The stock Throttlebody on the Vivio is a puny approximatly 40mm and must be an intentional limiting factor in the boost seen by the engine.
It is up stream from the supercharger and is mounted directly to the aircleaner assembly. This is just behind the headlight and there is little room for it in this tightly packed engine compartment. When viewing the throttle cable mount you can see it opens in a clockwise direction.
I brought home the thottlebody from a 1992 1600cc Nissan Sentra which seems to measure 50mm. Unfortunetly it opens in a counterclockwise direction.
So Iam appealing for suggestions of common aproximatly 50mm T.B.'s that open in a clockwise direction?
