Hi...I'm from Malaysia...I'm looking at the same conversion too....
What I have now
LR 90, 2.5NA with LT77, electric fan from volvo, brake servo from toyota
What I intend to fit into my LR 90
Disco 300tdi, R380, power steering, radiator with intercooler and axles
What I have found from various forums
- Engine mounting and gearbox mounting would need to be relocated.
- Gear lever will be located at front part of cubby box front instead of original gear lever position. (But since I'm using electric fan, might be possible have gear level at original gear level position by locating engine and gearbox forward. Driving position should be still possible even with gear level at the front part of cubby box position, about 2-3" from original position of transfer box lever)
- Propeller shaft length may need to be customised. (I prefer not to have it customised)
- Wiring can be reuse
- Radiator legs need to be shorten as well as located backward closer to engine as disco hoses & pipings are short. (I might be able to position the engine & gearbox further front as I'm using eletric fan, so more space available between fan and engine)
- Power steering probably direct mount with some mounting adjustment
- Axle should be direct swap
- Use EGR blanking plate to easy the wiring
- Exhaust downpipe should need some fabrication work
- Air filter box either reuse disco or will customise some other air filter box and add in snorkel
I might reuse LT230 transfer box if the half cut disco doesn't come with transfer box. I feel using entire engine, gearbox and transfer box from disco would be easier, then I would just need to customise the propeller shaft. Also, with disco transfer box, the gear ratio is lower, so possible to travel faster on highways.
I will update as soon as the modification takes off. I'm still doing some reading to know what is the amount of work require to be done.
