I've decided to go for a brand new 2005GU 4.2TDi ST-S and was wandering what my options are to get more power and torque out of the 4.2TDi. I live in Melbourne so can anyone recommend where to go and also approximate costs for these mods.

Cheers

I had a powerup done to a the TD6. I obtained 155hp at the rears and spent $1,800.00. That included blanking off the EGR, adjustable wastegate, 12psi boost, injector upgrade, 3 inch mandrell bent system, 3 inch dump pipe, no muffler. Pre and Post dyno. Make sure you get someone who knows there stuff. Had a mate who had the same stuff done, ran higher EGT's with more boost and worse result ie. less hp. This was done in QLD. There is actually someone on this site who is and already has driven up to QLD from Victoria to use the same guy.

Cheers.

do these changes effect warranty and also does this person (the one that drove up from Victoria) have to drive back up if something stuffs up on those mods?

Tiger,

Your talking very simple mods. But anything you do it most likely will void your warranty. Suspension, tyres, rims, if it's not factory, you will have problems with Nissan. Nothing should stuff up in those mods as theres nothing really to stuff up. Blanking off the EGR just kills the environment quicker (sorry greenies).

I had no doubt that my mods would do my clutch in. But in all honesty and in my own opinion, the TD42 is one of the toughest motors. They only kill them running 18-20 psi with big fuel pouring in. Overfueling them can cause problems. I've used the same mob twice now without a problem. He will only run a max of 12psi unless otherwise requested.

I did 25000 k's or so on the powerup. It ran beautifully. Browny (anor member on this site) purchased the vehicle. Have a chat to him and see what he thinks. I also did 120,000 in the GQ with exactly the same work.

I should have my dynos laying around somewhere from both trucks. I can shoot them to you at some stage.

Cheers

Chris.

Tiger,

Can vouch for Chris's info a top motor to do some "basic" mods too, much more driver friendly. Obviously the waranty thing is an issue, but as Chris has mentioned a very tuff motor the 4.2 oiler, and as long as you don't go silly with the boost I reckon the motor actually runs and breaths better than from the factory.

P.S. You can get me at davidbrown at myaccess dot com dot au if you wan't to have a drive of mine and see what you think.

Agree with you truckster. Ours is planned to go there when it's out of warranty and have seen their work and dyno figures on other vehicles. Pretty impressive stuff!

Hey Tiger Tough, congratulation on your new Patrol, I bought mine about 2 weeks ago, I posted the same questions regarding the power up and got the same responses, these guys really have the answers its good to get honest advice. I was worried about the warranty issues as well so im going to settle on maybee just the exhaust for now and worry about the rest after the warranty expires, besides theres plenty of power there for me for the next 3 yrs, plus it will give the engine a bit of time to run in....(just my thoughts) Have you or are you getting any other mods done, susp, tyres etc.?

Regards,

Babs

Hi Tiger,
Why stuff around with a 4.2 and aftermarket "fixes" when a 4.8 petrol is going to flog it anyway. With extra service cost and initial purchese price, not to mention fuel costs I have a small problem with the deisel dilema? I have had 4 petrol patrols with approx 950,000klm's and have yet to have a significant problem. Check the archives on blown motors and overheating problems with nissan diesels and sleep on the results. My opinion only andf hope you are happy with your new truck.

Yeah i was thinking the same thing Rob about going petrol but what about milleage from the tank?? How much do you get out of a tank in the bush with aircon running at the same time?

ps. thanks for all your replies everyone

Tiger,
I too agree with truckster about Denco at Wagga, but I will add that s@fari did no favours for me when I had their intercooler and stage 1 upgrade done on my new 00 4.2 turbo gu. It ran extremely hot most of the time but they did nothing to help stop or cure the problem. Just recently had MTQ do a stage 2 power up and that has actually helped the overheating (non to talk of in 20 000 km)since this job. Power from this setup is not what I would call SESATIONAL but it is good, whereas the torque is SENSATIONAL. I'm sure I'm driving an auto now, it just stays in 4th all day even on big climbs. Job was done at their Toowoomba branch but I think MTQ have outlets or distributors all over for their warranty work but I have not needed to test that side of things. You will stuff the warranty by doing this but I had heaps of problems re nissan warranty so I think it is not worth the paper it is written on anyway. Hope this is of some help.
Regards Trevor.

Tiger,
my patrol gives approximately 6 ltrs/100klm on bitumen without full length steel roof rack (5,5with rack) this drops to around 4 off road hard driving with air. I have installed a long range tank, 159ltrs, which allows me to fill up when the price is at its lowest and just top up other times.

So what your saying is it does about 20L/100km in city and 18L/100km offroad. What figures do you get when towing?

ps. I took average for 4.2TDi at 14L/100km and added what you claim or have I misread something?

Tiger, sorry I meant 5klm/litre on road. Don't know about towing, the shock factor is too great, so I don't keep track that much. I tow a 18' Jayco van and the pick up for overtaking is awesome, so I guess it's either fuel economy or performance. I have considered going to the dark side (diesel) but as yet have not been convinced of any benefit beside fuel economy and the extra servicing costs, down time and initial purchase price make a pretty big dent in the savings .
