Fuel consumption will go up, as well as the cost and sales price.
Conclusion: any significant power increase will increase weight, cost, and fuel consumption.

Add an ACE header and tune. The header is lighter than original. Power increases by about 30-40 whp. No need for brakes, tires, shafts, any of what you counted up there. Fuel consumption does not go up under the same driving conditions.
Even with my JRSC kit, weight didn't increase more than ~40 lbs while power increased about 100 hp. None of the changes you mentioned was needed for normal driving. For the track, an oil cooler is necessary but it is necessary even for an NA. I upgraded with wider tires. But since I replaced with lighter wheels, there was no significant weight change either. Actually, I might have saved some but it is not worth mentioning. Handling is the same. Fuel consumption did not change in the same driving conditions either. I still get 29-30 mpg. That just left me with 100hp extra. Did it ruin my car?
Cut the nonsense, please
