Re: NEED HELP(Which Throttle Body)

Which throttle body size for a plenum depends on the horsepower you will be regularly targeting

* stock CA18DE (131 hp) 42mm/70mm
* stock CA18DET (167 hp) 55mm/70mm
* modded CA18DET (400 hp) 68mm

The smaller number is the size of the throttle bore & throttle blade, the larger is the external pipe connection

You can go a bit smaller if you will rarely be revving the engine up to the peak HP
