Thread: 4BD1 to 4BD1 T swap

As posted elsewhere by quite a few people, the 4BD1 is a strong engine that can handle turbocharging without a problem. So unless your engine has major issues then it is easier just to bung a turbo on the 4BD1.

IF you want to buy a 4BD1T, a perentie 6x6 engine would be a straight swap, all others would need the sump, bellhousing, filter assembly and a few other bits swapped over between engines.

Thanks Ben

I also found Chucaro's post from Dec 07 that is very informative

Thanks

I had a quiet day at work last Friday so phoned eight different Jap engine importers/Jap truck wreckers who advertised 4BD1T's for sale in the current issue of Deals on Wheels. Of the eight, only three had engines in stock. Prices for engines available ranged from $3750 to $6000 with three months warranty on all. Some were reconditioned, all were on an exchange basis only. These are all truck engines.

Of the five places who didn't have an engine in, two said they were awaiting more stock, one was closing down and two said they are very hard to come by. Prices here ranged from $4500 to $7000.

Thank You very much Bob
So you could say $ 6000 for a reco engine on an exchange basis plus labor to remove and refit if you're not doing it yourself
As previous post ; a sump and some other bits need swapping from the County 3.9 to the truck 3.9?
Again as per previous post , the prefered option then is to get a NA 3.9 County that has a good history and fit an after market turbo and intercooler?
Bugger , should have bought the Gembrook 3.9 that went for $ 7500 on ebay
And I know the seller

The truck sump has the advantage of leaving more room to run a decent size exhaust inside the chassis.

Definitely, the easiest way to get yourself a Turbo Isuzu County is to wack a turbo on an existing Isuzu County.

I'm shore this has been discussed alot before, our land rover parts man reckons that fitting a turbo to an N/A isuzu motor will shorten it's life, is this true??
We are planning on fitting a td5 turbo to ours sometime in the future, (we have the turbo etc)

Possibly, but the 4BD1 is a very strong motor that isn't stressed in a LR application. It may mean tou only get 950k km instead of 1 mil.

But if you run silly EGTs then you could kill it in a week.

I'ev been running "less than sensible" EGT's (that's one notch below silly) and haven't killed it in over a year and a half.
