Any advice on what actually works out there. I know I could supercharge the car, but if I wanted to keep it NA, what are my options besides the F77 package, could I add more for less than the F77 package by using tuner products? Advice appreciated, thanks!

 

Start with the RSS plenum then check out the various threads on exhausts etc.

There have been many threads on the subject.

 

+1 on the Plenum. Probably the best bang for the buck, so it's a good place to start. Then I would start looking at a new exhaust setup (the exhaust sound improvement alone is worth the $), EVO cold air intake, and a GIAC chip flash.

I was a little disappointed in the performance of the stock C2S and after all these mods, the car has truly transformed into what I was looking for.

 

I would do plenum, champion intake, chip, full exhaust

 

champion intake is gonna look hot on ur car.

 

what exactly is a plenum?

 

it's the t-pipe/splitter behind the throttle body. The stock one is a T anyways and the RSS is more like a Y creating less turbulence etc...

 

How much is the RSS plenum ?
How much labor to install ?
what can be expected power wise ?

It is an aluminum pipe tee ,which replaces the factory tee, where the intake air splits to the two cylinder banks.

It's creator claims a power increase of up to 27 hp ( equal to the factory
X-51 package which costs ~ $ 17,000 )

Some users report fantastic power increases, which they can actually feel with their " butt dyno " .
Others argue that their butts may have become super sensitive due to insufficient Vaseline application when they got "hosed" .

Wherever the truth lies ( pun intended) , it will definitely lighten your wallet. And depending on the weight of the currency used , it is quite possible that better accelleration and overall fuel efficiencies could be achieved.

On the other hand, less weight on the rear wheels may result in less traction
(there are no free rides in life )

So use your own judgement . Lol
