So i was piddling around and typed in rx-8 throttle body in google and I came across a tb spacer. But, BUT it also said that these vehicles also use the same throttle body spacer
Make Model Year Model Info Engine
Mazda Navajo 1991 - 1994 LX, 2 Door
Mazda RX8 2004 - 2004 1.3L, 13B Rotary
Dodge Durango 1998 - 2004
Ford Explorer 1991 - 2003 2 Door
Mazda Navajo 1992 - 1994 2 Door, DX

So it leads me to wonder are the throttle bodys the same for those cars as teh rx-8 I assume? And would they in fact work in our car assuming they are a larger diameter? Because its way cheaper to nab one of those trucks throttle bodys rather than an rx-8's.

 

it might fit the bolt patern but those olders cars are not drive by wire.

 

someone dyno'd with the TB spacer, and I think there were no hp or TQ gains. I think they actually dropped..

 

theres a RX8 to tC spacer kit. Look under RX8 TB in the search button.
