Topic: Engine question.

My main questions are did Volkswagen ever make the 1600cc engine as a single port and could my motor be a 1600cc engine with a single port? The mechanic that rebuilt my engine on my 70 Bug told me that it was a 1500cc engine (single port), after taking a quick look at the outside of the motor. The engine number below the generator is missing so I have no number to refer to. Every book that I've read states that in 1970 the Beetle was powered by a 1600cc engine. Since this is true, is it possible that the previous owner had the 1600cc engine repaired and that the mechanic put single port heads on it?
I was thinking that maybe the previous mechanic was "Taking from Peter to pay Paul" to get this engine running again. The books that my father used in the 1960's and 70's says that the 1970 engine had a 30 PICT-3 carburetor on it and that is what I have on my engine.
Another interesting thing is that the two piece throttle positioner was used. In 1966-69 Volkswagen used a one piece throttle positioner, where all the components were mounted underneath the carburetor. On 1970-72, Volkswagen went to a two piece set-up where the actuator portion is mounted near the carburetor and the control portion is mounted on the left side of the engine compartment. My Beetle has the two piece. Maybe the motor was swapped with an older one and that some parts were exchanged. I just thought that I would ask forum members there opinion on this one. Thanks.

Re: Engine question.

Patrick: Yes, the 1970 US models had a 1600 single port. In the '71 model year the US model went to a dual port. See: http://www.vw-resource.com/years.html and scroll down to 1970 and 1971.

Thanks Clancy. I don't know how this mechanic could open up the engine lid and look at the engine for two seconds and state to me that it is a 1500cc engine.

Re: Engine question.

Clancy, I checked out the website you gave me and it describes my engine (to a tee) as a 1600cc engine. I'VE GOT THREE MORE HORSES UNDER THE HOOD THAT I DIDN'T KNOW THAT I HAD (FROM 44HP TO 47HP)!  LOOK OUT ALL YOU CORVETTE OWNERS:) Thanks.

Yeah, a lot of people forget that there ever was a 1600SP engine.  Most just look to see if it is single or dual port.  If it is dual port they automatically assume it is a 1600 (for starters anyway) and then if it is single port they look at the fuel pump and dizzy and decipher whether it is a 1300 or 1500.  I would say it's an honest mistake cause it happen all the time.  We all are probably guilty of it somwhere in our lazy pasts.

VW only made two Beetles...the New Beetle and the Real Beetle!

Now that I know that is a 1600cc, I can feel that extra power:)

Re: Engine question.

help me please!!!!!



The 1600 cc motor starts quick and runs.  There is an issue that I discovered with the motor while doing a valve adjustment, one of the #1 cylinder head studs is stripped and will need a case-saver insert installed for the stud to be secured solid.  I had a local shop that quoted me $70 to have this done with the motor out.  With this being the only issue the car has, it

When you get yourself sorted out as to what it is exactly that you are asking about, you might find better responses if you start a new thread.
