911 turbo vs 930 turbo

what was the basic differences when porsche made a 911 turbo into a 930 turbo. I am looking at a 84 930 Turbo and all the stickers and manuals say 911 turbo. Im a newbie.

the quick answer is that it's the same thing. 930 was the internal factory designation for the turbo.

yes, just like 996 or 997 is the internal designation for the newer cars, the "model designation" is still a 911.

Most that have one call it a 930. Then there is the 965 which is the 91-94 911 Turbo.

930 = 911 Turbo from 1974 to 1989

Compared to the 911, the 911 Turbo had added anti-dive in the front and rear suspension, wider front and rear tracks, wider fenders, wider wheels, wider tires, better anti-roll bar kinematics, and the Turbo engine. From 1978 onward, it had massive finned Aluminum brakes also used on the 917/30 and 935s.

Real 930 or not...

I don't know of your location in the world, but I do know that there were no legal US versions of 911/930 Turbo's sold in the United States.

If you are in the US, you may have a gray-market version...write down the VIN, and call a local Porsche dealer to verify if it is 'gray' or not. A gray version may be difficult at best to have smogged, or difficulty in parts, inability to get 93-96 octane fuel which the Euro cars ran on.

In other word's, proceed with extreme caution.

Good luck!

Not true. They were sold in the states from 1976-1979, not sold from 1980-1985, then started selling again in 1986. I've read that there are a handful of legal early production 1980 cars that exist too but they are rare.

Not true either... my 83' 930 passed Colorado(USA) emissions with flying colors.

what octane fuel are you running? I believe the engine to be the 330bhp? Im a newbie so forgive the wording on the engine size if not correct but yes its most definitely gray market and has been stateside since birth(84) and its a turbo with the larger factory engine. I know it has passed emissions as it has been owned by a family member since practically new.

Here in CO we have very few 93 octane pumps, so I am stuck running 91 octane.

Porsche used the 3.3L turbo until 94' when they went to a 3.6L turbo motor for the final 965 year. I believe that the Euro 930 is rated at 300hp at the crank.

"91"?!

FFS! Isn't that low-grade stuff stupidly dangerous for your engines?!

Even our cheap stuff (which is anything but cheap) is 95... Run my thirsty 930 on 98 or 99

91 is it here in California. And it has Ethanol up to 10%. There is one station near me that sells 100 octane 'racing fuel' but it is twice as expensive. It smells funny, too, but I believe it is unleaded. I thought European Octane was measured differently and so your 95 would be 93 or so here.

Phew!

Thanks for the explanation - otherwise I thought you guys would be wincing every time the boost needle passed 0.2Bar

sticker in my gas tank filler says 89 octane is fine as long as no high speed driving. Factory owners Manual says the same for my 1979 930 turbo.
You should be fine with a stock engine on 91 octane. The US cars were designed for our crappy gas from the beginning.
Calling it a 930 sounds cooler than 911 turbo anyway. Every afficiando knows what a 930 is when you say it.....and if they dont that gives you a chance to explain it to them and talk about the car.

Back when the 930 came out Sunoco still mixed a few levels of high octane gas in the pump.

The highest octane was called called Sunoco 260 if i recall correctly and it was very good high octane gas.
It disappeared around 1979-1980 but alot of the pumps still had the custom octane mixes listed on them with the selection buttons into the early eightees.

A 964T or C2T is not actually a 965 either but we call it that. Internal designations are more fun for the enthusiast than the consumer car nomenclature.

I use 89 octane fuel in my car. Stock boost, conservative timing and a big intercooler you can do that. I never worry about finding high test gas.

All true.. But just to muddy the waters Not all things that carry a 930 part number were originally destined for a 930 '911 turbo'... "Super Carrera (SC), ahem.."
