Hi guys, have followed the threads you and others posted on powering up your turbo diesel 4.2 patrol. Seems to be a big range in prices from just under $2K to close to $3K. Cost obviously increases with the work done. Two K gets you exhaust, extra boost and re-tune which is what Chris M has done (now with new dump pipe). Three K gets you the same but with turbo mods as well. Some places are charging $2.5K for similar work but you'd need to see what you actually get.

I've also noticed increased figures are quite different. The guys charging $2.5k to $3k are generally quoting about a 20-25% increase. But based on Chris M's dyno graph the increases from Brisy Tuning and Turbo is close to 70%.

Chris have you checked into this further, not saying they are wrong but this increase is huge and with less work done???? Sevo's latest report on his vehicle shows similar work but with a 30-40% increase. Either way both increases are well over what MTQ, Motson's and Superiour Turbos are quoting with more work and more cost.

Anyone got some answers??

Dear Austravel

We recommend that you tread carefully and be sure to understand exactly what you are getting for the cost.
For $2600(inc) at Denco you would get complete replacement turbo, dump pipe and 2 1/2" mandrel bent exhaust, the larger free flow crossover pipe and dyno tested before and after.
Remember:
Not at what cost but at what value?

Gday Austravel,
As you have seen by my previous posts i have completed the power up on my vehicle,as far as costs go i did it cheaper because i did it myself and im in the trade so my prices on the parts needed are far from retail.
My first run on dyno was with only 1600km on clock and produced 101bhp and 217ftlb this was with a 3inch exhaust (dyno was not available before i fitted exhaust) . Then i continued with mods and fitted boost controller , upgraded dump pipe, and boost compensator adjustments , please note standard turbo is still used. Final dyno run produced 129bhp and 306ftlbs with 12psi boost. I have a in cab pyro and boost gauge fitted to monitor this. Temp rarely sees 450c for any lenght of time.
My pump timing remains standard on my TD6 , but on your vehicle is is common to run .75mm plunger lift. As mine is already electronically accurate no gain is made if i run my timing other than standard.
Question for paul , Have you guys completed a power up on a TD6 ? if so what sort of gain did you get?
Cheers
Sevo

So based on what you've done it seems a bit of a waste to be modifying or changing the existing turbo????

Any chance I can email you or ring you to get some further advice???

Thanks

Gday Austravel,

Sorry I haven't replied earlier, but I've changed jobs and have been unable to get to the computer very often.

Mate, all I can say is that John is a very reputable operator. You see above that Sevo only hits around 450 degrees, mine will climb to 600 degrees when under heavy load. I've been told to limit temps to that for turbo longevity.

I've done 18,000 k's since August so I've well and truly had a chance to test it out.

I had a proper run against a 3L ditronic'd powered up patrol running all the same mechanical mods. The 3L doesn't have the torque. I pulled away in 3rd gear. Can't feel the camper on the back.

Gets 8.1 K's the L on average, 50 city/50 highway. Economy drops to around 7.2 when offroad. You've seen the dyno, that's all I have.

It gets up and boogies, easy to drive, and alot of fun! When you end up around town here, take it for a blast, I'm sure you'll be duly impressed.

I've heard of another mod which requires replacing the manifold. Apparently a further 10-20% increase.

Cheers,

Chris.

Thanks Chris, sounds like you've got all the grunt you need. Is the pyro before or after the turbo??

After as far as I'm aware. That's why it gets the higher temps.

Good luck!

Thanks Chris, you might want to just confirm where the pyro is mounted because if it's after the turbo it will be cooler than before. If you getting 600 deg C after the turbo it could be well into 7 hundred's before which is pretty high.
Regards.
