I vote with the tb since you already have a cam and boltons, increasing the airflow WILL help. Its when guys throw a ported throttle body on a stock car is when it makes no sense.

I say go for it bigger throttle body means more air and more importantly it speeds up the air. If you find someone to port the throttle body flap Bar between the screws, that will help when 100% open as well

Good luck

Unless the throttle body is bore all the way thru both sides and by the butterfly plate it is pointless. And if it is a TRU BORE throttle body then the tune will be messed up.

From what I have read, the benefit of a larger TB comes when using forced induction. I also read that a member (car was NA) pulled the air filter during a drag run and saw an improvement, which to me suggest the filter is the biggest restrictor not the TB. If anything, swap in the air filter from an HC (MAHLE LX3482) the next time you need a new filter. That is assuming you are still running a stock airbox.

A true 85mm will give you a small gain, but you will need to tune for it.

You're guaranteed to see more gain than spending 1 or 2 grand on aftermarket wheels...😂😂😂. If you threw a cam in already then why not dress it up, just do it for the prospect of a better response and you won't be sorry.
