factory boost for TD27T?

Dragan,

I don't know what boost your vehicle should run but the vehicle must be under load to give a boost reading. You must be driving and at different speeds and different gears will give different boost readings. The Cruiser that I own has a max boost of 12psi. All turbos can be adjusted but too high boost and the motor is under a lot of strain.

If its like most Nissans, it's probably about the 6-7psi mark from the factory.

On the subject of turbo boost on diesels - does anyone know if theres anything wrong with winding the boost up a few pounds on diesels? ie should make a little more power/torque due to more air, run a bit cooler due to running leaner on standard fuel/mixture settings? Your not likely to blow an old diesel up by going from say 6 to 10psi are you compression/reliability wise??

Cheers,
Dave.

Dragan , you should have around 4 psi standard . Did you just fit the boost guage ? if so , you have fitted it on the wrong side of the manifold

hi dragan,

Is your terrano on auto? If so do you have that that hold/auto/power switch to the left of the steering column and do you know what it does. especially the hold function.

Sorry, can't help you much with the boost question. I do have the TD27T engine manual so maybe I can look it up after work tonight and get back to you tomorrow if I find anything worthy.

TD 27t is a bit of a slug from my experience ,probably under stressed, so maybe U can lift it a few psi & benefit. Seems a big variation in boost numbers in these posts so what is a reasonable limit??? I would like to know as I have adjusted my Triton 2.5 upwards & it goes VERY well, also has a 2.5" exhaust & foam filter
& pump timing turned up a bit from factory.

I'ts probably siezed up from all that running around without oil in it !!! lol

seriously mate if it is standard then 4-6 psi is the average.
