Don’t think so, no hair up there and I don’t wave the hair down there. Though it may get the occasional blow but that’s from a nurse and not a hair dresser

[QUOTE=isuzurover;1763064]The ones that have "3.9 DIESEL" on the doors are a dead giveaway

The 3.6 [4BE1] is also not a bad motor.

/QUOTE]

I have my eye on the 4JG2-T as well.

I assume the 4HG1-T is a bit overkill?

The 2 for an isuzu denotes INdirect injection. Not as efficient, and heads are not as strong. 4JG2 engines have been known to have head issues. I would prefer a 4JB1 instead.

The 4H series of engines are great, however the only problem is that the engine is "reversed" - the timing gears are at the back, and all the usual gear driven ancillaries are at the back of the engine. Makes like much easier for servicing in a cabover of FC vehicle, but in a normal landie you would need a huge hole in the firewall and it would be a PITA to service. The early models also had a different gear tooth size and were prone to stripping IP (or PS ?) pump drive gears.

Thanks mate, some great info there.

So the 2.8 4JB1T is a better option?
I can get those over here as low kilo imports for around $2200.

4BD1's are unfortunately scarce over here.

You see Isuzu trucks with their cabs beat up, in backyards around here from time to time.

Now not that I would do anything like changing my 300TDi for a 4BD1t, or would I?

Easy..

if you can hear the engine running but cant seem to get the truck to come into focus, its probably got a suzi in it

Yes - I would fit the 2.8L 4JB1T over a 3.1L 4JG2T. Others may disagree. We did work out that it should be possible to fit a DI head and pistons to a 4JG engine, but a lot of work...

Just make sure you get an industrial/truck 4JB with timing gears, not a timing belt - they came with both options.
