Thread: 4Bd1 differences

Forgot to add it has had an aftermarket turbo fitted. Is turbo kits ok for these engines. Are there factory turbo Isuzu engines that run piston sqirters ect

Plenty of threads out there on this but quick answer...
Plenty of people have done conversions and most are just as good as factory as most that take on the task know what they are doing...
Turbo kits for these motors are quite rare in my books as I have never seen one....
Nothing wrong with these motors being turboed and I would say are probably the strongest motor of its size in the world...
Factory turbo motors have some differences but easier for you to do a search...

The easiest way to tell a factory turbo motor from an aftermarket turbo motor is the oil drain. The factory T motors have a cast in hole near the bottom of the dip-stick where the drain-pipe bolts on. Non turbo engines have a cast rib through here instead so the turbo drain will be somewhere else.

Yes the factory turbo motors have piston squirters. But I'm not aware of anyone melting a piston with an aftermarket turbo, so it's not a real concern.

I am a bit unfamilar with county and Isuzu stuff, so sounds like I shouldnt have to be to concerned, its got a 5 speed behind it to, so i think its a defender box

thanks again

If reverse is below 5th, it should be fine for a good while (or a long time depending on box and how it is driven), if reverse is beside 1st, then it won't last.
