Can be done. Has been done before and will probably be done again.
The main view is that the engine is too heavy for such a light car and for the power you get you are better off with a 20v turbo. Slightly less work to get it in and much more tuneable.
That being said, if that's what you want to do, don't let me put you off.

What Ben said, especially the subject of weight!

Yes, unless you just want to drive fast in straight lines, a lighter engine will be much more suitable.

I've always liked the idea of this conversion, but the ABF is probably still the best route in my opinion.

The ABF is actually a bit tall for the engine bay, and a 9A is supposed to be the 16v of choice (not that people haven't shoe-horned ABFs in).

Yeah, I believe it's the intake doesn't clear the bonnet, but read a few work arounds.

Not that I'm contemplating this myself, but would a way around the weight issue be to move the battery to the rear? Or is the extra weight of the VR6 considerably more than that of the battery?

According to this link the vr6 is only 75lbs heavier than a 16v, which is 35kg. Moving the battery would help but not all that much.

Take the back seats out and put the engine in the middle...Sorted.

i would actually question the weight saving of moving the battery to the rear, as you'd then have to add an enormous copper cable running front to rear, adding yet more weight. seeing as these cars only need a relatively small battery, you'll probably add as much weight to the front of the car in copper as you will save in moving the battery. only a thought

A 16v is about 10kg heavier than an 8v of the same block type, so that makes it 45kg (about 50% of the 8v engine weight) heavier than the engine your car was born with. You also need to consider the position of that weight, which in general is a bit further forward than the 4 pot engines.

It's your money, the VR6 makes a great noise, and they can make good power. However, I'd go 2.0 16v (and having done it, I can confirm that an ABF fits fine) rather than VR6 - more than enough power for road use, and plenty of tuning bits available.

or go half way in bewteen, and fit a V5. i'd go for the 20v version though. my torpedo has a 10v version, and it is a bit lazy. having said that, the car weights over twice what the rocco does
