any one no if a montego engine would pull a 109 or would it be no better then the standard old log burner diesal as in power and mpg :confused

My mate in wales had a 109 monty powered machine he compared the performance slightly better than a 2.5d but with 50% better ecomomy

so whats the best engine swap for some small increase in power not to stressfull to convert and gives good mpg

Depending on what you'd call 'good MPG' there are a few options.

A 2.5 Diesel Turbo from a Ninety/One Ten will drop in nicely (just make sure you get a good one and don't abuse it) and churns out 81 bhp. It gives about 23-27 mpg, which isn't very good for a diesel, but it's an improvment on a petrol engine.

The Montego engine is also a good one. Because it has a much higher redline speed (4600 rpm instead of 4200) than the Land Rover diesels, you can reach a much higher top speed without any gearbox modifications. In standard turbo form you can get 35 mpg. Tweak it and fit and intercooler and you'd get close on 100 bhp and around 28 mpg.

The smaller Peugot diesels (1.8 litre I think) are cheap to fit and I think go in with the minimum of fuss. These turn out about 90 bhp, but I have no idea how this translates to road performance in a Land Rover- I recall someone mentioning that low-speed torque wasn't very good, which stunted progress somewhat.

thanks so it sounds like the montego gives a little more and best mpg does any body no the mods involed in converting it to fit in a 109 my engine is a 2,5 3bearing diesel but it hates hills and does 18squid to around 110 miles was thinking of some sort of bio fuel

You need the monty lump for starters,a bell housing and starter of a ldv 200 van (so the starter motor is on the other side) and a conversion kit from dudleigh conversions,avoid the 2.5 td rover lump as they are more trouble than they are worth.
