Hi, I am looking at purchasing a 1998 100 series cruiser 4.2 diesel 1 HZ auto fitted since new with an aftermarket turbo, done 150,000 kms. Can anyone tell me if fitting a turbo to this engine can cause problems for its longevity & if so what are they? What sought of life can I expect from this engine if serviced every 5000 kms. I have read various threads on the subject mostly positive and a link that talks about engine failures due to the higher temperatures created by the turbo. Anybody got one fitted with an aftermarket turbo that has done high Kms. Heavy towing will also be involved (23ft boat).

What sort of money are you paying for the cruiser?

Only reason I ask, I am thinking of selling mine soon - it is fairly similar, but I don't know what sort of money to ask.

If you don't want to say, it's cool - I understand.

Hi Ian,

I have a near identical vehicle - 98 100 series, Stadnard Model. I purchased it with 110,000 km on the clock and immediately had a Schwitzer turbo installed by ATS Turbos. I've got 163,000 on the clock now, and haven't had any problems at all. Makes driving the sleepy old 1HZ a lot more pleasant - particularly when towing (we tow a 2 horse float, which when loaded probably comes close to your boat weight).

When I installed it I was told to be religous about oil changes every 5,000 km, which I have been. I also had the boost set conservatively at 9 psi (some people push it up to around 12, but that puts a lot more load on the motor, and I didn't wan't the risk).

Hi Ian,

I have a 1991 80 series landcruiser with a 1hz that has had a Mike Vine Turbo fitted since brand new. It now has 300,000km on the clock. The engine and turbo have never been touched and it does not use one drop of oil between changes. It has spent most of it's life under heavy towing conditions with 2 or 3 regular trips each year to NT and now I mostly use it for towing my 23ft Trailer Sailer which weighs approx 2700kg loaded.
It has been serviced every 5000km and I have always used synthetic oil. For several years I have been using Cruiser Oil made by Synforce in Hervey Bay. Excellent Oil!!!
I think regular servicing with good oil, a first class cooling system (don't let it ever get hot), and don't have the boost set too high on the turbo (<8psi) and you should be able to expect many trouble free years.

I would suggest though that as yours is an auto, which can generate more engine heat than a manual, that you renew your entire cooling system with new components from day one with large core radiator etc. and also add some additional cooling measures as I have by fitting an oil cooler for the turbo down behind the winch slot in the bullbar etc. I would also fit a seperate transmission cooler.
It may seem like overkill initially but if you have plans of going north or west then the intial outlay before you travel is much more cost effective than trying to solve the issue on the side of the road when you are a long way from home.

Good luck with your decision.
