Glad to hear you're on the mend, albeit slowly. Are Giuliettas not 4-stud? Looks like the awesome rally one has had a 5-stud conversion (probably from a V6 75). Those 916 GTV wheels will probably be 5x98 so will fit the V6 stud pattern. Are you planning on keeping the DeDion? In a lot of ways I prefer the Giulietta over the 75. It's a lot better proportioned, though I feel the detailing of the 75 is better (front and rear end treatments mainly). Ultimately I have a 75 rather than a Giulietta so I've rather made the decision, but that rally one is making me reconsider! I expect your diesel one will make me reconsider even more  The higher power transaxle models had 5 lug stud patterns. These give you vented discs up front. 4 stud is only available with solid discs. The Gtv6, 75 TS/Tb/v6 and Giulietta Turbodelta came with 5 lug and vented discs .Easy swap. The 75 is really a facelift on the Giulietta bodyshell. The doors actually fit and differ only at the edge under the window where the 75 has that thick plastic strip. 75 dashboard, seats, bench and carpet are a direct fit as well. I prefer the Giulietta over the 75. On styling it's a close call. I don't really like the side profile on the 75, has a kink at the rear panel. The dash from a 75 however looks better as do most of the fabrics they used in the interior. My Giulietta's always felt nimbler as the 75's, nicer to drive. Especially in the beginning of my driving career almost 25 years ago these cars were cheap. I've owned almost every type of 75, 1.6IE /1.8IE/ 2.0TS/ 1.8Tb/ 2.5v6 and 3.0v6. These were also used as donors for my Giulietta's, I've driven a Giulietta with 2.0TS conversion for a long time. And I also build a 3.0v6 at some time. Unfortunately that car gave me a lot of trouble at the wrong moment so I scrapped it. That was a bad decision. The JTD engine will give it easy power and a lot of torque. It will loose some of the weightbalance as it will need a box up front. But with some careful suspension work I can counter that. It's a way better platform to do this to then the Giulia was.  This was my v6 converted Giulietta, with modified 75 bumpers and skirts, low on 17" oz wheels. |

All 6 cyl 75's, Turbo's (petrol and Diesel) and Twin Sparks have 5 bolt pattern (5x98mm.).

Yeah a 3.0l V6 Giulietta sounds awesome! I saw a very nice red one with a 24v swap for sale a few years ago, but well beyond my budget I'm afraid!
I think you might be surprised at the limited amount of difference ditching the transaxle makes. I'm pretty keen on keeping the transaxle on mine, but although moving the gearbox forward makes it more front heavy it does reduce the polar moment of inertia at the same time. How much of each I'm not sure, but it's not all bad in terms of distribution.
Also, I expect moving the battery to the boot would go a long way to offsetting things as well. I'm not sure about the Giulietta but on the 75 it's right up front behind the headlights so way out over the front axle. Popping that in the boot will shift ~20kg front-to-back and help with polar moment of inertia as well. Perhaps not enough to offset the 20v at ~70kg heavier than the Nord, but every little helps!
Does the Giulietta have the same carbon canister as the 75? If so they're 1.5kg. I can't remember if the weight of 1x horn or 2x horns was 685g, but lightweight aftermarket ones are 470g for the pair. I haven't had that much time poking around the rest of my 75's front end, but there may well be more lightweighting opportunities available. Solid flywheel on the 20v or standard dual mass?

The battery will indeed move to the rear to correct the balance a bit.
The Giulietta's have the fuel tank right behind the rear seat, above the axle. The 75 4 cilinder models have the tank in the boot floor behind the axle.
The weight of the JTD engine and ancillaries will most likely be around the weight of the Busso v6. The gearbox will be behind the front axle, that's not so bad.my diff will be a bit lighter as the transaxle but I don't think it will be very noticeable. Gearchange will be much more noticeably improved😅
The dedion gives me plenty of space for a cradle to hold my BMW e36 diff (saved from the Giulia). I'll use the stronger 75 Tb/v6 driveshafts which have the same pcd as the diff flanges, with some simple spacers that should fit rather easily. I expect to be able to fabricate the rear end in a day or so. Brakes will be moved inside the wheels, that's an easy job i've done before.

