
Keep in mind this is a 4.3 liter engine, mine is only 5 liters.
Only downside is you'll end up making some extra drive pressure, again depending how its set up.
I would only do the vgt if you can find one cheap.

It's the compressor that is the problem. It won't be able to produce more than 20psi by 2000rpm without being completely in surge (not eve on the compressor map). Even if you can avoid the surging boost, you are operating in a point of about 50% compressor efficiency.
Bigger is not better with turbos. They need to be the right size or both fuel economy and drivability turn to custard.
