Stock VW Engine Identification

1100-1200cc Engines

1200cc Engines can be identified by their vertical intake manifold ends. When the engine is viewed front-to-back the intake manifold ends appear to go straight up. Another feature is the mounting nuts sit on top of the manifold flanges. 1200cc cylinder heads have vertical studs and a flat intake port.

**Please Note** - If you think you have an 1100 or 1200cc engine, we recommend that you check the engine code to verify

1300-1600cc Single Port Engines

1300cc-1600cc Engines use manifolds with ends that slightly bow inwards to match the angle of the intake port on the cylinder heards. The mounting nuts sits inside of the manifold flange when installed. These cylinder heads will only have 1 intake port however it is slightly larger than the intake port on their 1200cc counterparts. The intake port and studs are offset at a slight angle for smoother airflow.

Note: 1970 was the only year VW produced a factory single port 1600cc.

1300-1600cc Dual Port Engines

1600cc Dual Port engines were offered by VW starting in 1967 in Type 3s. Beetles, Ghias and Type 2 Bus models first came with a dual port engine in 1971. They are most easy identified the the dual port end castings which are usually attached to the intake manifold with black or red rubber boots. The dual intake ports and studs are also offset at a slight angle.

Note: Earlier engines can be converted to dual port engines, so it's not uncommon to find dual port 1300cc & 1500cc engines. This was a common practice when brand new single port heads were unavailable.
