I want more torque, Cheap options?

[ThomasWatson]

hi i own a 3.0lt td gu 2 whats the best way to get more power it sucks up even the slightest hill

any suggestions would be greatly appreciated as its stock and i have read alot about upping the boost

[Bloodyaussie]

Talk to Mudski... 3inch exhaust blah blah blah..... I dont know about cheap..... 4wd and cheap dont go together!!!!

[Drewboyaus]

I reckon the cheapest way would be to sell the GU and buy a GQ!!!
LOL.
Not really helpful I know, but there are a few here that have had success improving the performance if the ZD30.
As Bloodyaussie said though, there is nothing cheap about this lifestyle.

first chip and exhaust then high flow billet MAF and alloy air cleaner housing, Bigger IC.
just out of interest how quick do you think a 3 ltr would go.
I've done plenty and happy as power to tow and overtake safely.
never ever gunna be a rocket ship, and the further you go from std the more things can go wrong

Have you installed the NADS system??
You could possibly be seeing the beginning of the end.

What ECM/Chip did you purchase, did you do any dyno before/after to see actual results? I will dyno a before and after but still new wagon (only 3,000km on her so far)....

No Dyno, just fiddling with the Dawes valve, trying to find the sweet spot. STD they say 118Kw with a DP chip 138Kw I think.
goes hard enough for my liking, efficiency is what I'm after ,
First fit the NADS, to protect your ride

Up the boost on a GU 2 ZD30 and you'll blow the engine sure as shit sticks to a blanket and there is no cheap option for more torque.

The only way is more fuel and more air by more efficient intercooling not higher boost.
Indeed NADS and Dawes valve etc is to limit boost and usually at a lower pressure than what you have now.

First mods you need to do are NADS then you can work on a Chip, bigger free flowing exhaust and better intercooler.

Other alternative is to just accept the vehicle for what it is and enjoy it. They go more than OK stock off road, aren't a sprint car on road and when towing can't pull the skin off custard at RPM below 2200

I wouldn't agree that high boost kills these motors, it's heat. By having control of boost you can bring your EGTs down which in turn allows you to put more fuel in. NADS is a must.

I'm running 18psi in mine and I rarely see EGTs go over 500°C. My probe is 50mm after the turbo.

ZD's are definitely no torque monster but in my opinion do a good job of moving a big car. There are a few guys getting really good torque numbers but as said its not cheap.

See this link for a good visual representation of boost/EGT relationship.

My Brother-in-law added a manual boost controller, and said it was like adding a second chip......I think this would be the cheapest way to improve torque, or by blocking the EGR
