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?

From what I've read on the net it needs to be harder than mild steel

Lightweight aluminium flywheel with high grade steel friction area 😎

So, little bit done this morning, but that will have to do as going away for the next several days

First some ring gear removal

then starting the lathe work

My lathe just coping with the diameter of the tdi flywheel 

centre  bored out to fit 1uz crank

Then started machining down thickness to get 1uz ring gear the same distance from starter as it was on flexi plate

thicknessing completed

That looks great

@Stellaghost ....I did wonder who you were trying to convince when you said to me last week you wouldn't start the 1UZ project until next year 

That's a very good finish for cast iron too , quality work as always

Ahhhh, it's become an itch I have to scratch.....

I just need to remember to catch up on house maintenance as well.....

The 1uz conversion will be good to progress on the long dark nights

We spend days discussing the flywheel, and you did it in about half an hour!

Erm, not quite still got diameter to machine to an interference fit for ring gear to slide over

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...

Loads of stuff has VNT's, the TD4 Freelanders use them so that should be easy to find. 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?

They seem to have gone up in price (or maybe I got a bargain) but I'd strongly consider the 1UZ out of a Lexus LS400 (and so would @Bowie69). 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.

You didn’t fancy a nice simple BMW N63 V8 then?

Is that an actual engine or just a scrap bin for hoses and pipes.

@jad Hi

When you built Koya, how did you fasten on the flywheel to the 1uz crank, did you drill out crank holes and re-tap to tdi size or use 1uz bolts

TIA regards Stephen

I don't appear to receive emails when I'm tagged 🤦I had someone turn out the inside to fit over the crank and turn down the outside to fit the ring gear. 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...

Do you not think I have enough trouble with wiring, let alone sorting through that spaghetti..........

Imagine popping down to the parts counter with a damaged hose and asking for a replacement, it could take weeks to work out which one you need! 🤣

Tbf, most of that isn't wiring

Clearly just simpler to swap the whole engine out.

A small but long overdue job on Sid this morning

Rubin, @Bowie69's son made Sids name up from bits of car manufacturers name tags, only right they should be mounted, Sid is chuffed with his name plate, after all its handmade, pretty much like Sid himself 

Regards Stephen 

[Stellaghost]

For anyone that might know this stamp is on the 1uz ECU it reads 95 1 30, could this possibly be a manufacturer date, we would write it as 30/1/95 but I don't know how the Japanese would write it

Japanese most commonly use year, month, day. 

Looks like you may have a early non interference one then..... Maybe.

Flywheel machining completed

ring gear heated up and slipped on

In position

Starter motor cog engaged

some small steel bushes to machine and a brass spigot bush to make to complete clutch side of things
