TB Conversion

[assault187]

Im looking for some Info for swapping a 90 TB to a 91-94 TB. Im told it can be done but I searched and found nothing. You guys know anything?

The 90 throttle body will fit onto the 91-94 DSM perfectly. The only thing that needs to be changed is that you have to replace the 91-94 TPS connector with a 90 TPS sensor connector, the TB's use different TPS but both work exactly the same electronically the only difference is the size of the TPS and the connector's shape.

To swap a 91-94 TB onto a 90 DSM you need to change the fuel rail, because the 91-94 TB have a much larger TPS the fuel rail had to be change to except the larger space that the TB and TPS take up. You also have to change out the TPS connector for this swap also. The only other problem is that the top left bolt for the 91-94 TB is longer than the 90 TB's bolt so you need that bolt also. This is a link for the swap.
