I love my VX, and at about 170bhp its not a slouch, however, having been well & truly obliterated by a 430bhp Atom last weekend (only in a straight line I might add!), I got thinking about what engine transplant would be a good 'un. Not interested in SC's or turbos to be honest, and 250bhp would be plenty. I have a couple of V6 cars also and I like the noise they make, so that got me thinking about a suitable V6 engine transplant. Now the alfa 147 (amongst others) came with a FWD 3.2 V6 which sounds bloody lovely so I'm seriously considering this as an option. Only thing is, I don't want to upset the handling with extra weight and am finding it difficult to source an engine weight for the Alfa V6, anyone got any advice? <iframe width="560" height="315" src="http://www.youtube.c...ed/eruk3QRcUf8" frameborder="0" allowfullscreen></iframe> Many thanks!

Lovely engine and sounds great but its a cast iron lump and weighs a ton.

Vectra V6?

Might be worth a look at this. Also worth a read on Seloc of the accompanying chat, the guy seems to know he's onions but also has no idea how to accept constructive criticism on a Web forum. I had a 3.2 v6 series one Elise. The vw r32 block so that's iron rather than the Audi equivalent. The weight distribution was good as the engine was right upto the bulkhead which you could only get with a vr6 configuration. Although it was far more forward than any other Elise/vx there was no getting away from that extra weight. Obviously around 300bhp helps move it but it changes the character significantly. Hesitant to say but think more TVR Griffith than lightweight precise NA or S1.

Not according to wikipedia.....
"The engine has aluminium alloy block, cylinder head and oil sump and exhaust valves are filled with sodium to avoid overheating"

still haven't found a weight though. God that Elise sounds lurvely.

the later alfa V6's seem to be a GM product anyway:
The demise of the Alfa Romeo V6 came when the 159 was released its V6 engine being sourced from GM, at GM it is referred to as the Alloytec or HFV6 engine (HF stands for high feature)......The GM 3.2 Litre engine has a much more advanced engine management system than its predecessor and this should mean it is a lot more efficient

Ahh yes, thats the same lump. - Bet you'd get a Saab one for realistic cash though.

wikipedia says the 3.2 weighs 168kg!? surely thats wrong!? maybe engine + box weigh that? Can't remember what the 2.2 lump weighs but its nothing like 168 kgs!!

Would it not be easier to just buy an Atom?

eurgghhhh! no roof, you need a helmet, blinkin' fugly, very expensive. nah - where's the challenge???!
anyway, atom is too fast for me :-)

i can't remember the exact block / stroke setup for the 3.2 GM derived engine , but seriously look the z28net , 2.8L and is originally holden, then saab, now vauxhall insignia. it uses the standard gm gearbox bolt pattern , so f23 or m32. the exhaust manifold is nice and compact packaging for the turbo.

I weighed my old tweaked 2.2 engine = 113KG with alternator and itb's

standard z22se = 135kg, cast iron lardy 3.2 would be about 168 kg

But standard vs standard, that's 'only' 33kg more for An extra 60-70 bhp.... Not a bad offset lol
