Yesterday I admired a mechanic's 79 series dual cab trayback that was only 5000k's old and he offered me a drive. Yes thanks I yelled back.
This thing had more grunt than any 4WD I have driven. He had fitted a "chip", 75mm straight through exhaust and a K & N air filter and it must have been up around
230 KW and 600NM. It pulled away from 50 in 5th with no effort whatever. It was just like driving an American V8 pertrol something.
Note to self. Sell our 80 series and go looking for a 76 series that needs a little boost.

Sometime time ago I was enquiring at a car yard in Perth regarding a 2008 model V8 Troopy they were selling - had a new Toyota V8 diesel fitted at 140,000ks. The original motor had been chipped and self-destructed. I have the same model - it’s not something I would do.

One does not hear of chipped engines self destruct. Many many on this forum and others have chips
Are you sure thats why the engine self destructed?

In this case the torque has increased 45% and power output by 50%.
You are stressing the engine components and driveline components way above their design capacity.
Some people get away with it, some don’t – it’s a risk.

Out of a single turbo without going overboard with after market parts, those figures are a bit over the top...... I would say 10% more power and torque but with improved response and drivability.

I assume you talking about Whirlwinder’s figures– my percentages are calculated from Whirlwinder’s quoted 230 kw and 600 nm (quite amazing if accurate).

No, Fisho, that's the one I meant!

Have heard your quote before, but the other has been around almost forever :-)

Googled it just now, in case it was attributed to someone(a Yank obviously) but seems to have been in general use, maybe since Henry started producing bent 8's back in the '30's?

Your quote was mentioned too, a more refined version someone suggested.

Found this on same web page:

The Wells Law of Engine Size

If it matters what gear it's in, the engines too small.

I drive them at work there not to bad but there behind there way eight ball if you compare it to the 3 ltr Navara V6 diesel which has 170kw - 550nm as standard. Toyota need to pick their act up a bit. I would keep the 80 ser which has more room and is a lot more comfortable and capable off road than the re- badged European 4 door Prado which is sold here as 76 ser and hasn't improved since they started making it in the mid 90's.

I'd agree on the 76 series body, what a shocker for room. Reminds me of an early model Pajaro.

The peak figures can be misleading but help sell Navaras.
The Toyota 70series V8 gets max torque at just 1200rpm.
Navara doesn't get it until 1750rpm.
If you'd like 650nM at 1600rpm replace your 80series with a 200series.

Yes max power figures are really only of use to the marketing department for advertising, it is when you get the power that matters.
Fair call on the 76 but you have to remember it is made for a different market and not meant to be compared to Pajeros etc, they have a Prado and a 200 series to meet those clients needs.
It is a lazy unstressed motor though

LOL. Member Sludgy recently sold his Troopy and bought a 79Series Ute. He had it chipped and 3"exhaust, etc. Said to me, after I rocked up in my 75 series unturbo'd Troopy, jump in and take it for a spin. Bastard now I want one!

Hell that thing has got some serious get up and go and the scary thing was that the chip wasn't wound up for maximum power. The ride and comfort was also impressive.

Yep now I'm going to have a bugger of a job convincing my wife that I really should have one.

I put an exahsut and chip on the 79n series 3 years ago and haven't been disappointed. Below is the write up from my blog regarding the ute build;

Building the dream off-roader

May 2011; I have just had the performance modifications made to the ute. A 3.5 inch Taipan exhaust was fitted together with a chip and an EGT gauge. The fitment of the exhaust was not without its difficulties due to the stretch and the confining nature of the big rear tank but it was all made to fit in the end. The overall change has been absolutely incredible. It’s gone from Moose to Gazelle. It freakin FLIES! I have had it tuned specifically to assist with the heavy weight of the vehicle and towing. The work was undertaken at Turbo engineering in Thomastown. They have used their own chip which is a complete tuning system as opposed to a fuel rail or fuel pulse module. Ray spends some 4 hours on the dyno with each fitment adjusting both fuel and boost to ensure all the planets align with the additions and to ensure that things can’t be over-fueled (meaning more heat etc). Like most surgeons he has a somewhat paternalistic bedside manner but don’t let that put you off. He knows his stuff.

