1968 Porsche 912 restored improved engine making great sounds (sound up!)

SOLD
This is a 1968 Porsche 912 engine built by Vintage Excellence. This is an original 75,000 mile engine that was comprehensively rebuilt with 86mm pistons and cylinders, Neutek SX-1 cam for higher torque, less than 1000 miles on it, just had a fresh Brad Penn 20w50 oil change. It is wearing the original emissions equipment - in working condition, often missing from most 68 912s. Sure you are not required to keep the pollution control on a classic car these days but we decided to keep it for the history behind it and the story.
Please enjoy the multiple scenarios we put this car through to capture the engine working and the sound it makes.

Mark, as always nothing short of perfection. Not sure how I missed this.

What a gem , enjoyed the video and the engine shot under load . The bottom end walk through was fitting for such a terrific machine. Glad to see such an original gem still getting around and the diligent owner showing some mechanical love . Always did like these timeless classics, great video fella

I am working on putting me 62 356 engine in. Excited to see this video. Thanks for sharing.

Another sweet video. This is the first time I've seen a camera shot from inside the engine bay while driving, superb! Reminds me of a dyno pull video but better because you can see the sunlight move around as you drive and go through the gears. That little motor is a real workhorse. How many CCs is the engine now? The fact that you put the smog pump back on is really cool too. So rare nowadays, if someone doesn't want it connected just remove the belt I guess. Keep doing what you do, it makes the Porsche brand so much better, of course I want to buy an early 911 and you might be causing prices to rise so take it easy until I get my car!

Hey Bob, I am trying to capture the true sound of these engines, learning a little more each time. This engine is 1720cc or 86mm “big bore” pistons and cylinders and it has a mild street cam, the rest is stock original parts but there is a large amount of specialty massaging to those parts to make them work a little better. Carburetion is fully restored/machined/jetted just right plus a week of tuning. The other challenge of these early motors is oil leaks which it looks good so far.

.Perfect sound at relantir!!!!

[@bryand3276]

Man that engine sounds like it running very happy, what exhaust do you have on it?

[@vintageexcellence]

Stock exhaust and a nice cam with some tuning

[@bryand3276]

Man 912 stock exhaust Sounds great, I been thinking of getting a more throaty muffler but the more I drive my stock the more I like it

[@Blenzo480]

Awesome video Mark! I like the walkthrough on the engine at the end.

[@vintageexcellence]

Critical strong bottom end info that will be reliable

Hi, what is the part number (name) of the heat shield that sits between the engine and deck lid grill? I cant find it. Can someone please point me in the right direction?

[@vintageexcellence]

@@Gloomwithaview It is called a rain tray. The purpose is to keep rain water off the distributor. It is a plastic part with 6 aluminum stand offs. Only came on 912 but came on all 912s. Not a heat shield and it does not restrict engine cooling air.

[@Gloomwithaview]

@@vintageexcellence thank you very much for the information. I have now found the part

Sehr, sehr gut gemachtes Video. Hat Spaß gemacht es anzusehen. Danke. Gruß aus Düsseldorf in Deutschland 👍🇩🇪

I noticed that the engine had the smog air pump that was unique to the 1968 model year 912s in the US. I purchased a new '68 912 and removed the internal rotors so they were then non-functional. That made it illegal but the engine ran better. Thankfully Porsche got rid of this on 1969 models.
