I don't want to rebuild or drastically change my car but i would like some HP. I am pondering the 6 to 10 lb kit at about $3500.00. I want some kick but I don't want to cause long term reliability issues.
I think that the most bang for the bucks would be one of these rather than putting a bunch of small stuff on.

Your humble opinions pleeeeze

 

It's the same company. Call them and ask them for their suggestion.
