Yup, finally got one. Thanks for all the advice and meeting up so we could check out a "real SZ" in the flesh. We knew we wanted an unmodified one after talking to you / driving yours.Good to hear you got your SZ. Mine is away for the winter up here on Canada
Thanks, Gabor. That's an interesting car for sure. I'll e-mail [email protected] to see if they'd entertain my CF bodywork questions. I'm sure they get these explarotary e-mails monthly 😁from internet tire-kickers (of whom I'm about to be!)Some years ago I posted a sales ad for a Trophy SZ which had been modified a lot even with CF body parts. The car was sold, but I got confirmation that they actually had made CF body parts to make the racer lighter. Also they made a lot more with that car. So really professional people. Never got their name
Hello all, this is an ex SZ Trophy car, number 103. It was fully rebuilt in The Netherlands by AutoHeida a few years ago, including all new and much lighter bodywork (FRP I think, not carbon but never the less very much lighter than original). It also has a 3.2 24V GTA engine with double carbon intake plenum. It currently lives in Belgium and is owned by mr. Jacques Peirs of JAC cars.Some years ago I posted a sales ad for a Trophy SZ which had been modified a lot even with CF body parts.

Here a link to to my post 7 years ago:
Also a SZ race car on track, maybe the same?Probably most by now know that the SZ(ES30) is a car based on the 75 IMSA racecar technology with regards of the chassis and suspension. Difference in engine though, as 1,8 R4 turbo in the IMSA, while 3,0 V6 12V in the SZ. The SZ has 210Hp for the road so there has been some projects to increase...www.alfabb.com
Nizam, regarding your question for photo's of carbon fibre parts. In Japan are a number of companies that have replicated a large number of parts in carbon for the SZ (and RZ). Many of them are used for racing in special Alfa Romeo racing series. I have added some pictures. If you are interested, a company like scuderia oldtimer (www.s-oldtimer.com) makes a lot of these parts and even has their own racer. Now you asked for pictures, so here they are.Yup - should have been there. The Alfa Romeo Owners of Southern California (AROSC) will be doing this again in 2020, and it will be their 50th anniversary. We hope we can drum up a few more rare cars like the SZ to come to the party. Laguna Seca is a pretty fun place to be in an Alfa Romeo.
I think I've seen a double-plenum conversion but it wasn't in a SZ.
Separate question; does anyone have pics of a SZ with carbon fiber panels (e.g. bonnet, doors, wings/fenders)?
Hello Nizam, yes I think that most owners like me did not expect the bonnet to be as heavy as it is (from the top of my head some 29 kilogram) and a carbon or polyester bonnet saves a lot of weight where it matters when turning in.Thanks for the info Robin!
Actually, as most of you who have already experienced how heavy the bonnet/hood is, would immediately see the benefit of a lighter unit.
If there was less weight in the nose, I think my turn in would be a lot sharper (it's already pretty good) and going up the back straight of Laguna Seca would probably be more enjoyable since it's a steep uphill climb. That's my motivation.
Have any of you had issues with air getting under the bonnet and attempting to lift it open while driving at high speeds? (i.e. > 200km/h)
Weight is always the enemy. Moving weight around helps, too, BTW. I moved my 75's battery from the driver's front corner to the rear passenger (in the boot). That 20kg alone helped a great deal as it was so far forward.... its a big drawback on the track.
I assume it will flutter worse since it's the same design, and has less mass. Hood pins are a must, preferably on all four corners. Keeping the hinges will mean it has six mounting points, which will hopefully reduce flutter.Then wonder if a light CF bonnet on the SZ would flutter even more than the 30kg original?
Actually, I used the part number you posted, but wanted the keylock. I was still skeptical because I have several Alfa 75s -- but they aren't the 4-cyl models -- and the cap had a larger inner diameter.Just as I wrote, maybe you did not read.
