Jeep 4.0 engine.

Just wondering if it has been done or if it is possible to fit the AMC 242 (Jeep 4.0 straight-6) engine into a Defender. Can bell housings be modified and such?

Just seems to be a stronger lump than a Rover V8 being cast iron and puts out similar power as 3.9 V8. Arround 180bhp.

Most things are possible with Landys, and I'm sure that if you have a good look around on Google for 'Jeep engine into Land Rover' for example, there will be some nutters who have done it. You may find that you'll have to make a "conversion plate" in order for the engine to mate with the gearbox and there's no doubt that you'll need to make modifications to the chassis and possibly the bulkhead, so I wouldn't expect it to be a simple swap, but certainly nothing too dazing if you're mechanically / engineeringly minded.

One question though, why go for a Jeep straight six? I really can't see the sense in it. First off it's a Jeep, and they're **** , secondly it's just a boring "quiet" engine compared to something like a Cummins straight 6 diesel, or a Detroit V8 Diesel. It'd certainly be a lot cheaper to run, easier to maintain and it'll sound a hell of a lot better too if you dropped a 6 litre or a v8 diesel in there. It'll shift some too. Here's an example of one that's local to me:

Mainly for it being more reliable that a RV8, more powerfull than a 200TDI and not having to worrying about upgrading the rest of the drive train as you would with a big 6 liter diesel.

And the Jeep engines are easy to come by.

I do like the sound of that big diesel though!

Fair enough I'd always go for a diesel over a petrol, but each to his own. Put it this way, what you want to do CAN be done, providing the engine will physically fit between the radiator panel and the bulkhead. It'd just be a matter of getting down to the nitty gritty of modifying the chassis, the bulkhead (possibly) and then making various mounts, brackets, plates etc, pipe works, exhausts, cables and wires. You'd be taking on a pretty mammoth task but if you're happy to get your hands dirty you'd do it. What you'd end up with though is a Land Rover Jeep, and you'd get no sympathy from anyone

If you do get one put it on gas, they like the petrol as much as the V8

The Jeep 4.0 six pot was not renowned for being a good engine. Many of them suffered with head warping problems leading to head repeated gasket failures even after skimming. Probably why they dont make that lump anymore. The 4.0 Cherokee that I used to own only did 16mpg if you drove it like a Doris but when you got your boot down it was nearer to 12mpg. It was not a bad motor as such but there are better engine options out there such as Isuzu.

If you want a powerful reliable V8 then get hold of a 350 cubic inch (5.7 litre) small block Chevy engine. Its about the same physical size as the Rover engine and you can get shed loads of bolt on goodies.

pos that sound's amazing'i want one in me disco

Why dis the rv8 so quick?such a basic engine rhat has been around for years and easily tunable with specialists in this country,won't knock value off like some engines will as well.

possibly because it's torque not pure bhp.
try a haybusa engine in a landy=crap but great bhp

yep decent range of rv8 cams as well....

It's not mine, but it's bloody brilliant. The guy who has it is local. He's got a couple more videos of it too, one of which he is giving it some - sounds superb
