What you got done to it and what are you doing to it?

62mm is adequate for most NA mods. 65 is better for a more heavily modded NA or boosted motor. If you can get a 65 for the same price though, it won't hurt anything to run it on a lightly modded motor.

Thanks Aaron for your input. I wanted to see if a 65mm would do harm to a stock engine.

So completely noob question: does the TB change with the motor or if I upgrade to a 65m and swap an LX9 when my heads go ill be able to reuse the TB?
