Anyone have such a setup? What kind of boost can be expected from this turbo? At which RPM? Can boost be adjusted? Any comments overall?

Thanks.

I don't fit the DTS system as I fit the Denco systems however I do have a few customers with the DTS set up already fitted.
I would strongly suggest you don't go over 8psi boost on the 1HZ.
Yes it is adjustable.
What RPM? Don't know but the Denco comes in very early.
I would strongly STRONGLY advise you to fit an EGT guage and DO NOT let the temps get over 500 degrees if it is fitted directly after the turbo.
The DTS seems well suited for the 1HZ engine.

Thanks for useful info. Trouble is mine doing only 3psi @ reasonably high RPM (have not tested it exactelly, but it is high) and I just service it. Because engine doing very well, I plan to go 5, max 6 psi. So how I can adjust it? And sorry my stupidity, but what is EGT guage? My best guess is that it is a termoguage fited in exaust pipe imediatelly after turbo. And BTW I do have hole there.

Exhaust Gas Temperature, measured by a pyrometer or some such thing.

I put a DTS system on an 80 Series that haddone 250k klms I did another 100k before I sold it. Transformed the 1HZ motor. The only problem I had was it cracked an engine pipe but that was an installation fault. They are cheap too TJM were selling them for $2600. Cheers Rob

I have a DTS turbo intercooled setup with a boost compensator on the fuel pump. I run 15psi boost and have done so for over 2 years with no problem at all.
The transformation is huge.
However I do intend to reduce the boost pressure back to 10psi and recalibrate the pump. I want to see if I can get better fuel econmy than I am now. I currently get aroun 13l/per 100km city driving.

Quite interesting. Everybody said 8-10 psi max and 12 psi will kill engine in no time. How often do you change oil?

I change the oil and filter every 5000km's, But I've done that with every diesel I've owned.

I rarely need to go to 15psi, mainly when I get to 10psi on the gauge I decied if I need to go any higher and use the right foot to keep the boost at around the 10psi range.
I don't know if the intercooler makes much difference as I have never ahd the cruiser without it.
I do now some people who run 18psi and over in comps rigs and these engines also seem to last if they are cared for properly
