    TD5 to V8

    I’ve just been out to check the location of the TD5 radiator outlets and it looks like it shares the same arrangement as the V8 radiators do. Can I just retain my existing rad and expansion tank as it looks man enough for the V8? For the exhaust, do I need to change the Thor manifolds for a set of Defender V8 ones and use the DV8 downpipes and Y piece? Once the Y piece is on the V8, does the rest of the system then run down the passenger (UK) side as the TD5 does? I believe that the standard DV8 exhaust bore will probably be too restrictive for the 4.6 but that the TD5 intermediate and rear sections are okay. To mate up the V8 Y section to the TD5 intermediate section, do I need to fabricate a suitable joint or are there parts that will just bolt together and use the existing exhaust hangers? My aim is to use as many off the shelf items as possible so that spares don’t become an issue in the future.

    Is yours the GEMS or Thor engine?

    How come a Defender V8 pipe can’t be used? I did read about this in your build thread and meant to ask.

    That’s a relief to hear as yes, there are many scare mongers out there. I’ve still got some reading to do on the subject mostly earlier threads on the conversion and the problems others came across but I think I have most of the material now that I’ll need to get it done.

    Another question regarding the issue of leaking thin walled cylinder blocks caused by poor machining. Was this quality issue ever resolved by Landrover before production of the Thor V8 ceased? Or, are the Thor engine blocks just as likely to have similar problems?

    My R380 has the higher ratio transfer box off a Disco 2 fitted. Reading through a couple of members build threads I get the impression that this setup could be a bit over geared for even the 4.6 V8. I’ve always assumed the V8 will out perform any of the Landrover Diesel engines in terms of both power and torque so I’d be interested to hear from anyone who has experience of this. The air box arrangement also seems to present some challenges to get right. With that in mind does the GEMS engine plenum provide a bit more space for pipe work etc than the THOR?
  7. I ended up buying that spring and fitting was no more difficult than the similar ones from the usual suppliers. Well worth the price and effort👍

    Yeah I’ve seen his looms and they look good but I’m talking more about stripping out any redundant TD5 wiring but keeping the bits for things like the starter and alternator as well as temp gauges etc. I really need to study the diagrams and look at my loom in more detail but I’m not fazed by doing that sort of work. I recall that Nige sells loom plugs so I can make sure any alterations are electrically sound and safe.

    So if the engine harness also contains the charging and instrumentation wiring then it sounds like I need to retain it and then adapt it for the V8 requirements. Or strip out the TD5 redundant wiring and make a separate engine loom for the V8.🤔 Either way it will be doable. Cheers.

    Questions about the wiring loom arrangement on a 110 TD5. Is the wiring loom split into sections that can be easily isolated from each other without affecting other parts of they system? I have this circuit diagram but it doesn’t tell me much about the layout. landroverweb.com/Pdf-files/Defender%20MY2002%20Wiring%20Diagram.pdf I’m thinking about the engine loom in particular so for instance, could I disconnect the ECU and the injector loom but retain the charging/ instrument circuit wiring? Same for things like the throttle pedal harness. Could this be simply unplugged from the main loom once it’s no longer required by the V8? Is it possible to buy caps that can fit over the end of unused loom plugs to prevent dirt or moisture from getting in rather than wrapping them with electrical tape etc? Chopping wires isn’t really my thing so if it’s all one loom then I’ll need to think about unwrapping it, pulling the redundant wiring out and then rewrapping it.

    ISV? is that like BTDT?🤷‍♂️

    Cheers, that’s an easy fix then.👍

    Does the Thor use a cable as standard or did they move to fly by wire?

    Could I just fit a complete throttle assembly off a P38 Thor? Or a Defender tdi pedal maybe 🤔

    One other query. Will I need to change my throttle pedal as I think it’s currently an electronic type rather than a cable. What does the Thor engine use?