Would the difference between a Nord and the 20v JTD really be 70kg? Nord is also a quite heavy engine. JTD has some extra stuff like turbo and intercooler that add weight. I'll use a dual mass flywheel for comfort. Solid mass gives a very rattly gearbox which i hate. Car will be my daily driver and needs to provide a small bit of comfort. I'm definitely not going for the all-stripped-out-racecar as I like it to be a bit quiet inside 😅 Giulietta has no carbon cannister. It does have a rather large windscreen wiper reservoir which i'll also relocate to the rear of the car. Pic on enginebay of old partscar..  |

I hadn't thought of relocating the washer reservoir to the rear (or at least further backwards in the car). I'll think about that next car I try to balance.
And yeah, I've got the Nord down at 133kg and the JTD at 200kg, though I don't think I've seen what state of dress either of those are in. I'd believe it though. Iron block, an extra cylinder and general diesel beefiness. Plus a turbo and associated gubbins of course, which I'd expect to be included in the 200kg weight (otherwise it would be exceptionally heavy). Intercooler might not be though.
Yeah I've got a single mass in the Jag and it does chatter. I'd prefer a dual mass, but they don't make them beefy enough to take the torque it'll be making (at least for the E46-shape GS6 gearboxes).
Interesting on the outboard rear discs. Which discs and calipers do you use, and is it just a case of getting some lugs made up, aligning them in place then welding them on?

For the rear i used the bigger facelift 156 rear discs. I believe about 280mm solid discs.These fitted perfect after a little modification of the outside hub diameter.
After that i put the calliper bracket on the disc and spaced that out how I wanted it to sit. Then some cardboard design for the mounting plates that weld to the triangle.
Callipers can be from the 156 as well. These are with a handbrake cable mechanism that can be adapted. Other callipers like Golf mk4 also have that. Or if you're not needing a handbrake, most BMW's have nice callipers as well.

A small update at the end of this year..
I'll start the new year without my neckbrace.😊 As it looks now there is no operation needed as everything seems stable. In 3 months they'll take another x-ray to confirm this but that's just to make sure.
So now I can focus on walking again. I try to walk with crutches outside every day when it's not raining. And do my exercises to regain muscles, strength and flexibility.
Hopefully I'll soon be able to do the things I like.
Thanks all for your kind messages and care!
I wish you all a very healthy and happy new year!

Not much news to share. Still working on my recovery which is not going as fast as i'd like. But i'll get there.. My mate bought a nice Cummins to put in his '71 Suburban. I really like these engines but i guess they might be a bit to large for my Giulietta..🤔    |

They are total monsters! Might ruin the balance of the Alfa chassis somewhat  How's the recovery coming along? |

It's going way slower then I would like but there's still progress. So I guess that's good.
I'm starting to walk with 1 crutch, I've started driving again and I'm slowly getting out of the house a bit.
To get myself mobile again I've bought an Alfa Spider from 1997, 2.0 TS. Small project as it's been stood for like 10 years and it's not running.. thought it would be a quick fix but it's proving to be a bit more difficult then I thought.

Yeah healing always takes longer than you expect, and you tend to feel like you're better before you genuinely are. Still, sounds like you're making good progress. Glad to hear it  I used to think those bat-mask Alfas looked a little weird but they've really grown on me. Excellent looking things. What needs fixing on yours? |

I bought it from a guy I know. He bought it in a batch of cars and parts from someone that has deceased. So the history is unknown. Last APK (mot) was in 2012 or so. Car was cheap so still interesting for me.
It needs maintenance like timingbelt, oil, filters etc. Tyres are gone. Brakes need a fluid change at least.fuelpump seems stuck as well.
But the most annoying thing is it won't start. Engine turns over but there is no spark. Had the ECU immo-off'ed due to a keycode issue but that made no difference. Seems the main relay doesn't get switched by the ECU.
The plan is to look into this further this week.

A friend brought another ecu. Had the immo deleted on it and put it in het car. Changed the fuel pump and put fresh fuel in it. It coughed a bit and wanted to start. Put 8 new plugs in it and it started and idled. I don't want to take anymore chances with this old belt but it seems to run fine. Will swap the timing belt and do some maintenance on it now. Also need to change the cylinders on the clutch. Pedal was stuck.   |

Nice, hope this helps your recovery.
BTW we need more info on the LT as well!

I had one of that generation of Alfa Spiders, it was really beat up without a straight panel on it but it just looked stunning (if you ignored the battle scars!).
One of the prettiest convertibles of its era.

BTW we need more info on the LT as well! That LT belongs to a customer of my mate. It's a 4x4 that was turned into a camper by the owner. It had a 6 cylinder petrol engine which was very thirsty and not very powerful. Note that this thing weighs 4000kg (8000pounds) empty and you need a lorry license.. My mate has converted it to a 2.5 TDI 5 cylinder engine with a mechanical pump. It now has something like 150bhp and way more torque. It drives very good now, quite pokey. Gearing is a bit short but that's not really a problem as you're not allowed to go faster than 80km/h (55mph). Conversion has been checked and approved by the RDW( Dutch governing organisation) this week so the owner can collect it this weekend. I expect him to be quite pleased with how it drives now. |