After the modifications, the immediately noticeable differences are;

-Wholly more responsive – It’s like driving a fully tuned petrol V8 (I kid you not, there is that much difference!)
-No flat spot when accelerating from standing start. Torque band is a lot wider and flatter . The vehicle just accelerates cleanly and powerfully.
-Much more acceleration on the highway. At 80 kph in 5th gear you can put the foot down and she climbs effortlessly upwards. Towing is going to be a dream as will dragging heavy loads up bloody high sand hills.
-It sounds a whole lot meaner at the back end with the 3 inch system and sports muffler (and this is important according to the crown prince!)


If this thing is tuned down, I’d be frightened to know what can be achieved with it bedded down and tuned right up. Quite simply these are the best mods I have ever made to a vehicle. If you were thinking of spending the dollars on this type of mod, do it but do your research and go to a recognised diesel expert. IMHO a simple plug and play fuel module is not what you want in your $70K, state of the art V8 diesel ute.


Throughout the first weeks of July, the new engine set-up has had a good 7000 km work out around some of our iconic outback tracks. The vehicle was fully loaded during this trip but not towing. The observations above stand. The vehicle accelerates like a whole different animal. On a long sharp gradient on the freeway just north of Melbourne, I used to be pulling down to 3rd to try and get up the thing. Speed was dropping below 80 kph. With the re-tuning, I was easily able to maintain 100-110 kph in 5th and only changed to 4th to drop a few degrees off the EGT gauge.

Fuel Economy has not been adversely affected and has remained more or less the same in both city and country driving. In the slower going on outback roads (average 60-80 kph with a fair bit of 4x4 for damp and slippery sections) the economy has actually improved by nearly one kilometre per Litre. This is a real bonus considering the abysmal economy figures in the first place. Where the mods come into their own is the solid increase in power when in a 4x4 situation. There’s no more having to put the boot into her to keep the momentum up in soft sand or mud. Easy manipulation of the accelerator ensures smooth, constant power in even a sudden, unexpected situation and that’s bloody great.


Dyno results; At 100 kph there is a torque increase of 150Nm (586 to 734 Nm) and a power increase of 21 Kw (80 to 101 kw). Average across the range of between 20-25% increase in power and torque. Original dyno showed that the vehicle was under fuelled and had very low boost settings. These increases are achieved with 33" tyres fitted.

Bugger you Mick O!

Now I want to chip & pipe my 78 series Military Dual Cab.

How much was the Taipan exhaust? I've looked around a bit & they seem to know what their doing.

I had an e-mail from a mate in Geelong & he reckons that he can get 200 RWKW & 1000nm of torque out of it by upgrading the turbo, pipe, injectors etc... for just under $10 000.

Alby, I'm at 65K or 45K since putting the chip in. No clutch issues. Did a front bearing retainer in the transfer case but I believe that was due to the bearing retainer cir-clip missing.


Jeff, that's some serious coin. Perhaps too much. I was less than half that for exhaust, chip and all the labour involved. Have made no move on the injectors as they are pricey to play with at better than a grand a pop. As I've said, I've had it tuned for a wide flat torque band to assist with towing. There's a lot more in it if I wanted to tweak it but I'm a firm believer in going for what suits you needs.

Members John Vic and Glenn own identical vehilces and have driven mine. Each would be able to vouch for the difference in performance and power.


Cheers Mick

Mick O,

Not really considering going down the larger Turbo route, but the Taipan exhaust looks good.

Jeff,

The Redback line of exhausts are pretty good too.

Maybe not as "refined" as the Taipan is, but they offer a choice of 3 mufflers (none:-)))' sports or 0.5 acre size), and all sections are available as spare parts.

I've got the latter size, not by choice, and it's not loud. :-(
