Hi, I have a few questions in the hope that you can help me. I have a Astra F Caravan first registration 10.1993 with the engine X16 SZ 1. it amazes me that this type of engine is naughty after some documents that I could see this is only listed from 94. 2. Which 2 liters of machine can I “set” in my Astra without conflicting with the pollutant standard. What do I have to change everything besides brakes wire harness and control unit? How does it look with the I can hold points if the 2L engine also comes from an astra this take over or differ the suspensions in the different versions (built-year caravan-Limo) Naturally one says that the kadett is “equivalent” to the astra, have a cadett 1.6 with a C16 NZ engine, but with this the stops of the engine look clearly different. In the first line it is about the C20 NE, this I would like to build, however I am of course for I mfg flo _____________________________________________________________________________________________________________________________________________________________________________________________
