I am curious if these type of turbo's last long, or if they have weak points.
What if you put an intercooler behind it?
Is a Garret T25 better?

They appear to be a very solid and reliable turbo. Mine was only retired due to dust erosion, it has survived oil starvation twice without any problems. I went to the T25 simply for parts availability, if the IHI was still in good condition I'd be perfectly happy using it.
The IHI is good to ~30psi according to the charts. It has 60mm wheels and can deliver higher pressures than the T25's.

Hi,
An update....
I adapted my transfer box to a 1.003.
Now the Landy drives faster than that I dare to drive it (>140 Km/h according to the navigation system).
This is cool.

Really Cool was that a Discovery 2 TD5 could't beat me in a traffic light sprint. The second time he really tried hard, but my old diesel was faster, despite from the 1.003. Isuzu rules!

Good to hear your giving the modern technology a run for its money Takel!

I bet that put a smile on your face!

Help, I was going on holiday, my caravan behind my Landy, and then the Turbo made a skweaking noise, and black smoke and no power...........
I had to hook off the caravan, and drive back to my home, where I took our ever reliable Swedish friend, the Saab 900.

However, my IHI turbo from my 4BD1T now is broken, and until now, I couldnot find a new turbo, or a rebuild one.

Does somebody know a good shop, or does somebody still have parts for my old turbo?
The bearings are worn, and the rest needs to be checked.

Parts for IHI RHB6 are almost impossible to find, it is an old turbo that was used on very few applications.

You can buy a chinese parts, a complete chinese copy or you can adapt to fit a more common turbo.

Complete turbo off ebay, but non-wastegated housing. I don't know if the turbines are the same size or the housings swappable:Turbocharger ISUZU 4BD1T IHI RHB6 CI53 Hitachi EX120 | eBay

Mellett have some parts too.

As Dougal posted. Alternately Takel, there are plenty of turbos which can easily be adapted to fit. E.g. the turbo from a saab 900T (classic) would be about the right size!
