Please help - I'm slightly confused.....
#1
Hi,
Having been pottering around with my car last night (97WRX), I'm confused about a couple of things and would appreciate someone unconfusing me!
As I understood it the wastegate is on the exhaust side of turbo and dump valve the 'output' side of turbo. I have read in many posts that the 'Wastegate solenoid' is on the offside suspension turret. I have found this and traced the pipes (2)- one goes back to the T piece that connects to the dump valve (or what I think is the dump valve). So if this is the wastegate solenoid why does it have a pipe coming from the dump valve??....
Is this solenoid on the turret really the wastegate solenoid?
I also saw (having taken off I/C a sensor of some sort in the exhaust just below the turbo. Is this an exhaust temp sensor?
thanks for any help in clarifying this
Matt.
p.s reason why I want to know is that I was trying to clear up some hesitation at 2k->3k rpm.

No the solenoid has nothing to do with the dump valve, if you look at the DV you can see a vacuum pipe going to the inlet manifold and nowhere else, therefore it's vacuum that controls the DV.

Beastie I reckon you might have hit the nail on the head!..is the FPReg a sort of
cylinder about 2" long and bronze coloured and sort of flanged in the middle?
The pipe I traced from the solenoid goes to a T joint and one way off the T goes towards the offside to this FRregulator(?).
If so - where is the DV?
thanks,
Matt.
