Hi All,
Require a bit of clareification. ???
What is the difference in the body structure between the Alfetta GTV4 and GTV6.
I stand to be corrected but i don't think there is any is any difference in the "body shell" but differences start appearing with the "bolt ons'. ie bigger fuel tank , bigger brakes & suspension and bigger / heavier running gear ( cooling system, wiring loom, driveshafts, cv's etc).
Gully
Engine mounts are different.
Uprights too, different spindle size and hubs.
Oh, there is this strange hump on the hood.
On a gtv6 the battery is recessed in the boot area where the 4 has the fuel tank, the front radiator area is slightly larger on gtv6, general bracketry is heavier and im pretty sure that the tunnel is larger on gtv6
The early series gtv4 has different radiator support to the late series gtv4 , and the position of the late series gtv4 radiator is different again to the gtv6.
Yes the transmission tunnel isdifferent. I discovered this when i got one cut out of a GTV4 to double-skin the transmission on GTV6 rally car. It is mainly the same except up near the firewall where the GTV6 is about 20mm bigger in radius to the GTV4.
Thanks guys for the info,
I want to convert my 1978 GTV to a V6 but I was worried the body structure when I have to register,
I have no prob's with the mechanicals as I will buy a V6 Alfa 75 for parts :).
I dont want to tell you what to do but you would be far better off selling the 2 litre and buying a gtv6. It will save you a heap of cash and time even if it is possible. Something tells me that a 6 cylinder tailshaft wont go into an early series 2 litre body.
Your second post needs answering. There are two distinct versions of what you term the GTV4 (that name was never used officially and isnt generally used - a simple GTV is the proper name).
The early steel bumpered cars, like yours, have many many differences to the later cars. From the front panels (including radiator support), to the floor pan, rear panels and even the doors. Some of the parts can be swapped reasonably easily but others not so easily.
The GTV6 is closely related to the later GTV's but both are quite different to the earlier cars. Bear in mind also that there are two series of later cars, the pre-isostatic cars (to Sept '84 build) and the isostatic cars (from Oct '84 build) which are essentially built on a 75 chassis with yet another variatioin to the floor pan. That means if you buy a 75 as a donor you will need to make changes to the body up front, in the middle, at the rear, and then to almost all of the bolt on parts.
A number of people have done what you are thinking about but it's not easy and it's not financially sensible.

I concur with Duk, better to get a GTV6 from the start.
Though Choderboy and his mate Jerkyll, both have done the conversion in their later model GTV. Again lot of work, not just dropping motor in.
Keep the steel bumper for a class build.
MD has also done this. I don't think he would do it again.
MMMmmmm :-\,
I will have to turbo the 2 litre ?
The car is just a shell sitting on a hoist at the moment which I have just replaced both rear 1/4 panels and ready to fix both front guards.
I am really after approx 200HP.

Twinspark suitably warmed will give you that. Way to go.
