Hi all, 


Im new to Subaru's and i have recently gotten an 06 Subaru Liberty Blitzen with a H6 (122XXX) and i am thinking about modifying the car to get more power out of it. 

Im not too familiar with mods that have been done to the H6 engine but i found there is a supercharger kit available from Raptor for 5200$, which is pretty expensive but is an option that i am looking at. Is supercharging a good idea for the engine? 


Are turbo mods popular with the H6? 


Any information about modifications you know that people have done or you have done yourself would be awesome!


Thanks all!

E85, tune and headers/exhaust are the most common for the H6.

Good gains to be made with boost but you are very limited by the factory internals. Not a super common thing to do as its costly. I believe most places charge around 10k for a drive in drive out turbo. All custom work.

Supercharging can be done in your shed but youll still need a tune
