I'm sure you'll be able to sell the turbo kits to someone that loves to mod V6 engines but you do realize that MSRP difference between a 2LT/RS and a 2SS/RS is $6620, right?
That gap gets smaller as depreciation kicks in. To price your kit above that range is just asking for fewer and fewer sales. If your target with your turbo kit is at or just slightly above the V8 RWHP, then you need to make sure it's priced right otherwise people are just going to go buy an SS instead. I know I would if I had an extra $7k that I could drop on a turbo for my V6 or just upgrade to a V8.
