Fitting a Boost Guage to a 3.0L TD Patrol

Sorry Flash, but have to disagree with you here. You see, a factory designed and installed turbo diesel always has a "boost compensator" on the injection pump.(some call it an "aneroid"- actually a competely different thing) No turbo pressure = no fuel boost. Simple as that.
So if you are slack enough to run with blocked air filters, the only problem you are going to see is a donk that couldn't pull a sailer off your sister. Dont believe me- well just disconnect the turbo air line to the pump compensator diaphragm and see for yourself! Of course, if its "aftermarket turbo" (as yours could be?)with no pump compensator you are in a completely different area, one I personally wouldn't venture in.

Thanks for your replies Guy's.
Just to sum up, I certainly will be fitting an EGT guage in the future, but as I'm leasing the car at this stage, I want to wait until I buy it before I start taking manifolds off to fit the EGT guage. I just thought that fitting the boost guage (that I already have) would allow me to keep an eye on things that may cause the EGT to rise and that fitting one was hopefully not as intrusive as to be taking things apart.(Drilling and tapping manifolds etc.)
I read somewhere that one of the problems with the early 3.0L patrols was that the ECU wasn't controlling boost as well as it should, and this would contribute to high EGT's, so keeping an eye on boost could help to keep EGT's down.
On my last turbo nissan (180sx) fitting the boost guage was simply a matter of cutting a 6mm rubber tube and inserting a tee piece to the guage, but it seems the patrol isn't going to be that simple.

Hi awill4x4,

Thanks for the offer to weld my intercooler, but i'm in Adelaide. I was hoping to tap into the engine side of the throttle body to get an accurate indication of the boost getting into the motor, but it looks like I may have to settle for the intercooler side. If that's the case, it may be easier to braize a fitting into the steal pipe that connects the turbo to the cooler or the cooler to the throttle body. I would assume the pressures would be the same as in the end tanks of the cooler. The problem I've found when doing it this way is that when you get off the throttle, the pressure suddenly rises untill the turbo spools down.
Thanks again,

Chaz
