These materials can be found at the junk yard, work shop, hardware stores, autozone and home depot.
The aluminum base is more difficult to find. I bought a custom aluminium base in a work shop.
You have to provide the Renix and Vortec TB gaskets.
It uses the same Renix TPS.
Pics:
On your left is the renix throttle body and at the right the vortec tb.
This is the difference in size between the Renix vs vortec butterflies 52mm and 75mm.
Renix sensors and vortec are in the same side.
The vortec throttle opening is the same way that the Renix.
The mouth of the vortec is 80mm but the neck is reduced to 75mm at the butterfly.
The bottom of the neck is closed up to 70mm.
The Renix plenum entry is 60mm.
