Rb25Det Tps On 80Mm Universal Throttle Body

[msmith]

I recently purchased a 80mm Universal Throttle Body, one that required a Q45 TPS.

I was unhappy with this as Q45 TPS sell for $150 and the documentation on loom changes is limited.

I had a look at the TB and noticed a removable spigot on the shaft, this spigot engages the gear in the Q45 TPS. After removing it there is the shaft with a flat surface for a grub screw to mate on.

I made up a cam to sit on this shaft and cut a slot to engage the paddle driven RB25DET TPS.

Care needs to be taken when cutting the slot, you want to engage the TPS is its resting position to give you room for adjustment.

The machining could be much better but i only had a bench drill and some files.
