But the questions are:

Whats the difference between hydraulic and solid tappets?

Solid tappets run to higher revs, hence why they are used on STis and higher states of tune.

dont know the answer to your question, but surely it would be easier fitting complete heads that come with the solid lifters as std than changing the wrx ones?
