Ed Poore Posted July 30, 2023 Share Posted July 30, 2023 To be honest I think if you machined some sleeves (or even plugs) to fill the holes it'll be fine. It's the clamping force that matters more I'd have thought. You could even blob a tack onto the sleeve to stop it moving. Does it actually need to be harder than mild? 1 Quote Link to comment Share on other sites More sharing options...

Ed Poore Posted July 31, 2023 Share Posted July 31, 2023 You're closer than me... I may have a gearbox and transfer box mounted up in a chassis but it's minus a flywheel. My lathe wasn't close to being big enough so farmed that out to a friend but haven't had time to go back and pick it up. Not a race my **** In my defence focus is on moving into the new office / lab space properly then I can hopefully be more productive. Plus the workshop is just downstairs... 2 Quote Link to comment Share on other sites More sharing options...

Controlling it sensibly is the issue, the actual actuation is easy but mapping the response Vs engine parameters (load, RPM, throttle, whatever) is the tricky part. The 2.8 TGV lump is VNT but that uses a fairly basic control scheme that I understand to be not quite optimal, but I don't do diesels or turbos so haven't paid much attention... Most 200TDi's out there are so old and shagged out now it's likely a fulsome rebuild & overhaul of the injector pump etc. could liberate as many ponies as any mods would. Volvo D5 turbos use the same core as the Td5, but is VNT, and according to something I read once are easy to modify to fit a Td5 using the wastegate actuator to drive the mechanism. There's enough Volvos around the breakers to try that option relatively cheaper, aren't there? 1 Quote Link to comment Share on other sites More sharing options...

If you get a complete car then you don't need any aftermarket ECUs to run it just a few relays to direct power to the various pins. I've done this and have some simple to follow wiring diagrams should you want them. There is an off the shelf adapter to an R380 but to be honest someone with your skills would knock one up faster than it could be delivered. They are wide but you have to spend quite a bit of dosh to get a Rover V8 to match the power they are outputting as standard. They've also got a factory redline of 6750 rpm which would help with your gearing issues. I've got one mocked up in a chassis if you want any measurements from it. It's a tight fit in some spots to a Defender body but all workable, that's keeping everything in the factory location. Quite a few people switch the alternator, PAS pump and aircon pump around to free up a lot of space. As things stand the PAS pump is on the drivers side right next to the PAS box and has the reservoir built in. No need to fiddle around with relief pressures like other engines (Cummins spring to mind). The water hoses come out centrally in the engine and using a Defender V8 radiator all the original Lexus hoses are the right diameter and length. Throttle is cable driven rather than electronic (cable drive to the throttle body on top) so you can use the factory pedal. At least in a 110 I've so far found factory LR or Lexus parts that work. The only custom bit so far is engine mounts (annoyingly they are 1" off dropping in the factory 300Tdi chassis mounts). I knew a bit about the Thor vs Gems but I'll let more authorative figures such as @Bowie69 and @FridgeFreezer speak about those. A mate has a GM 6.2 V8 diesel on an R380 in his Defender and it is amazingly torquey. It pulls off at idle in 3rd gear and will do 110km/h all day long if you want to.

I didn't adjust the bolt holes even though they are very different sizes. It should be the clamping force holding it in place. It might have been better to dowel the holes and redrill to the 1uz pcs but I haven't had any problems. Can't remember what I did for the bolts but they definitely would have had to be longer...
