So I guess i'm really lucky then, I have a juli 1977 sc with a 930/09 engine (new engine with completely rebuilt with mahle's and now 8000km, 204hp) and SSI. I don't have any limiting things like airpump, airco etc. So this is why it feels so much more responsive then my friends 3.2 carrera!

The floor pans and inner body panels were galvanized as early as at least 1972. More and more galvanizing was used as the years progressed. The first '76 models, actually built in 1975, were fully galvanized except for the roofs of the coupes. By the end of the 1976 model run the cars were fully galvanized.

Pettybird: You are right, I was confused by year, I would have been right for a '76-'77 car.
The 5th digit is up til '80 code for body and engine acc. to PET (Porsche Electronische Teilecatalog or Parts Catalog in English)
Acc. to Bruce Anderson's performance handbook page 43:
'76-'77: 2=911S U.S. 2.7 Liter
3=911/911S Japan 2.7 Liter
6=Carrera 3.0 Liter (My Car)
7=Turbo/Turbo Japan 3.0 Liter
8=Turbo U.S. 3.0 Liter
'78-'79: 2=911 SC U.S. 3.0liter
3=911SC R.o.W & Japan
7=930 Turbo R.o.W. & Japan 3.3 Liter
8=930 Turbo U.S. 3.3 Liter

I think this closes VIN topic for now.

Again you're right about engine, basicly: old type crank 70,4 mm stroke(connecting rod big end was smaller on 3.0 Carrera than SC), 930 belly, 3.0l witout turbo.

K-jetronic: Imagine your car with 3.2L with SSI, no aircon., no airpump, SC gearbox. I've that and it goes to redline in 5th even uphill, and very fast acc. Next project on engine is mass flow kit, chip, KN filter, throttle.
Current project is better brakes.

AHA! So you're planning on a MAF kit!? Then get on it :) I'd love to have you be the ginea pig so I can benefit from your experiences :D :D :D
