OK so this is a bit surprising seeng as I haven't bothered to tinker with this car (too old these days) Last Subaru I plumbed a boost guage to was an 02 STi WRX and it had a nice big alloy intake manifold with easy to get at hoses after the throttle body.
Now I take off the plastic cover and whats this PLASTIC intake manifold thingy? And begin drive by wire where the F^%k is the throttle body? its all hidden under the manifold tubes. BUggered if I can see a simple hose to T off that is definatley after the throttle body. There is one at the front of the motor behind the alternator with a check vale in series, but I am not sure if it comes off before or after the throttle. The only other one is the fuel regulator line that is definatley after the throttle as it is connected to Cyl 4's intake tube, BUT I dont like Teeing off a critical component like the fuel reg
Ideas?
