subaru supercharger!!
 

As above one has been listed on ebay taken from a bmw mini and fabricated to work perfectly on a impreza lump looks like an ideal peice of kit was made to run with 2 td06 turbos or just the single!! cant ad the link but im sure you can just type subaru supercharger on ebay

nice one!

Where is the inlet manifold going to fit?

your going to require an awful lot more pipework, etc. to even think about that working

There is a supercharger kit for the brz now

Would of been nice to see it fully fitted.
No idea how that would connect up to head.
The inlet manifold would need alot of work and no idea where all the fuel lines, vacum pipes and coolant pipes would go, that norally sit under the inlet.
