what have you lot used for the cooling rad as the 3.9 has engine cooler going to the rad and also has a auto box cooler,dose the rangy one fit?or do i keep the 200tdi one and buy a after market oil cooler for the autobox?

I got a mocal engine oil cooler with an inline thermostat. A local shop did the custom lines....probably spent just as much as I would have for the proper rad (still using my old 110 rad) but it looks good and should keep it plenty cool.
 
Let us know how you're getting on, malcs90. I did the same thing with my 90 and its great.

The wiring is pretty straightforward, The EFI loom comes out of the rangie a piece of cake, there is a multiplug next to your left ankle (when sat in drivers seat) that needs disconecting, and the ECU (under drivers seat). Then all the wiring you need will pull through the bulkhead from the engine side through a hole just big enough for the ECU plug. Measure this hole, as landrover used 2 different sizes, and drill the same size in you 90 so you can use that nice big rubber grommet again. I managed to get mine through next to the fuse box (and covered it with the plastic fusebox cover) then ran the wiring along the tunnel under the carpet and mounted the ECU up between the seats, out of harms way (water).

At the white multiplug, the big fat brown and orange cable needs a permanent live from battery, no need to fuse it as it is fused at the ECU end of the loom, once for ign, and again for fuel pump. The 2 relays there are IGN (black base) and fuel pump (blue base) The white wire with a grey stripe needs an ign live ,from key, and the purple and white wire is the positive feed for your fuel pump. The only other essential wiring is a -ve input from coil, mark this on disassembly. As you're taking out a diesel, use the wire to the stop solenoid on the diesel pump as your coil +ve. Mark up the oil pressure switch wire, temp sender wire and alternator connections as you remove them from the diesel, you may need to extend /shorten these as neccessary.

I didn't bother with the speed transducer input for the ECU, and although this may mean that I am only running on an 'idle' fuel map, it still kicks arse.

The props I used are both the same, and are Rangerover v8 auto front props.

Didn't realise how long I had been ranting on, but hope this helps. shout up if there's owt I can help with, Dave.
 
thats great dave im in middle of stripping the range rover i have taken out the engine and the engine loom through the bulk head like you mentioned engine is out the defender and box and sold ,in going to get the auto box out this week and cut and weld the v8 mounts on il do some pics tomz
 
cheers mate,i was meant to take pics but havent had chance yet but will bring camera into work tomz can any of you lot post pics of your efi defenders engine bays thanks
 
the v8 will fit in there a treat not sure about the auto box but if you got a complete range rover take the back axle out and put it in the 90 youll need it and its got disc brakes to ive got a 90 with a 3.9 v8 efi on a manuel box but not hade it going yet. if you got the v8 in rangy still please could you take a picture of the wireing from coil to distributor as i need it to get it going if you take the pics please will you send them to [email protected]

4/where dose the two heater water pipes go on the 3.9 efi engine?

5/what size fuel pipe will i need to conect to the v8 and fuel pump?

6/will my 90,s speedo go in the 4 speed auto box?

7/how can i fit my 90,s handbrake lever to the autos hand brake(so i still got the handbrake on the seatbox)
