Larger throttle body?
Just throwing this out there but has anyone tried swapping to a larger throttle body? I was thinking of using one offnthe Toyota V8 engines. They have units that have 65, 70, & 75mm diameter openings. Does anyone know the diameter of the stock throttle body on the 2nd gen? My search skills are coming up short with an answer.
And of course right after I post this I find the stock throttle body opening is 55mm. So that question is answered. I don't know what gains if any this would have to the NA crowd but I think it would be a good way to increase the air flow for the turbo/SC crowd.

Yeah, I found those. I've got a 65mm from a 1GR-FE 4.0L V6 out of a Tacoma, which is a better size for me than the 70mm Mazda one. Should be easier to use on the xB since the RX-8 throttle body has to be opened up and have the sensor contacts switched. I'm hoping this one won't need it. Once it gets here I'll be able to compare it to my spare stock one.
