I was thinking about doing the tb mod, and i have an s4 tb laying around. The car that i am doing the mod to is an s5 motor. Is there a difference between the tb's. Oh yea both cars are non turbo.

the tps mounts differently, thats basically it

what exactily do you do to the tb, when you do the mod. Do you have a link of a write up of it?

I dont understand why you are swapping TB's. The mod itself takes like 20 mins to do? Anyways I dont even think there is any modification needed.

For the TB mod, look here.
