View Full Version : How do you all hook up ur Profec Bs?

02-12-2003, 02:57 AM
I am trying out different ways to hook up my ebc, and wondering who has most success with a certain way, or is it all the same? My first setup was:
Vacuum line from profec unit teed off of FPR along with boost gauge
Input line hooked to turbo compressor housing
Output line to the wastegate

I tried a second setup, but i'm not sure if it's better or not:
Vacuum line from unit T'eed off Input Line to Turbo compressor housing (to read boost pressure at same time, no need for unit to read vacuum)
Output line left the same at wastegate.

I figured the second configuration runs less vacuum line from the unit (coming from driverside firewall straight to near turbo compressor housing, as opposed to going around the motor to near the throttlebody).

Which do u guys think is better? All opinions and ideas appreciated. Thanks

I always ran one to the actuator and another to the throttle body vaccuum posts which you could T off with the boost gauge.

I have the Profec B as well.

Vacuum source for the unit is from the fpr line.
Others are Ic pipe to greddy solenoid to wg, as normal.
Works fine for me and that's how all my friends have run theirs' on rx-7s/supras,etc.
