Thanks JK

So from the looks of it the stock computer can supply enough fuel to run about 9-10psi.

can anyone confirm this?

Also how far will the injectors go before they need to be upgraded?

Also the pistons, rings and valves, can they handle 9-10psi??

This engine that will be having the turbo added to is a little warn 280k odd and is pumping out alot of smoke?

should the turbo be added still?

Also do the heat lamps need to be updated at anystage?

sorry for all the questions

Hello Joe,
I got my 80 Series (with 154,000 km on the clock) done in March 2005. It was done by AXT Turbo's in Cheltenham Rd Dandenong. If you need to know their contact details then let me know. I was happy with the job they did and they were very close to the price quoted by ARB Southern, also in Dandenong. I chose AXT because they took the time to sit down and explain the whole process in detail to a dim wit like me to a greater extent than anyone else I spoke to. I'm sure ARB and many other would do as good a job, I just happened to like the people at AXT.
It is a Garrett Turbo and the cost was $3400 all up including labour. Add $230 for a Turbo timer.

I did not need to get the compression changed. I got that line of thinking from one company in Pakenham but everyone else I spoke to at the time said it was not necessary.

I can't say I had power problems in the pre turbo days it was just the normal diesel slow down on hills and so on. The effect of the turbo on the truck is significant but don't expect too much difference down below about 1500rpm. After that it has heaps more power. I don't know what effect putting a bigger diameter exhaust system would have but I've heard so many different stories that I've decided not to bother as yet. The fuel consumption is slightly increased (From 12 Litres/100km to 13 litres/100km).

I hope this helps. Just ask any questions you like and I'll get back to you.

Tom

Thanks for all the input guys

i am just curious what turboglide and the other companies actually changed in regards to the internals of the engine, because, the car is smoking a fair bit at the moment, althought the extractors and exhaust may have a bit to do with it, but there is a fair amount of smoke.

i dont suppose anyone out there has a receipt or quote or anything they could e-mail just so i know what has been done??

also what psi is everyone running?

Cheers

Joe

I would only fit an AXT turbo kit as they are very good quality the people who are going to fit the kit should give your 4x4 a compression test first to see if the motor has good enough compression.If it hasn't you will need to rebuild the motor then fit the turbo.

Turbo a 1HZ diesel

A number of turbocharger kits are available for the 1HZ. With an emphasis on reliability and engine longevity and driveability, the fitting of a Turbo kit gives a healthy 30% - 40% power and torque increase.

It is important however to be somewhat conservative with this motor when it comes to extracting lots of power. While the bottom end is very robust there are structural issues in the head (especially around the pre-combustion chambers) that dictate how much power can be extracted reliably. Whilst there is no doubt a good degree of over design is incorporated in the 1HZ, adding a turbocharger will stress the motor further and bring the performance envelope that bit closer to the limit so a maximum boost of about 9 PSI is recommended.

Things like the condition of the injectors and injector pump adjustment can have a significant effect on longevity. Hence the importance of a well engineered unit that is installed by professionals who are experienced in this field.

There are many examples of turbocharged 1HZ's with over 250,000km on them and running strong. There are also a small number of people in our group with bad experiences through mainly trying to over fuel, over boost and/or lack of injector/pump maintenance. The feeling amoungst most in the group is that a boost compensator is a worth while addition to avoid overfueling at low rpm/low boost. A boost compensator allows the pump to be adjusted leaner for low boost conditions and increases the injected volume under high boost. This results in better economy and drastically reduces the amount of exhaust smoke.
