Throttle Body Question

[sketchman]

Is the B6 TB the same as the B6T? More specifically, is the throttle return spring on each one the same stiffness? And to makes things a touch more arcane, what about the Escort ZX2 TB spring stiffness?

I'm wondering because the stock Festiva spring is too stiff for my liking. I like nearly no resistance. Works better for me. I like an auto trans Neon spring, the one in my 3rd Gen Escort, and the B6T one off the top of my head.

Any thoughts?
