I finally came to the conclusion that I need more power on my GTI VR6. The question is, which is more cost effective:
N/A mods: variable intake manifold, cams, headers, chip, etc..
Forced induction: S/C + exhaust.
My calcs tell me that FI will be slightly more expensive, but with a better hp/$ ratio. I do however perfer N/A engines. Has anyone gone through a similar thought process? Please give me ideas/suggestions. Thanks.

Well, I can tell you on a 2.0, you'll never get enough bolt-ons to give you the hp fi will. I suspect it's the same for a VR6. And, I don't know what a "variable intake manifold" is, but I bet it ain't cheap.
There is no question that fi is more cost effective.

even a tad itty bitty bit of boost will make more than all the non boost things you can do on an engine. just the torque increase is enough. between a vsr, a set of cams , some other stuff, there's the price of boost. get a blower
hehe.
