I am really enjoying this build so far.
The fact you can get upwards 250hp out of the 4cyl is sweet.
Keep up the good work.

I like parties at other peoples places.
The TD04HL-19T is capable of maxing out the stock injection pump by itself, so the main attraction of compounds should be high altitude and really low rpm drivability.
Having said that, John on 4BTswaps just found a company offering 12mm pump elements for these, should be a nice upgrade from the original 9.5mm ones.

You are welcome to swing by lol, bit of a trip for your though.
I think the TD04HL-19T will work out really well, I have an auto so I cant see missing a lot in the low end since it will be pre converter stall. By 1500RPM I'm sure it will be singing away.
I did e-mail them and have yet to hear anything back about the 12mm pump parts.

Thanks, yes 250 diesel hp would be outstanding but I'm not shooting for that. It needs to be reliable and efficient first and foremost. Having said that I do have unlimited access to a Dyno Dynamics Dyno to test it all out. I am doing a pre swap 1FZ dyno and will also do a post swap 4BD dyno to get a feel for there differences.

So I ordered another Volvo TD04HL-13G turbo. This one has the newer style turbine outlet flange. I was looking at mine last night and the housing is very restrictive ones the gasses leave the turbine wheel. I can see this being a problem if I want to maximize the performance out of this engine and turbo. On the housing I have not I was only able to fit a 2.5" vband the new one comes with a much larger outlet 3-3.5" so will work much better I think and be easier to build my 3" exhaust off of.

A secondary benifit of getting the 2nd turbo is I can use it as a small turbo in a compund setup....Gerg.......
I also happen to have a 2.5" weld Ell that I can use for the small turbine to large turbine connection. Possible use a HX35 as the larger turbo in the pair. Both turbo's would be used as is so no rebuild or money invested. I'm not sure how the TD04HL-13G will do as a smaller turbo in a compound set-up, the shafts on the TD04's are a mite small. I will have a compressor wheel filter in the system though (intercooler 
)

I will have a compressor wheel filter in the system though (intercooler )
So the 7 blade hx35 wheel flows enough for 20 psi compounded to 3500rpm with peak torque right in the middle of the effeciency (76%) island. It maps extremely well... hint hint. Older 8 blade also has great numbers but not as high rpms... 3200 or so it seems. I have read that 3.9 guys have a hard time spooling the twin scroll hx35s compounded as it might be a tad too much housing, although I do love the twin scroll idea for effeciency. I just happen to have a hy35 7 blade in my garage Ill bring over tomorrow. Its a hx35 except it has a 9cm single scroll housing as opposed to the 12cm twin scroll.
The 13g compressor would work well as small turbo in a compound boosting 1.5pr or so. Again drops peak torque right in the middle for effeciency (78%), holds on the map to over 3500rpm. This mapping was for setups pushing a range of 30-50psi. Large doing 20 with small doing 1.3 to 1.9 pr. I dont know what crazy torque would be applied to the shaft, but it would be signifigant and tnot good at all at 50psi to say the least. I could see it being quite a nice set up for in the 30s though.
The 19t would work, but is not as effecient as the 13g with the hot intake and the low pressure ratios.
edit. Ok so I got a few numbers screwd up as in russing out to cut the grass. At lower boost (30psi) you can easily hold the 13g/7 blade to 4000rpms. As you incease small turbo boost you loose rpms to prevent over spool of the large turbo. This decreases down to 3300 at high boost.

Hehehe I knew you had already worked this all out
Bring the Hy35 tomorrow and we can play around with it a bit. I think 40-50psi is to much for the TD04 shaft and my transmission for that matter.
I do not think the 19T would be a good option for a compound set-up but I maybe wrong if its like the HE221 a few have got and used on compound set-ups it maybe ok. I still do not plan on doing it but fitting it up and seeing how its fits will help you when the time comes for compound 4BD1T in your 80

Yeah I just cant help myself. This is all theoretical by the way, but the maps show lots of margin on eithr side, so that is comforting. Sees ya tomorrow.

I didn't realise you two were so close. This could get interesting.
Yeah live about 20min away from each other.

OK was able to put a full day in the garage today. I first started by removing the VB from my A440F for modification. Got it out and everything looked good.
So I moved onto my filter relocation system first I got a 1/2 NPT plug and a 1/4 NPT plug as well as a 23/32 drill bit. I then started the task of drilling a hole through 7" of aluminum.
Pilot hole:
Bigger 23/32nd hole:
What this picture does not show is the 2.5hours it took to drill it. My drill press has 3" of movement and I needed to continually move the base up and down to clear the bit as it would get plugged up. The outcome was worth it though, I have already found a few ways to make the process less painful when I make another.
Drilling the holes into the journal.
Taping it to 1/2 NPT:
Brass plug installed. Correct me if I'm wrong but is it bad to have brass and Aluminum in contact? I seem to recall that that brass has a higher natural voltage than Aluminum and they will eat each other.
Test fit:
Test fit with filters:
Will need to adjust the fuel feed and return slightly:
Moved up a good bit and I think will be enough room for the Hi pinion diff:
Next on the list was the small oil feed off the filter assembly that feeds the injection pump and front of timing case. I was planing on using AN lines and remaking it all but I have to say with a few minor bends its about perfect.

No contacts at all:
I have at least 1/4" clearance everywhere around this line, it took so little bending I cant believe how well it fit.
Now it was time to move onto the hard one, the main oil galley line from the filters to the oil cooler. I again planed to make this out of some AN fittings (and still may)
I decided to cut up the stock line and see what I could piece together.
Not sure how much I like that line yet. I will need to build a jig so I can take it to get TIG welded.
Finally I got a measurement from stock mounting point on the block to the outside edge of the filter mount.
About 6 1/4" After talking to a friend with a 4BD in his 80 series there is up to 8" of frame clearance so it may just work!!
Really happy how this has come together, got to love those sleepless late night brain storms. I hope to drill the bypass filter hole tomorrow.

Greg also stopped by for a bit and checked things out, we looked at the HY35 and there is not going to be any easy way to fit it with the starter where it is and the limited space on the drivers side wheel well. So I am sticking with my TD04HL-19T and hope its preforms well.
Should have the 2nd Volvo turbo I ordered here in a week then I can get back on the turbo fitment and installation.

So you did get some work done after I left. Looks good. You need a mill drill!

Yeah got a bit done, trying to focus on one thing at a time has been a challenge. I should have most of this relocation bracket done tomorrow. Just need to drill that one last hole, its going to be a pain. Yes I do need a mill.......badly but you saw my limited work space so its not going to happen. My main problem is once the drill goes deep enough it cant clear the fillings out and jams up. So i need to drop the deck and take the part out to clean it. Needs to be done about every 5mm of depth drilled = big pain in the ass when drilling 130mm +
Hy35 would be a bit too big for this motor unless the fuel is turned way up, no?
- Thread starter

Yes it is, we where looking at compound setups. It would have been the larger of the two. There just is not going to be room to easily fit them with the starter right below and the limited firewall room.
Turning fuel up does not make a turbo shrink.
HY35 is too big for any 4 litre diesel.
