each of those kits will get more power out of a inline 6 but you have to keep the reliablility in mind.....if you properly prepare your engine to take more boost then just fit an intercooler & turn the boost up....otherwise stick with what you got....I would go with CAPA only because I've never heard of the other brand/company
If a 168rwkw blown I6 was up against a 175rwkw mock motor, I would be putting my money on the blown car thats for sure.
Don't even bother comparing forced induction figures to a car with a cam and head work.
