When I bought my Super in June it had a dead 1600 in it. We are in the process of building a 2 Ltr with late gearbox and Hyd Clutch. ( I need 1969 peddle box ) Why the 2 Ltr?? Simple to get parts with a phone call. And you get More Power.

Go big? Hell. Just put a 3.0 liter in it.

Because you lose something of the car's original spirit (for want of a better word) when you put in a V6 . I like the tactile and aural experience of driving a car with a nord engine running on carbs. With a V6 or even a twin-spark I think you're changing an old Alfa so that it's more like a modern car. This is a matter of esthetics, of course. I think it's the difference between period-modifications and hot-rodding.

I've had both a 1750 and a 2 liter in my Super for the past 25 years. Started out with a 1750 and std 4:56. Nice combination, and later switched to a 2 liter with a 4:10, which worked excellent, especially driving down to Monterey for Concorso a couple times and pulling good grades over the Siskiyous. Then I decided to install my GTA close box with a std 5th, worked even better! Then, about 4 years ago I wanted a 2 liter for a Duetto I had and decided to build a 1750 for the Super. Didn't work so well with the tall GTA 1st gear and 4:10, just not enough torque. So I recently went back to another fresh 2 liter with the close box and 4:10 and I am again a happy camper. I have 175/70 Avon CR6ZZ on 15 TZ replica wheels, so the tires are a bit on the tall side. I'm building a '65 TI with Twin Spark and close gearbox wth narrowed 2 liter 4:56. We'll have to wait and see how that works. It will probably need a 4:10 at some point, too.

I'm running a much-modified 2 liter with a GTA (actually TI Super 105.16) c/r gearbox w/ std. 5th. with the original 1.3 477 rear end. Abetted by the long first gear of the c/r box, this combination actually works quite well. I have a 4.56 that I intend to install but I'm wondering if you can tell us more about how your Super drives with the 2 liter, c/r box, and the 4.10? In particular, how does the long first gear work with the taller rear-end gears? Initially, this this combination seemed perfect for a mainly street-driven Super but I gave up on it in favor for a 4.56 out of concern that the long first gear wouldn't work well with the 4.10.

It's probably not as fast off the line as it would be with a 4:56, but overall I like it much better. My 2 liter is fairly mild; motronic pistons, 105 48 21 intake (11mm) and std 105 48 exhaust. Magnaflow Exhaust.

Thanks

What compression piston setup are you running? As far as a hydraulic pedal box setup, which years should I be looking for to source one?
FYI, your car pics are amazing! I was really dead set on changing colour to Bianco Spino, but after seeing your verdo muschio I am back on the fence. What a dilemma

I've had installations of 2 L into 101s and the 67 Super.

And the more torque the better.

Your 67 will have the flexible crossover hose, which with a 2L will interfere with the hood strut. The long center one with the internal springs, Good strut but it will interfere with the wire coil that shapes the hose. The wire is not a flexible as one would think. Vibration into the firewall is not good.

If you go for the 2 L, take out the strut. It can't be modified to avoid interference.

This is good news. I suspected that the torque of the 2 liter would compensate for the higher gearing of the long first gear. Fast acceleration off the line isn't nearly as much fun as running up the rpms in that long first gear . . .

Or remove the cross over and left side air box and use the short tubular air box (no snorkel) as in later c. 1969/70 supers (1750 and 2000 Carbed versions).

Sure, but I liked all the aluminum stuff and hose on the original intake.

i think will not be able to use original mechanical fan. an electric one in front of rad is only way to fit. will need to be small D - can't remember - 9" 10"? i think an 11" is too big. works fine btw. stock radiator is adequate size.

67 Giulia Super, 2 liter conversion

I have a 72 Giulia super and I used an 83 spider for a doner, the motor did not need a blanking plate and it had a 410LS diff.
Installed motronic pistons, IAP street cams, 2L euro intake, set of webers, alfaholics fast road suspension their headers and exhaust, 123 distributor, and so on. I did all the work myself expect for the heads and I think I spent less then 7K.
I wanted to do a TS engine but the cost was over 15K just for the motor. My 2L nord has plenty of torque, cams have wide range of power, the 410 works great around town and cruising at 80. This was an easy transplant as my 72 already had hanging pedals and hydraulic clutch. I have an extra set of Webers if your shopping for some.

Your '72 would have hanging pedals, hydraulic clutch and the newer bell housing. Which brings to mind the option of going with a hanging pedals. Obviously you'd need to modify the firewall but it's a lot easier to find hanging pedal box than standing pedal box.
