4bt or 6bt into GU patrol

[vet 180]

Got an American mate here with a TB45 shorty GU patrol. Manual, 2 inch lift and 35’s. He drives from Dubai to Abu Dhabi daily and it’s been a great reliable car.

He would like to take back to the states one day, but it won’t go back with the TB45 in it or at least it won’t stay in there long. A TD42 is an option, but then he is doing a conversion (although factory optioned) for an engine that was never available in America. Makes it hard to service and maintain. A Cummins makes more sense as parts are available etc.

So what is the current hotness in Cummins to patrol conversion kits?

Cummins ISF? http://www.fourwheeler.com/how-to/en...n-tj-wrangler/

A 6bt in a shorty would be like one of those nose heavy clown cars that can stand on it's nose and slowly tip back again

A modern 2.8 won’t interest him. He wants old school no ecu and displacement. I know the 6bt is heavy but a 4bt isn’t too bad and it’s not like the 4.5 is light

4BD1T, or what ever the current version is? Stock motor is good for 50 psi apparently before you need to replace the head bolts. Enough Yank support?

LS3.

He is not interested in LS3. He would actually prefer a SBC.

4BT he would be happy with

4HK or 4JJ.

Not a lot of Isuzu in the states

More than you would think. But most N series run the V8 petrol or CNG engines.

Cummins ISB4.5 is the only engine you would want to fit, 160kW/850Nm is pretty stout for a 4WD - but its a modern engine.
But if he wants a mechanical engine then there is always the mechanical version, it just wont be amazing.

Yeah he want a mechanical engine. He is very willing to sacrifice power for it

I actually agree with cracka and think he should go LS. Turbo 5.3 iron block would be my pick. Maybe I will try more to convince him...

the yanks got these in n series trucks with auto. the auto is the jatco 4re03a (?) that the patrols got. it might be doable with a bellhousing swap. in the states, it's probably still possible to find a 4bt with a sbf or sbc adaptor and just use a conversion bellhousing onto the manual that's in it. the sump will likely be rear bowl too, which will probably help with diff clearance.

he may have to choose carefully which gearbox to use too. some were 0.85:1 5th, and some were 0.73. the taller ratio is better of course, and i think the petrols are geared taller (3.9:1?) which would be fine with 35's.

4bt moved my f100 along pretty well. sure, it was no duramax, but it pulled all sorts of shit and when empty or lightly loaded it was rare to have to pull it out of top gear. all while returning mid 9's/100.

also, i'm with dnegative about the isb4.5. they're pretty awesome. people spaz out over electronics, but they're fairly reliable these days as long as they're fed with clean fuel. if you shit the injector pump in a mechanical engine, you're just as fucked as if the ecu died.

Tried automotive etcellence or aussie cummins imports on faceballs? Pretty sure they should be able to get all the gear required to make it happen. Even better being over there, your mate probably wont have to deal with asbestos bullshit?
