Thank you for the good info and link Samu. I have been looking closely at the Porsche Racing Club Finland site and with help from my wife (she is Finnish and I do not know the language yet!) been trying to compare the regulations etc against the ones from Porsche Club Racing Sweden - and as far as we can see they are the same.
I have already decide that I will get a 944, as it is a lot cheaper to maintain and race than a 911. And as i have said, I want to get a better understanding of the 944 cars than I have today.
What ever option I take (purchase already prepared or not), it will be from Sweden. There is more option and I know the language fluently - easier to negotiate and get the details on a car I am considering.
At the moment I am leaning towards getting a normal street car, importing it to Finland and then preparing it for racing. The car is cheaper that way, i get the racing car I want and it is easier to import to Finland.
The only problem I will have with this is that I know how to get a racing car registration paper from the Swedish SBF, but have no idea how to do this in Finland - but I am sure I will figure it all out.
First step is to get the move from Stockholm to Helsinki all done, and a good garage found. Then i can start looking for the car and initiate the conversion
