1) Is there any physical difference in the throttle bodies of a 944S2 and 951, meaning the outside dimensions, bolt pattern, and cable attachement location?

2) Does the 951 use the same closed/open/wide open voltage outputs as the S2, or is the voltage output analog?

3) Are the sensor connectors different?

4) If the turbo throttle body cannot be used on the S2 location, AND the turbo TPS is analog, can the turbo TPS be used in the S2 throttle body?

Thanks in advance.

 

the S2 throttle body has a bunch of coolant hoses atached to it. i dont think the turbo one does. so that might already mean you cant put a turbo one on an s2.

 

Coolant lines will be bypassed any way as it doesn't get cold enough here to cause icing. Further investigation has shown that the 951 TPS is analog. If a turbo TB or TPS will fit, will it cause the DME any headaches?

My new line of thinking is to piggyback a GM type TPS on to the stock throttle body to feed an analog signal to the piggyback computer (SMT-7) and run the stock signal to the DME.
