Whats the difference between the 911 and 912?
 

Im new to these (bought a 67 912 yesterday) and will be restoring the car. I know about the motor differences. I want to know about the interior/trim/ body differences. Help is greatly appreciated.

You may want to pick up the "Guide to Restoration and Authenticity" book(s) by Dr. Brett Johnson. I think they do a pretty good job of explaining the details and differences of various models & years.

About a 100 horsepower.

we 912 owners make up in courage what 911 owners douse with horsepower and commonality (or that's what we tell ourselves!)

About 100 horsepower! I don't think so! Try about 20 horsepower between the original 911 and 912 (110 to 90). And with the 912 you get better handling, so ha!

Just had a quick look through "Porsche Buyers Guide" by Batchelor and Leffingwell and here are some of the differences:
912 uses the 1582cc flat four from the 356SC. It was slighly detuned form the SC's 95HP to 90 due to larger air filters and 911 look alike exhausts.
The instrument panel on the early cars had only 3 dials, speedo,tachometer and combined fuel and temp gauges which were similar to the 356SC.In 65 Webasto gasoline heaters were available and in 66 the track was widened.In 67 the 5 dial dash became standard and safety door locks were added. Interior carpeting was upgraded and new engine mounts were fitted. In 69 the wheelbase was lengthened.
It also states that engine maintenance should be less that that of a 911 but that some mechanics recommend replacing the 912 engine if major repairs are needed. The 912 crankshaft is viewed as the weak link in the engine.

Hope this helps

While owners of the "better handling" 912's contemplate their spindly crankshafts, they should view Harry Pellows excellent 356/912 website at:

While the "spindly crankshafts" may be an issue, the 912 is fun car with good parts availability overall. Check out the seatbelts and upgrade to three point if needed.

My first was 67 (in 1994) and I later switched to a 69. I found getting parts for the 69 was easier, and like the long wheel base. The long hood is classic, and the chrome gives it a distinctly early look.

The back seats are small, but my back seats old toddler seats for my four year old twins with no problem. It is a solid around the town car and the maintenance, with the relatively simple engine, etc. is handy. I found an AZ parts car like yours for next to nothing and it serves as an organ donor w/ spare engine/tranny, etc. Overall the cost for daily driving is very comparable to a newer Honda and is certainly more fun.

If you get to race on the weekends, with some planning you can plug in a larger engine, and really take the frame in a number of different directions - see Clay's web page for example.

Of course, if you have the means, a 78-83 SC is nice.

Backroads in AZ at 85 (w/o twins) isn't terribly fast but the roadfeel is 110 http://www.pelicanparts.com/ultimate/smile.gif

I know a stock 912 can do 120mph. I can vouch for that. I have the photo to prove it. Actually its a hair over 120mph and its right at redline.

-1?

How can a photo prove that a 912 is doing 120? Is it a photo of the readout on a radar gun?
Because you surely aren't referring to a pic of the speedo, which is really just for entertainment purposes at high speeds, and has no relation to the speed of the car!

A snapshot would have to show the tach. The true speed could then be confirmed by the gearing of the transaxle and the specific rear tire size.

Or, how big the bug-splatter is if you knew the size and density of the bug in question prior to impact?

Actually its got a the tach in the picture too. Its a little over 6,000RPM in fifth gear.

A 120 mph 912? The stuff dreams are made of.

Not to ruin your day Hoff944, but what size tires do you have on the 912. My 912 can go up and beyond 6000 rpm in 5th gear but it ain't going 120 mph! But then again I haven't tried for 120 yet! http://www.pelicanparts.com/ultimate/smile.gif

The wheels were the stock 4.5 x 15 with 165HR tires at the time of the photo. I wish I could get this photo scanned just to show you nevertheless. Whether we were really going 120mph or not, its still a cool pic.
