TD42T Turbo Upgrade...

[DieselSmart]

The standard turbo running 14-15psi will get you around a 30% gain in power that is reliable with the addition of an intercooler.

You can get an intercooler setup, injector pump retune, boost controller for standard turbo for less than $3000. This sort of setup will guarantee reliability and give you a very noticeable difference in KW and Torque.

If you want to upgrade your turbo, you will also have to upgrade your injector pump as the standard one will only go to about 120rwkw without having to worry about reliability..

You also need to purchase a new manifold or an adapter plate for your standard manifold to support the new turbo, you will also need new oil/coolant lines for the turbo. Sometimes you may need to also change intake pipes/ intercooler pipes.

hope that helps

thanks heaps - that really explains the options... think i'll stick with std gear but run the higher boost - then fir an intercooler etc as per your comments...

And you should be able to get what he has suggested for not a lot more than $1000.

There are heaps of options available. Have you fitted a 3" exhaust and some gauges?

Dont be to worried about reliability with these engines they are built tough. A mate of mine has an 2000 model that has been running 180+rwkw for most of its life and its gone past the 400,000km mark and has never had an issue.

You wont need to upgrade the injector pump with a turbo upgrade. There are plenty of options that are better than the factory unit that work incredibly well with the standard injector pump. Its only when your getting serious about power and torque that extra fuelling will be required. (this is 200rwhp stuff though)

i need to ask a question.When I first bought my car I went over it and replaced a lot of parts. while I was doing that I had the turbo reconditioned.That was about 3/4 years ago so should I be looking at doing this again soon.Proabably only done 50k since the rebuild.And also what are the benefits of a intercooler.i don't have boost and gauges as the garrett turbo I run has a wastegate(well I have come to that cause I remember the mechanics saying that when we were looking at it)

It should be right at 50k just do regular inspections on it or get your mechanic too inspect it for you.

Intercoolers (charge air cooler) cool the heated air compressed by your turbo. When you cool it you increase the density so more air can be pushed into the cylinder. They help keep combustion temps down and improve performance.

As for gauges, it doesn't matter if your turbo has a waste gate or not (99% of turbos fitted to a td42 have a waste gate), you can keep an eye on boost levels and temperatures. It's always a good idea to fit gauges when installing a turbo so you can keep an eye on it and drive to suit.

2nd this.

Boost gauge, oil temp and egt gauages are always a good investment. your turbo should last a lot longer than 50,000k's and as nissannewby said getting it inspected when the car is serviced will help keep peace of mind.

Usually an intercooler will offer you better fuel economy and slightly more power
