I know this subject has been beat to death, but I have 2 dilemmas. I have a 65 109 ready for a new engine. Brand new galvanised military frame, sals rear axle, galv bulkhead and breakfast and mostly new body panels. I want to use it for camping, hunting and daily driver. It will need to go about 75 mph and be able to hold hill speed and tow lightly. Am open to gas or diesel. Also have a 71 military p/u with sl. modified 2.25 and a crappy rebuilt tranny which shakes and pops out of 3rd. And to add to that, my Fairey O/D has about bit the dust. What to do? What to do?

Well unless you want to ruin your galvy or redo it I think you can rule out the small block V8 conversions as they require some modification. If you want to kep the galvy on your frame and not change the engine mounts your choices are limited.
From memory you a 200 TDi will dropstraight in with some interesting intake/exhaust routing but it has an open timing belt cover. A defender unit will also fit but requires altered engine mounts. I think they would get you up to speed but you'd need to ask someone who's got one.
There's also a following for the Mercedes and cummins diesels that you will need to consult others on as I am no expert.
Then there is the traditional route of the Rover V8 but again I think it needs bulkhead mods. The Rover V8 does open up the option of using an LT95 (You need CV's up front then) for something akin to a Stage 1 set up.
A couple of us are looking at the old school route of putting in straight sixes. Both the Chevy 250/292 and the Ford 300 are good engines with a very loyal following in world of light trucks and drag racing. There are some interesting things like fuel injection or some wild speed bolt ons to get you that 300hp.
With any of these you have to consider your engine weight vs gearing vs the torque and power curves vs the strength of the series drive train.
I've just bought a 109SW with a Chevy 292 on a Scotty's adapter to the series box. Even although it seems to have lasted a decade or two in this guise I am a little concerned about longevity. In this case I am looking into sourcing a GM bellhousing & clutch to mount an NP435 on an adapter to the series transfer case. I don't think it will be cheap and the purists will no doubt hate it but it should be bomb proof.
TeriAnn will no doubt be along soon with some useful advice from her website.
Food for thought.
Cheers

The only thing I would add is that even with a swap to a fulltime T case- LT95, or LT230 you don't necessarily NEED CVs, it is nice but look at all the US trucks that used the NP203 transfer case for example... They lacked CV jointed front axles and did ok. Also it is possible to convert the LT230 or LT95 to part time 4wd.Comment

Before you get too excited this is not even close to accurate.Originally posted by greenmeanieComment

Right. Only one of the two chassis mounts will line up. It also depends what the 200 Tdi came from. An ex Defender 200Tdi Turbo and ex-Disco 200 Tdi turbo mount completely differently. Open timing belt? What's that mean?Originally posted by junkyddog11Comment

True true. But here is something that may do what you want. From our good friends in the UK.Originally posted by junkyddog11

p.s. Check out seriestrek.com for an interesting Mercedes turbo diesel in a 109 project.

Lost part of the sentence. I understand that the 200TDi from a Sherpa van is different from the LR units. The mounts line up but the manifolds are an issue and it has an open timing belt cover which gives the belt less protection if you plan on playing in the mud. The LR units have better manifold routing but the mounts require modification.
Take a poke around some of the LR UK forums for a more complete description.

There are several great threads on the Series 2 Club forum about reto fitting a 200 TDi in a series. Looks like a complete pain in the ass for someone as un-talented as myself in the Fab area.
Interestingly, some folks forgo the turbo altogether...
Cummins if we're dreaming. That 4Bt that Tim Cooper built looked very nice indeed. . .Comment

Was that 6BT then? All I remember is that Cooper put a cummins in a 109. . .Comment

Probably a 6AT, he is a 6AT fanboy. There are a few 6AT powered rovers floating around.Comment

It's the one for sale on and off again on Pirate? Cool Truck. Wish I had that kind of money/space laying around...Comment

I donno which one you mean, theres a lot of trucks on pirate, several with 6ATs, a couple done by timm.Comment
