Old VW Motor?

ed_andersen · Posted: Fri Aug 28, 2015 10:43 am Post subject: Old VW Motor?

I have a split case w/ a cast in generator riser w/ dual port heads and carbs. Has not been touched since acquired back in the mid 70's or so. Serial number on front of Gen mount is 20-1125569. Any ideas? VW? Porsche? Let me know. Thanks Ed

Also I checked and crank is an 8 dowel. Block serial # is Type II June 1955 build. Added serial # pics and carb/dist.

I added 5 pictures in Gallery.

A pic will solve the mystery. One tip, a Porsche will have three piece cyl and head top cover tin and a vw will be one piece.

The 20 is stamped in and is quite different then the 1125569 font.

Heads are definetly Porsche.The heater boxes too.So someone could have put Porsche heads and carbs on a VW bottom end.

Started life as an August 55 Bus engine. It would be interesting to see what they did internally (if anything) to compliment the high flowing Porsche heads. It would be REALLY cool to see that thing rebuilt in a Wolfsburg bus!!

You cashed in there, that's an unbelievable find!

That is a early Porsche engine. The early ones used a vw engine case and it could be as big as 1500cc, 1300cc or 1100cc. Don't let anybody steal it from you it is worth good $$$$. The crank and rods are not VW spec and the stroke could be as long as 74mm. Porsche went to there own three piece case in mid 1954. The numbers on the case don't match any in my Porsche spec book for a two piece case.

One thing I am not sure of is the lack of the Porsche tach drive off the oil pump. Could of been someone replaced a bad Porshe case with a VW one.

Also didn't the oil filter tap into the generator stand?

In reply to oil press pickup - look at the gen stand just below motor # boss - there appears to be a tapped hole with a plug in it.

Agree with everything above but I would be interested in seeing a photo of the actual engine #.

Get on the "356 Registry" site as a guest and email them with your engine information, and photos. someone their will be able to tell you exactly what engine that is , what car if was built for etc....

Porsche did modify VW cases for they early 356 cars before they started making their own crank cases. Pre-A Porsche 356's might use this motor and these cars are highly valuable and folks will pay big money to get the correct engine for their restored car (often over the decades the original early Porsche engine's were removed for upgraded motors and the original motor sold off or discarded, hence restorers often need to located the correct motor.)

so contact the 356 Registry, they will have the answer to your question, maybe even a offer to buy it! But since it is not a Four Cam motor don't think you can retire on the proceeds. but it still might be worth a good deal to the right buyer.

Vintage hot rod VW also used this kind of motor, pulled out of a wrecked 356 or a 356 that received a bigger motor back in the day. As Vintage VW speed stuff this motor is also valuable specially with all the period correct air cleaners and carbs.

nice find Laughing

Looks like a Porsche 356 or 912 engine to me but that's based in what my fathers 356 and my 912 engine looks like. Problem is, haven't actually looked at them in a while so I don't remember for sure. For some reason I think the 912 has bigger heads and carbs than that but I could definitely be wrong. Definitely Porsche though so like what was said earlier, don't let it go for VW money. I know with ours we had Porsche guys offer crap money and try to tell us that "it's just a Volkswagen engine" to try to eat us down on price. If you told the same guys that their 356 was just a glorified VW they'd have a stroke. Good luck with it

As stated it is a Porsche 1955 356 engine and the Solex 32PBJ was used one year only I do believe.

The oil filter return hole is in the Gen stand that shows a plug.

I once owned a 57 356A with the 40P11-4 Carbs.

It's likely a Pre-A 356 Porsche engine. As I understand it, the Pre-As had 2-piece engine cases, like a VW engine, then went to 3-piece cases for 356 A/B/C. Rectangular exhaust ports and trapezoidal valve covers indicate Porsche as well.

Unless it's a completely modified VW engine with Porsche components.

Now, if only it had 2 distributors, either mounted in parallel at the heads (early) or near-perpendicular near the fuel pump (later), you would have an incredible (and valuable) engine...

Best,

Thom

If it is a Porsche engine than please explain why the engine number doesn't start with a "P" and instead has a "20-" prefix, which is early bus.

I have had several similar Porsche Engines but never saw one like this with the 2 piece case! Yes the Porsche engines were prefixed with a P!
It would be really exciting to know the Bore and Stroke!

Like I said earlier, most likley it is a porsche engine that had a bad case and someone substuted a vw case. 1954 was the last year to use the two piece VW cases. There were pre A's with the three piece cases.

My 57a has a vw split case diff in it that I put in it many years ago as they are the same (cheap way to fix it) a common practice to use VW parts when there was no difference between them.
