2003 td4.2 patrol

Go the whole hog, Turbo dump pipe and the 3" exhaust plus a full tune up on a dyno.
Exy but worth the effort.

did u find the motsons upgrade good?at present i get 5kms per liter of fuel, does the upgrade improve this.thanks

HI there , had the car been "gutless" since you got it ?? or its been a slow progression downhill ??

turbo and exhaust mod will make a HUGE difference , but just remember these diesel as are not the same as petrol motors.

The exhaust mod is useless without the turbo mod and the turbo mod is useless without the exhaust.

Turbo mod,dump pipe,exhaust and dyno tune and youll love it.Dont do half a job on these TD42's .

I agree with one poster, that 5k's per litre is woeful from this car, should be closer to 7 so there could well be a problem causing lack of power at the same time???

I personally would start with the lowest common demoninator in a major power upgrade and keep adding bits toward this major upgrade until you are happy. 3" exhaust and dump pipe will be a great start and necessary for any further mods anyway so do this and see what you think.

Where are you, if in Brissy I can point you in the right direction to good outlets to get the most of what you already have.

Cheers, Trevor.

Hey Timbo2,

I've now got a 99 TD42T (Non intercooled). Ours was running like a slug since we got it, but didn't really realise as it was the first patrol we'd owned. Wife pulled up beside our twin a few weeks back (well it looked identical to ours) and when the lights went green, the wife was left at the lights as if she hadn't accelerated at all.

So we got ours tuned a bit, had the turbo boost adjusted and the injectors cleaned and adjusted (not completely replaced yet though) and it has made a very noticeble difference in acceleration and general driving.

I'd suggest before you go spendimg thousands on turbo mods etc, get it looked at by a diesel mechanic as your injectors might need replaceing or adjusting along with fuel pump and turbo boost setting.

Yes, I'll be getting a 3" pipe installed and injectors repalced in the next 12mnths, but the $350 spent on small adjustments has been well worth it.

Ummm, at the risk of stating the obvious, have you checked your air filter lately?? If it's gutless and using too much fuel, that's the first place I'd look...

Also, some (but apparently not all) TD42's have a gauze strainer in the fuel pump (under the inlet pipe banjo bolt).. doesn't take much gunk in there to restrict fuel flow, and that'll make it pretty gutless also.. take this out (if fitted) and blow it out with compressed air (don't lose the spring!)... Might like to change your (main) fuel filter while you're at it;-)

Check the simple things first, I say;-))

can definately recommend Beaudesert exhausts for a 3" system. only problem is they don't open on saturdays (unless that has changed in the last 5 months), so it will need to be a mid week day trip for you.
i was abit disappointed with my turbo add on to my 1HZ cruiser, didn't have the power i expected (was still running factory system for a couple of days). that was until the 3" exhaust system was done, made a huge difference to the vehicle.
they are about $300 dearer then other places that do 3" systems, but i reckon they're worth it. the place is by no means a small country town workshop, it's bigger then most brisbane exhaust shops and has some pretty impressive machinery there aswell.

It might pay to check the gauze filter at the banjo bolt on the fuel pump if the filter is dirty it will cause a loss of performance

timbo, give MTQ in Toowoomba a ring, talk to them about turbo mods etc, they know there stuff. More than happy, have driven from Victoria twice to have them mod my Nissan.

My opinion is you can have a 4.2 that is a slug but will go for ever or a 3.0 which goes like a shower of s*&t but will not last very long. I know what I would have.

Hi Timbo2
Just wondering, how have you driven the vehicle whilst you've had it? I'm a big believer in running engines in properly. Our 2004 4.24td Patrol was and still is a slug, but getting better. Mind you, I'm used to driving a V6 Camry...
The Patrol had done 40,000kms when we got it about 12 mths ago, and couldn't beat a snail off at the lights. AFter driving it like a racing car all the time, it's on the improve. Still not as good as the Camry, of course, but I'm getting used to it....
Drive it gentle, and it will be gutless; run it in hard and it will be a good vehicle!
