Unfortunately the length was 16 cm longer, so it will be a really tight fit if it is possible to install it in a Bertone, although this previous thread was about installing it in a 116 GTV. http://www.alfabb.com/bb/forums/engine-conversions/38371-4-0l-maserati-v8-into-116-105-a.html

This engine was in the Autovama Alfetta GT winning the European Gr. 2 series late in the seventies. To our surprise then, it was not a 16V engine in it but the GTAm evolution engine. This car is included in a racecar survey in Sport Auto in 1979, so I still have this clip. Not much is mentioned in the specs, but here it is:

4 cyl in line engine 1985 ccm ( in reality 2012 ccm)
Bore X stroke: 85,1 X 88,5 mm
Power: 182 KW / 248 Hp at 8000 rpm
Torque: 230 Nm at 5800 rpm
Injection: Spica
Sump: wet

Compared with the Bertone GTAm engine 1971, data from the Fusi book

Volume: 1985 ccm
Bore X Stroke: 84,5 X 88,5 mm
Power: 210-240 HP SAE at 7500 rpm
Injection: Spica

Interesting difference to the road 2L engine is a little different bore and volume, and head of course:

Volume 1962 ccm
Bore X stroke: 84 X 88,5 mm

A couple photos of the Autovama champion cars.

That conversion is pure sex!

I can't believe it's virtually a straight bolt up :|

This engine can reach with stock internals 350hp @ crank, and if change the internals 600. I wish i had the money to install a maserati v8, possibly my next project. Andreas

Andreas Alfa you never really answered the question about the brake system. I understand you put BMW calipers. Were thesw direct bolt on or what modifications did you do?

[andreas_alfa]

Oh Im sorry i thought i did, Well the brakes bolted straight on with no modifications at all.

What a fantastic job - love it!

[All torque]

Nice work! Have you got any videos of it?

As someone else mentioned, the only change I'd make is a set of period wheels. But I suppose that may not be possible with the bigger brakes.

[Hans-Peter]

Very neat conversion, I will let others pontificate about if its an Alfa or not but I would happily have a 8C with its Maserati/Ferrari motor in my garage and call it an Alfa, while I would not call the Arna with its brilliant Alfa Sud motor an Alfa at all. Most modern Alfa’s have Fiat or even GM motors!
Anyway very neat conversion, for those of us in this part of the world it makes a lot of sense, I’ve just seen winged sumps available for the SR20 and not even that expensive, I am thinking about doing this in a Berlina and wondered if you could post some photo’s of the engine mounts and underneath the car , gearbox etc.

[pinshaw]

I love it, what a cool setup. More fun,more power and looks pretty straightforward. Hot rodding at its best. Are these SR20 motors pretty easy to find or sought after by the drifter crowd?

[p_lo]

That is a sweet silver and nicely applied I might add. Most people don't like the wheels, however the finish goes perfectly with the colour and bright-work! You might not want to reveal the colour but how about a hint?

[Hans-Peter]

I am in New Zealand currently looking at buying a mint front cut from a damaged Silvia, 65000km, SR20DET which comes with engine/gearbox driveshaft electronics etc etc for about $3500NZ, yes they are sought buy the drifter crowd but their are so many available price is not a problem, I'm sure you know teh cost of getting a nord motor to 200hp, even a T/S will be 4-5 times that amount, not to mention a robust and cheaper to repair gearbox , getting rid of the donut and the ability to tune to 250hp very very easily.

[pinshaw]

i looked online and the entire setup is at most $1800, with engines running from 400 to $750US. Looks like there are a lot of engines from Japan. Look like the oil pan is narrow enough to fit a Giulietta as well, curious, curious.
