2.8 Engine
I have the oppotunity to buy a early 911 with steel Turbo flares, Turbo brakes/suspension and a very clean interior with recaros. It has a 2.8 engine that requires a blend of pump premium and high octane race fuel. This engine is an issue since I want to use the car as an occasional R Gruppe street car and for track events. As such, I would like to get a feel for the market valve of this engine.
The engine is based upon an aluminum case with squrters (modified by German Percision), factory Mahle pistons/cylinders, real twin plug 2.8 heads, standard crank/rods and "S" cams. It has 40 webers and an Electromotive crank-fire ignition. The engine has between 8-10K miles and has not been tracked. Should the engine have some real market valve, I would buy the car and the engine's buyer would be able to run the engine prior to purchase. I would be interested in an engine swap plus cash for a modified 3.0/3.2 that runs on pump premium. You opinions would be gratly appreciated. Thanks

Two alternatives. You can have race fuel delivered to your house in 55 gallon drums. There was also a steel-turbo-bodied early car up for sale (on ebay, but the seller is legit) recently with an Andial 3.0 motor in it. A very R Gruppe car.

The problems lies in wanting to drive the car on longer than 150 mile round trips.

That motor is completely worthless. Tell you what, I'll give you $500 for it.
 That's a nice motor. Would be even nicer with high butterfly MFI. (Or slide-valve  ) And maybe a twin-plug Marelli dist. instead of the crank-fire, but that's just for the cool factor. The crank-fire is better from a performance standpoint.Wish I had a nice 3.0 race motor to trade you. I think you may have some luck in the trade dept. but I'm not sure how much cash you'll get along with it. Good luck!

A gallon and a half (or so) of Toluene in a plastic tank in the trunk would do the trick if you had to fill up with 91 octane. Also, you can get race gas at tracks, sometimes even when they're closed, and a lot of other stations.

Sell it to the UK. We can still buy high octane leaded fuel here. It would be great in my 3.0 RS replica!

Sergio,
On the RGruppe classifieds there is a 2.9 twin plug w/915 trans all by Jerry Woods for $11.5K. It's been there for a while, don't know if it sold. You may also want to talk to John Beck as he just had his 2.8 rebuilt.

Jack,
The EBay car is a BLACK car! No more black cars for me. (I feel the same way about black cars as the guy in the movie "Used Cars" felt about red cars.) I just sold an 87 triple black Turbo Look with A/C. Image how hot a back '72 without A/C gets.

True enough about the heat. But that's why you put in AC.

Jack,
What engine are you running in your '72?

It's a stock 964 3.6. It should run on 93 octane, which I try to 'blend up to' on track days. But it comes with a knock sensor, so I'm less likely to have a detonation problem if I don't have the good stuff in there.

PCA7GGR: My question is how modified is "modified?" What sort of modifications do you want or expect on the 3.0?

The 2.8 is a great motor, the make or break question is does it have the the large combustion chamber heads. If not the c/r will be very high and require the gas mixture you describe. I bought a high c/r 2.7 in a single plug configuration w/ mfi on it last year for $3700. Used motors can be pretty hard to sell unless you have a lot of documentation. There was a 77 in canada available a couple of years ago w/ a motor built as you describe that was about 17K. Hope this helps.
