|In this section you can select three torque and BHP graphs
of the Alfa 33, and also some technical specifications of the boxer 16v.
The 33 was delivered with three sorts of 1712 cc 4 cylinder boxer engines
(boxer because the "flat four" punches (like a boxer) it's cylinderheads
to the side). Two of them are basicly the same (hydrolic tappets and both
2 valves per cylinder), only difference is the fuel supply.
