The thing is, if you want to make a racecar, Drag isnt the way to go either.
The Drag kit is just a better put together kit. Greddy relies on that box, it does have a smaller turbo, so if you're looking to go deep into the teens, you're better off elsewhere. Greddy is also pretty expensive when you throw in the FMIC.
Importparts is having a SICK deal on Drag kits right now...and they are in stock and ready to ship. I dont know where you're getting it from that has a 4 month wait!
