The engine is supposedly 100kg lighter than a tdi, I guess aluminium block helps with that, stuff like the aircon pump will also come off as won't need that, lightweights have plenty of aircon.... What are the adapters for gearbox wise ? Regards Stephen Quote Link to comment Share on other sites More sharing options...

steve b Posted July 27, 2023 Share Posted July 27, 2023 glad to help and equally thanks for the parts from your treasure store. The heater and diff are for the 88 re-chassis you saw and the rear bumperettes are for a friend with an FFR 109 that was de-militarised by a previous owner so they will give the back end some originality again Steve Quote Link to comment Share on other sites More sharing options...
CwazyWabbit Posted July 27, 2023 Share Posted July 27, 2023 Sid is going to be a spritely chap with the higher revving engine AND the 1.003 transfer box Out of curiosity what is the theoretical top speed at the moment and what will it be after the surgery? Anyone know all the numbers to pop in the gearing calculator thingy? Quote Link to comment Share on other sites More sharing options...

dangerous doug Posted July 27, 2023 Share Posted July 27, 2023 If sid is on 37s(can’t quite remember), uses the defender lt77 and the 1uz goes to 8k theoretical speed is over 150mph low table is still the same 1 Quote Link to comment Share on other sites More sharing options...

Bowie69 Posted July 27, 2023 Share Posted July 27, 2023 Just stuffed the numbers in, yes, 3201/3735rpm at 60/70mph with a 1.003. 1 Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted July 27, 2023 Share Posted July 27, 2023 ... and 40" tyres means 2945/3436 at 60/70mph. ... and 44" tyres means 2678/3124 at 60/70mph, which is pretty close to LGT, still a little lower though. 1 Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted July 27, 2023 Share Posted July 27, 2023 ... an overdrive would make it quite palatable on the road 2121/2474 for 60/70mph and 40s, pretty much stock RRC gearing, I think. 1 Quote Link to comment Share on other sites More sharing options...

Yup, I'm not entirely certain 'cruise' would ever be at 70mph in Sid, but I have been proven wrong by Stephen a few times Quote Link to comment Share on other sites More sharing options...

Ed Poore Posted July 27, 2023 Share Posted July 27, 2023 So just how excited are you now? Do you think it'll fit? Note: I said do you think it'll fit not will you make it fit (we know that's going to be the case)! Looking at that photo you appear to be missing the MAF sensor on the intake or did you get it in a box? The bit circled in green 1 Quote Link to comment Share on other sites More sharing options...

Bowie69 Posted July 27, 2023 Share Posted July 27, 2023 6 or 7 wires, if I remember rightly.... No more complex than taking an EFI Rover V8 and shoving it in a Defender. Quote Link to comment Share on other sites More sharing options...

Peaklander Posted July 27, 2023 Share Posted July 27, 2023 Can someone please stop for a minute and summarise why this engine is suitable / more attractive for Sid, compared with other choices and whether or not it can only go in a Lightweight? It's hard for a mere mortal to follow, as you all seem to "know" what's happening and why. Thanks Quote Link to comment Share on other sites More sharing options...
Popular Post Ed Poore Posted July 27, 2023 Popular Post Share Posted July 27, 2023 Okay let's assume everyone wants a V8. So the classic choice is Rover V8 or something else. The 1UZ-FE (which was usually fitted to the Lexus LS400 in this country) basically produces Tdi levels of torque from just above idle to 7000rpm and 265ish horsepower in stock form. So basically towards the upper end of the Rover V8 territory, however with a few minor upgrades (turbos, superchargers etc which are available bolt on) then you can get them up to say 500hp and beyond comfortably on stock internals. Beyond that there are internal upgrades to take them to quadruple digit hp figures. The biggest advantage over the EFI Rover V8s is that you can use the stock ECU to run the engine out of the donor vehicle with a few simple wire mods (basically rewiring some relays to the ignition switch). Thereby saving you the cost of a Megasquirt or something else to run the Rover V8. They also have a hell of a reputation for reliability and are a nice lightweight engine As to what they'll fit in, people have put them in carp loads of vehicles including a variety of Land Rovers. There is a turbo charged version of it in the 3UZ which was a LS430 (more modern), I don't know where it stands with using the stock ecu. The 1UZ is also semi fly by wire in that the throttle pot is actually mounted on top of the engine and you use a cable to drive it so with minor mods any normal cable driven pedal will work meaning you don't need to faff fitting other accelerator pedals. The more you look into it it's a well thought out and very well designed engine. You can even use a standard Defender V8 rad with the standard Lexus hoses because they just fit together. It is a tight fit, will it fit in a lightweight - well Stephen will make it fit. This is the first lightweight I've heard of one going in. Another reason it's attractive for Sid is the 7k rpm factory redline which gives him a much more usable gearing ratio, it can be higher using an after market ecu. 3 2 Quote Link to comment Share on other sites More sharing options...
