The Borla throttle bodies are just that: throttle bodies. For $2k TO START.
You still need a pump, regulator, piping, ECU, wiring, and sensors. Oh yeah, and somebody to program it.
My whole system cost about $1300. If I had to pay for my CB throttle bodies, add $700.
So yeah, complete EFI system for the price of the ITBs. They are NICE, though. But worth THAT much? Not for me.
