I had just picked up a J's racing 65 mm throttle body and my mechanic tells me he has a 70mm (interior size) unit sitting in his shop. Im just wondering, what would the added benifit be to switch to the larger unit (outside the obvious 5mm larger interior bore).

will there be any problems in switching to this unit, or what kind of gains can i expect from the switch. Im wondering if its worth the switch.

what do you guys think?

With the NA motor, there is little to no gain with ANY aftermarket larger throttle body. In fact, I've read here that some have even had a decrease in performance. In this case, bigger is not always better.

interesting to hear.

Well im doing a baseline run on thurs and then ill do a run with the throttle body. I'll let you guys know if there are any gains with just the throttle body.

I'd be curious to hear your findings!

It's nice having a good list of easy bolt ons for when I get the itch for a little something new, but don't feel like selling my first born to pay for it.
