Diesel tuning specialist in Sydney

Hey all,

I've just had the engine in my 1HZ troopy rebuilt as well as the injector pump and reco injectors.

It has the DTS turbo kit with intercooler. I've also got the injectors rebuilt with higher cracking pressure for turbo applications.

We will be shipping the car overseas for a round the world expedition. Some of this driving will be in altitudes over 4000m, the pamir mountain range in Central Asia for example.

I'm looking for a reputable diesel tuner with dyno that can get the mixtures right for my setup and our intended destinations.

It's running stock boost, whatever the DTS turbos waste gate is set at, I have a boost gauge and pyrometer which I will fit. I have also rebuilt the engine with AE pistons which are much stronger than OEM due to the extra strain from the turbo.

The bloke at the APA Diesels Yenoora that rebuilt the diesel pump said he knew where to set it to suit turbo applications and that it would not need further tuning. Although I'm sure he has a lot of experience I still want to get it 100% right on a dyno before we set off.

A lil off topic here but what are these 1HZ motors like performance wise, I know it's like a truck and can not compare to today's common rail diesels. But even with the turbo, on the F3 (if your familiar) the two big hills after Orimba and the Mooney Mooney bridge it only manages about 60km flat chat full boost, empty car. I never drove it before the rebuild so can not compare and was thinking (hoping) maybe the diesel pump isnt providing enough fuel hence the lack of performance. (It's fitted with an 80 series LC auto as I'm paraplegic and can only drive auto, so that may be sucking power.)

Thanks.
