Thanks again Gerg and Dougal for all your info so far.
As mentioned in the first post, I'm not after big power, just a nice, safe, reliable increase as the HJ is my daily driver. I was originally thinking around 7-10 psi if possible.
From this thread it seems redline for a 2H is around 4100 (post 33). Also seems most have the 2h revving 2500-2800rpm when cruising on the highway. So is the 2700rpm mentioned earlier in the thread going to cause issues?
https://forum.ih8mud.com/diesel-tech-24-volts-systems/290841-max-rpms-2h-2.html
I do a fair mix of driving in it, but it would see a 2-4hr trip at 100-110km/hr a couple times a month. Also a large hill where I am maxed out in 3rd gear for a good minute or so (and doing 30km/hr under the speed limit).
Could one of you give me a quick conclusion on what I can expect if I run HX25 on the 2H?
Thanks.

With the HX25 I'd recommend you set it to around 9psi boost. You will need a wastegate unless that turbine housing is quite large. This will give you about 35% more power and torque and far better drivabililty. I wouldn't bother with an intercooler, but you will likely need to upgrade or at least recondition parts of your cooling system. 2H's have a reputation for running hot when turbocharged.
More boost is possible but that is up to you.
2,700rpm will be no problem at all. You won't hurt this turbo on this engine without doing something really silly. You will need to fit an EGT gauge with the probe in the exhaust manifold and reaching the centre of the exhaust flow. Tune it for 650C in the worst conditions and see how it goes.
I must say that I have no expereince overspooling turbos, but if your going to do it just dont jack the boost up. 9 psi is not much for these turbos considering the trim on the compressor, its designed for much higher levels. 9psi is a pretty light load on it. I wouldnt go cruising around at 3500 all day under boost though. Just to be clear the rpm max range I showed was for boosted rpm, not cruise (non boosted). I would strongly suggest that you runa good quality oil and.... give that thing a serous cleaning!

I do know that point .. and doing all sorts of mods to " control " it under boost ..

Thanks Dougal. The HJ will get a new radiator at the same time of the install. Current one is had a big hit from the fan, and outlet hose is also in the way of the power steer pump which will be getting done the same times as the turbo.
Any recommendations on the wastegate?
Seen these cheap JDM ones on ebay?

Noted, thanks Gerg.
I'll update this thread with pics of the install and feedback when the time comes.
Sorry I've got no experience with external wastegates.
That is a common Tial copy wastegate. It is actually pretty good for flow. I would say that a 38mm should be suffient for the power you want to run. I would recomend you use valve compound to "lap in " the valve for when you get it as these gates are all bling and low quality. Most have bad reps for leaking. A leak can wreck your low rpm boost pretty darn quick. Putting a granger valve in line will also help with faster spool, although your turbo will already be spooling crazy fast anyhow I have a feeling. Im interested in hearing about your results.

I've been busy on the HJ45 the last few weeks doing a 60 series power steering and disc brake conversion. I have just about finished this, so the turbo is next. I have everything needed to do the install now, so will post some build pics over the next week or two.
For now, here is some pics of the turbo cleaned up.

So the power steering and disc brake conversion ended up as a full frame off resto hence the long delay in getting back to the turbo installation.
Anyway, made some progress this week. Turbo mounted to flipped stock manifold and 3" stainless dump pipe build and exhaust to the back of the transfer case.
I've started a build thread in the 45 section if anybody wants to follow the progress.

are you going to make some sort of support to help with the turbo weight on the exhaust manifold .?
- Thread starter

Weren't planning on it, but if it is advised to, then we can come up with something?
The dump pipe and exhaust will be solid mounted to the motor/gearbox/transfer with a flex joint at the end, so some extra support will be provided there.

It lives....finally!!!
Still no wiring fitted and lots of other bits to still sort before its on the road properly, but I got it out for its first drive with the turbo, 60 series power steering and disc brakes. All went great.
Couple of dodgy videos below.

that's a beauty job .. !
On my HJ75 there wasn't enough space to flip the manifold upward so we mounted the turbo down low. Garrett turbo with Intercooler set at 10psi.

Update time!
Ute is going great. I've driven about 500kms on the turbo now with the fuel screw in the stock position (due to no boost or egt gauge fitted yet). Performance felt improved, but wasn't outstanding. At the first fill up it used around 12.5l/100km.
This week we sorted the boost and egt gauges and played with the fuel screw. 1.5 turns out to begin with, and 2 turns out now. Boost peaks at around 11-12 most of the time, but occasionally goes a little more at higher revs (turbo starts making a different squeal when doing this too, possibly due to being too small????). EGT's haven't gone much over 400c post turbo yet on a couple of long steep hills, and it soots a decent amount at gear changes.
I'm really happy with its performance now, but not sure if I should turn the fuel screw out more yet. What do you guys reckon? (Motor is worn, has some blow by, and oil pressure runs on the low line)
Couple pics of the engine bay. Still some tidying up to do, plan to get the manifold and dump pipes ceramic coated, and polish the stainless intake pipes.

You ask me .?
I would put all fuel available in .. !

Nice manifold . Was there anything in your turbo install that you would have changed or it went together well?
