Generic much lol?
Nah its actually not too bad to throw a whipple on if you can find the kit. Usually around the 2-3k mark for the ax140 kit.
You can also do a MP112 kit too. Ive seen em go for around 2k more or less.
I will say this midnight you are the model for every domestic > import redneck out there dude lol. Oh btw no S/C GP will ever make more power then a Turbo setup. Just saying
You asked for the best gains while dropping 2k. Guess what you will make the most power for 2k on a turbo kit. They can be had for that price all over the forums.
Your deff right about the money aspect but I will say this if you shop around you'll find deals everywhere. Ive saved probably 70% off what everything would of cost new for my entire setup.
