As some of you may know I have a rather splendid and frustrating Alfa GTV Lusso.



I really like the styling, the interior, road presence, economy and handling but the oh so typical Alfa melted fuse box means I have no interior fan and even though the twinspark is much better than my old N/A 16V Fiat Coupe I can't help but feel the car needs a little more.
She's a great commuter and I've been enjoying the mostly "A" and "B" road route to work (anything more challenging and the suspension can't keep up).

I have been entertaining the prospect of turbo or supercharging the Twinspark engine. Apparently the 1.9 JTD exhaust manifold fits the engine and the addition of a proper turbo running low boost while the compression ration is standard is fairly straight forward but; as the GTV is a shared platform with the 156 and Fiat Coupe'/Marea/Bravo/Brava and so on and those have an option of a 2.4 20V would a 20V Turbo engine fit the GTV engine bay?

Obviously Fiat Coupe' 20V Turbo engines are a bit of a gamble due to the donor cars being Council Estate chic. Stilo 2.5 blocks with Coupe turbo bits have seen in excess of 500bhp but I don't want to go mad and have an expensive rebuild. I work a lot with the Police service and have been offered an ex-Interceptor 2.3 20V Turbo Volvo T5 for very little money and that engine is bombproof, well looked after and easy to find another (pensioner spec' auto that's hardly seen the light of day) unit should it fail.

If a Fiat engine fits I wonder if the Volvo lump will. scratchchin

The 16V Turbo transplant has been done before but finding a decent enough donor that isn't worth keeping is near impossible.

There are only 72 16V Turbo's left on the road so it would be a sacrifice too far.

My other option is the squeeze the T5 in the middle of my X1/9

At least then steering lock won't be an issue. wink

Do you mean 72 16VT coupes left on the road? The engines were also available in the Delta Integrale's and Thema's so probably a lot more out there then you think to be honest.
Yes only seventy two Fiat Coupe' 16V Turbo cars left on the road. It's a crying shame as I prefer the 16V Turbo to the 20V Turbo. The platform was better suited to the application, the 16V engine was more tunable and produced a better torque curve.

I know that engine was used previously but to keep the 52-reg I would need a car that at least had a catalytic converter.

Also why sacrifice a Thema, Dedra or Delta for a GTV? Those car would be more worthwhile and more fun. The GTV has the show and the Twinspark is enough for normal road use an occasional Audi baiting but I would really like to see what the platform can do unleashed (and I can't afford a V6 yet so modifying my car is a way around it).

Why not just buy and run a Coupe 16vt?

You can't make omelettes without breaking eggs...
Because there are millions of V70 T5's. Okay this is the rarer T5R but still very common.

Believe me "Fiat Coupe 16V Turbo" is second only to Alfa 155 on my search lists.

Oh crud!

There are only 144 Lusso twinsparks left. rolleyes

My Alfa is almost as rare as my X1/9

I wonder out of the 144 GTV Lusso twinsparks left how many have a fuse box that hasn't bloody melted? hehe

You didn't fancy the silver one in Wales which finished yesterday? £510....
Not without the money in my pocket to pay for it. £510 is either the bargain of the year or a bottomless pit.

Does anyone fancy a nice 916 GTV with the usual fusebox issue? wink

I have a cambelt failure 3.0 V6 engine sat in what's left of a GTV in a field in Devon if you're feeling brave... although it's probably better suited to being turned into a coffee table by now. It was a 15 owner RHD converted import too, so likely to have been more than a little abused (I just needed the bonnet, bumper, radiator and headlights!).

5 pot maybe tight between the suspension towers I think, not much space in there anyway... Just need someone with a 20V engine to get the tape measure out I guess.

Popping a Fiat Coupe 20V turbo unit into a GTV would upset the Coupe vs GTV boys as well, all the more reason to do it really.

Or really upset people and pop the 2.4 oil burner in there!
Shame Devon is the other end of the country for me. There are a couple of cheap 2.5 V6's on eBay at the moment.

Wish I hadn't looked now there's this rather lovely P4 164 with a few hours to go.

That 164, bidding at £830? LHD, siezed "barrell" which I take to mean engine, not run for 8 years and V5 missing?

Yes, it would have been a hell of a tool in it's day and but £830? Really?
It went for more than that. 4x4 is what made the money, exceptionally rare.
£1,070

Tarted up and M.O.T'd she'd go for a song. smile
