Can a 997 GT3 82mm throttle body fit a boxster?

Im very close to buying the IPD plenum for my 3.2 I recently purchased the 997 75mm throttle body. But I read that theres a 82mm setup with the IPD.

Would the GT3 82mm TB fit the 3.2 boxsters? or is 75mm the biggest?

I don't know if it will fit because I do know it will lower torque at low rpms so don't waste your money.

I've got a 996 75mm TB on my car. I used an aftermarket piece of flexible intake ducting to connect between the new TB and the MAF, and the tubing just barely fit. I've got a feeling that if you used tubing for a larger diameter TB you might need to do some body surgery to make it fit. Good luck!
BTW, I didn't lose any torque. Actually, the mid range seems to be where I gained the most.
