What is the displacement of my VW aircooled engine?

I have a 1973 Volkswagen Standard Beetle. I can't remember for my life. It's pissing me off too since I know the engine so well I can assemble one in my sleep. When I buy a part, I just buy it for a 1973 46hp. I am almost sure it is 1600, am I right?What is the displacement of my VW aircooled engine?"...I am almost sure it is 1600, am I right?" --YES you are.



Your engine number probably lies between

AF 0,000,802 - AF 0,036,768

delivers 46bhp(DIN)

and is a 1600cc



Edit

If the vehicle contains the standard egine with which it was fitted then for 1973 model period 1 Aug 72 to 31 July 73.



Then it must be the 1600 AF motor which was fitted in 1972 - 73. This motor was not fitted standard after July 73

1600cc.What is the displacement of my VW aircooled engine?It might be. Or a 1500. Or a 1300. As all these engines fit into the car. You really won't know for sure until you pop off a head and measure the diameter of a pot.

I will toss you some numbers on cylinder bores

3.031in. = 1300

3.27 in. = 1500

3.36 in. = 1600

3.36 in. = 1600 Super

Advice: do these measurements "awake"

The stroke is the same on all.

The only difference between a std and a Super is that the Super has dual port heads. so the intake manifold splits into 2 passageways which is easily seen in the engine compartment as you look toward the spark plug area.

Here are some other numbers for more accuracy(just for you)

1300: HP 50-4600 RPM

1500: HP 53-4200 RPM

1600: HP 57-4700 RPM(1970)

1600: HP 60-4400 RPM(Super) carbed.



Now you may not want to go and rip a head off.(I don't). Look at the numbers on the float bowl of the carb. Chances are if it was a complete motor swap the carb would have remained with the accompanying engine rather than swapped.

On the bowls in the casting

30PICT1 -1300

30PICT 2 - 1500

30PICT3 - 1600

34PICT3- 1600Super

But there is no guarantee there either.

And as you are walking in with the 46hp engine order on a 73 car, it is up to the parts guy to determine what to give you.

And 46 hp fits closer to the 1300cc line of engine.

You got the smallest engine that can be fitted into that car. A good motor yes, for dune buggies especially. I would opt for the 1600. So keep your eyes peeled(use a sharp knife) and your ears to the ground(sliced off by the sharp knife)for something "floating around". There should be scads of them.What is the displacement of my VW aircooled engine?
1600 is about right if it is the orig. engine. Except for the cylinders and pistons there is no practical difference in the engine when you buy routine parts.



.What is the displacement of my VW aircooled engine?Hi, If you have the original engine, it is 1600CC like you thought.

The HP doesn't sound right though. I am pretty sure it is more powerful than that!What is the displacement of my VW aircooled engine?
on the case, just under the genny stand, the engine number is stamped.



it will start with 2 letters - these letters denote which engine you have.



since all the air cooled range use the same basic case, any engine couldbe fitted from a 1200 beetle to a 2000cc T4!





Codes beginning - Engine size - Single or Twin port

D 1200cc S/P

F 1300cc S/P

AB 1300cc T/p

AR 1300cc T/P

H, L 1500cc S/P

B 1600cc S/P

AD, AE, AF, AH, AJ, AK, AS 1600cc T/P

another way to find out is if the engine is stripped the use the formula bore x bore x stroke x 0.00314
