VM to 200tdi swop

[simdeb]

What could cause me a problem when i swoop the vm engine and box out of my range rover and put a disco 200tdi lump in instead  ?

Has any one done this . The vm engine is fine the clutch / gear box is the problem i have a 200tdi lump that i could fit and its a far better unit than the vm

thanks

Dont know but if you need to change gearbox a mate of mine (local) has a good 5 spd manual  ;)

hi mate just done the conversion in my rangie (200tdi into vm) the you will probably need to change the gearbox as the vm has a smaller shaft than the tdi you will also have to change the chassis mounts for the engine as they are different,down pipe for the exhaust,fuel lines are on opposite sides radiator expansion tank and air box are on opposite sides aswell hope this info helps

I know the 300 TDi engine mounts are different but I didn't know the 200 were.  Anyway, I've a mate who's got on that's been done (not that that helps you much).

How much better is the 200TDi, I know it's meant to be quieter/smoother but is it more powerful?  if the engine is good I'd be tempted to just swap the 'box.  If it's just the input splines that are different (check the ratios) then surely a 200TDi clutch plate will go inside the VM clutch?  I know my mate's car has the original 'box.

the engine mounts on a vm is the same as a v8 angled 200tdi are flat the splines on the gearbox are the same the end which goes into the spigot bush is smaller on the vm
the 200 tdi is quieter maybe with a little less power but not a lot
i used the vm box just changed the bush in the back of the crank which has to be made

the vm seams to have a lot less power than the 200 tdi and with all the problems you can get with the vm thought it might be a good time to swoop over would just be my luck to replace the clutch then  have problems with the vm engine

i would be interested in the vm engine if it's still any good when you take it out  :)

[simdeb]

nothing wrong with it runs well just under powered when got caravan on the back (23 foot twin axle ) other wise its ok , main trouble is the turbo does not come in till around 2000rpm that's OK when its on its not towing  , if i swoop it will give you a pm this week end is decision time

Have you driven a 200TDi then? or a 300?

I tow about 1500Kg with ours and it's ok, car and trailer, but oour 'van is about the same as yours, 23' and 1900kg fully loaded.  I have reservations about using the TDI (the biggest being the clutch) because it's not just the weight but the wind resistance too, at any speed it takes some shifting.

For that I use the LSE, it's a big V8 and it's auto.

Hey all you with 200tdi converted RRC's -can I join your club soon???
I am in the middle of converting my '87 RRC to a Disco 200TDI. It used to be a 2.4VM but has had a Nissan 3.3 the last few years. I am keeping the original LT77 from the VM anf will just make a new spigot bush and fit a bellhousing from a Disco 200.
My problem is that the bellhouising I have bought seperately from the engine seems to be too short meaning that the gearbox shaft is too far out of the bellhousing so it will hit the bottom of the hole for the spigot bush. Any ideas to what has gone wrong???
Is it right that the slave cylinder is on the other side than it was on the VM? Maybe I have the wrong bellhousing...
Also if any of you could post a few pictures of the engine mounts you have welded to the chassis -I better get some inspiration before I start melting iron together.

due to start my conversion but i an using the disco box but you are right that the slave is on the other side  the gear box mounts should be ok just the engine mounts to re due

turbo on my 200 looks to come in around 2-2500 revs, so no great gain!

[simdeb]

yes but on 200 and with a turbo gauge you can alter the boost and when it comes in so you can get turbo at about 1200 revs and with a higher boost but you have to be carefull as to to put too much boost in , but along with it i had fitted a bigger intercooller out of a mr2 and then you have to set up the fueling so it not just one thing to change

[Range Rover Blues]

How do you alter when the turbo comes in then?

The only modification I've found is to fit a turbo boost controller as it eliminates waste-gate creep without altering boost pressure (unless you want to).  A worthwhile mod I found.

[simdeb]

Cant remember exactly what you do as mick did it (arightpest ) think he put a post on about it could be in the disco section will have to ask him ?
