no its not about your ****-n-***** . i am considering getting a 66-68mm billet throttle body. i am currently running a 64mm right now, but it is sticking and am in the market for a new one. i have read in past threads that a throttle body can actually make you loose power, of which i dont want, but none of the threads specified just how big is too big. i am considering the spoon, even though it is tappered, and erics racing billet TB. also, will port matching the manifold be ABSOLUTELY necessary if going that big. thanks

matching the manifold is always necessary.
I doubt you'd see any gains with that large of a TB.

 

is the stock ITR 62..??

 

unless you have a fully built motor.....you really dont need a bigger throtle body.

 

yes, 62mm.
