Turbo Info

[nissannewby]

Its a 4.2 turbo intercooled 2003 model.Three inch exhaust .Just want to get set up for towing mainly.

Fairly stock then. Do you have a copy of the dyno? Do you know if the timing was adjusted when they tuned it?

There are 2 options I think will work for you if I cant help point you in the right direction with your current setup.

Ok. The injector pumps on these motors can be a bit funny if the timing is altered to much. It can have undesirable effects as you describe.

You could swap the turbo and for the most part it will be better but you wont see its full potential if the pump is playing up. @MudRunnerTD knows about getting the timing set right on a td42ti motor.

It is usually evident on the dyno run so if you could get a copy then it will go a long way to giving you a more precise outcome.

Your dyno tuner should.be able to just press print. There is no reason why they cant supply it. Your log will be saved against your regi nu.ber and should be readily available. Event if you go in there and ask them to pull it up and take a photo of it will help a lot.

Newby is your man mate. If your timing had been altered it will cause heaps of issues and can really hold the engine back.

Follow through with the dyno print before spending money.
