Hey MrRPJ
Looks like a good fun project. I'm assuming you've seen this thread:

I really like the look of the Subarugears products and have had some email traffic with Todd (who has been very helpful) so will be watching this with a lot of interest to see how you get on with drive shafts, slave cylinders, pedals etc and the impreza box. Any reason you didn't go balls for the 6 speed 'box? I know they're a fair bit more $$$ to buy but it really does make for a more compelling argument for going with a non-native solution to the 915 (for me anyway).
Good luck & lots of photos please
