          Search for a picture of the cylinder head gasket and it will all become clear.

                    Isn't that the engine Iroz Motorsport were using, essentially?

                    Not an advocation for them, try a search if considering, suffice to say VERY lots of money

                      07k engine, neu 5-cylinder engine is indeed what Iroz is using. I thought it was Issam that said that the 07k cylinder head stock will flow more air than a modified 20valve head. 2.5 liters to start with and a better flowing cylinder head, your expenses will be for the parts to make it a longitudinal motor from its original lateral mounting.
                      Saying that, I will be staying with the original 20valve for the foreseeable future.
