Sierra 16i CLX info

Hi everybody. I would like to ask you if someone can help me to distinguish the type of engine my car has got.:shakehead

It's a '90 model bought originally in Germany and it has got catalyt converter.

My main questions are if the engine is full injection or if it has got a carbyrator. Then what kind of modifications can I do and does the engine has the abillity to 'accept' an air intake such as KnN or something similar?:screwy:

Thanks in advance

I forgot to mention the engine is 1600cc as it seems above.

I have changed the exhaust system behind the catalyst until the end with a 52mm stainless steel pipe, took off the silencer and the back box is a custom with 120mm end.

Also I changed the manifold with a 4-1 custom one. I tried to replace the factory air filter by using a simota intake filter but the result is crap (noise not at all).

More, the oil I use is synthetic 10W40 but somebody told me to use 20W50 oil for this engine.

And what about changing the back drums with brake discs? Is it easy?

You probly have EFI and you can add a K&N, and there are plunty of mods you can do just do a search for what your looking for.
