Toyota 4runner fitting an ftermarket turbo. Will it explode?

Hi, I have been getting a little frustrated lately with the absolute lack of power that my Gen 1 2.4 litre diesel 4Runner can produce. Overtaking seems like it takes forever and going up hills even the truckies must be laughing. Towing? It's really outclassed.

I have been considering fitting a turbo to the current engine as the engine though gutless, has been well looked after all her life.The engine does have about 260000km's on her. Would I be risking too much fitting a turbo? Also, what sort of ball park figure could I expect to pay for an upgrade like this.

I would greatly appreciate any help I could get, especially from other 4runner past or present owners who have had a turbo engine.

These 2.4 's were imported into NZ in great quantities from Japan and were quite famous for breaking crankshafts.

Dont know if the Aussie ones are different but I wouldnt want to turbo one of the imported ones.

I have owned a forerunner for the last 10 years, it had a turbo fitted (Safari) at about 180000kms, still going at almost 500,000kms.

They will never be as fast as the new electronic flashy 4wd's, my only issue with mine is the towing aspect and having a moaning wife.

With none of the above the old bus is fine, will sit on 110 all day, might slow a touch on the hills but if you are not dragging 1.5ts no issues.

However. unless you plan to keep your bus for years to come then financially it will not be worth it, the turbo would cost around 2000 fitted, you might get away cheaper if you can find someone.

Aa for risking it, you would have to be fully aware of the condition of the engine, does it blow smoke, does it start easily, any oil leaks, would suggest you have a look at the injectors and air cleaner etc first to see if that might help first.

The cost of the turbo in my opinion would be prohibitive, given the value of your bus.

You would be better off puting the money on something newer. I found an 95 3.2 v6 ls Jack(130kw) for my son with 130ks on it for $5000. It also come with b/bar t/bar air ps even p/w. The little buggar decided the mag wheels on it where to old hat so I let it slid. But if anyone wants a good cheap 4wd I have the owners ph no still.

Brer fox.
You say you "have been getting frustrated lately" by the lack of...etc.
Does this mean that the performance has dropped recently?
If this is the case it would indicate "tiredness" of the engine, something that fitting a turbo now could be a death warrent unless the "tiredness" problems are rectified beforehand.
I would first off be looking at a compression test, injectors and particularly injection timing.
Very few realise that a couple of thou. wear on each gear in the train ( I think 3 in your case) to the injection pump can retard the timing by several degrees.

As Mike said have you had the injectors done and pump checked. Normally done at about 200000ks. If this has been done extractors and a larger free flowing exhaust will give you some extra power with out over stressing your engine.
