does anyone know's if rotrex supercharger fits to a 1.4bbz engine.

what's the difference's between 1.4 bbz and 1.6 EA111 engine;

You could fit it if it's the right size for that engine, there are many different sizes, however you would need to fit different pistons to lower the compression ratio as it's much too high for forced induction on a BBZ.

 

The BBZ and EA111 are completely different engines and they share no common components at all.

 

You would need to do an extensive amount of fabrication to fit the Rotrex in addition to rebuilding the engine and you would also need to fit a complete stand-alone EMS with uprated fuel system. This project would cost you thousands of euros and many weeks of work. The standard gearbox, diff and clutch would not handle the increase in torque and power so you'd need to change/uprate them as well.

 

Not really worth it, sell the Fab and go buy a 1.8T and mod that instead.

or buy a 1.6lt from the polo GTI....

 

or just fit a set of schrick cams, NGK iridum plugs, better air filter & remove the narrow trumpet in the air filter box  & get it properly remapped...ABT did that & got 140bhp & sold it as a kit & a forum member on here had one...
