2004 Patrol 3.0Ltr Additional Power/Torque

There is a lot of experience over at http://www.patrol4x4.com/forum/ including how to prevent yours from imploding as many have done, before you go hunting for more power.

The gains to be made from the 3 litre are in my view not worth the expense or risk. There are many mods on the site mentioned above but most of them are to eliminate what the owners see as an unacceptable risk of a terminal engine failure.

6.2 lt Chev, roughly $20,000, 10 times the power, excellent value for money.

Prices are Chip $1300-$1600
Exhaust $1000- $1500
LPG $3000-$4000 minus rebate maybe


New engine 6 months later $8000- $15000

LOL

What the guys say is good advice

None of the options your looking at will fix the lack of torque and power below the 2000rpm range of your donk

Hi Rob,

Asking for info about the GU 3.0TD Nissan brings a howl of disaster on this forum! While this motor does has more than its fair share of problems, a bunch of owners have pretty much worked out how to fix what Nissan should have done originally. Jump on to the Patrol forum and you will find a wealth of info there.

I used to own a 2003 GU and went thru the same questions you have. I had a snorkel fitted from new, but that was for water crossing insurance and not for power gains (won't help power IMHO).

I fitted a Dtronic and found it had a significant improvement. It certainly helped the bottom end power, especially the 900 - 1500rpm band. Less than 900rpm was still an issue (comparing to my old 1HZ 80 series).

After reading about the EGR and MAF issues, I blocked my EGR valve and never looked back. This significantly improved any turbo lag and I kept the vehicle like this for 5 years. I was very happy with the power and economy, and while the bottom end power wasn't quite what I would like, it was acceptable. I never had an issue with motor reliability (but do acknowledge others have).

Now others in my 4WD club have also added the big bore exhaust and LPG gas and they were of the opinion that if they had their time again they would do the following in this order;
1) EGR block (free)
2) Dtronic (~$500 2nd hand - $1400 new)
3) Big bore exhaust (~$1000).

Those who did the LPG gas wouldn't do it again, not only did they have issues with reliability (mainly installation related issues) but the need to fill with diesel then move to the LPG bowser meant they often didn't fill the LPG tank, (as well as availability in places). Also, the loss of the sub tank affects range.

I have a large pdf file (~7Mb) from the Patrol forum that has been complied from owners around the world for 3.0TD fixes. if you want a copy, get my email address from my profile below and let me know.

Cheers

Captain
