Can anybody tell me how often the injectors on my 2001 100 series diesel with DTS turbo fitted should be serviced (Nozzles etc)?

I was speaking to a mechanic who told me that the 100 series injectors should be service every 30000-40000km. He also said that if they haven't been regularly serviced I am risking damage to my engine due to insufficient injector performance.

Can anybody tell me what the best exhaust system is for my vehicle 2.5 or 3 inch mandrel bent and any recommendations for this to be done in the Brisbane area?

How much do you think this exhaust would cost? I have been quoted anywhere between $600 and $1100 for a maild stell 3 inch mandrel bent system including a new dump pipe.

Thanks 100 series

The guys at Cooma Diesel told me every 80,000 k's for injectors and fuel pump service, even with an after market turbo fitted. Give them a call, they are very helpful. 02 6280 0178 or Cooma Diesel They often have people driving down from QLD for a service.

As for the exhaust, I have no idea. It was discussed on LCOOL yesterday, was this your post? I can't imagine there being much difference between a 2.5 and 3 inch exhaust system, if the bigger one is just as cheap why not go for that as it will definitely have lower back pressure.

I was told 80 to 100, 000 also not 300. Sounds a bit long between service for me.

Had mine done at 105,000 after i bought the vehicle. Had a Turbo fitted at 135,000 and had them checked, all fine. had them checked again at 165,000 and still all good. my thoughts have always been 80 to 100,000 k's is about where it's at.
I had a three inch mandrel bent fitted with the turbo, it seems to breathe a little better, but sounds like a mack truck when it's working hard.not loud in the car but just deep outside. (personally i love it) cost $825 and they did an excellent job.
mate has a 2 and a half, and it feels a bit restricted. a lot comes down to the muffelers and bends that are fitted as well.

You should get well in excess of 200,000km out of your injectors and the life of the engine out of the fuel pump, dont let some money grubing mechanic try and scare you into changing them out, I've been supervising a fleet of Cruisers and Patrols etc. for 15 years and prior to that working on them, and I have learnt to keep the original equipment in place for as long as possible as as soon as you start putting rebuilt components in you end up having problems with poor workmanship, to the extent I will only replace a single injector with a new injector if 1 has failed.
As for the exhaust I would sugest the 3" in stainless steel, the mild steel may only last 4-5 years.

I am currently considering fitting an after market turbo to my 100 series diesel, I'd be interested in any feedback about the problems etc that have been experienced after fitting one.

Also interested in the impact on the fuel consumption.
