Hi

I've only had my WRX for a few weeks and feel the need to start modifying already, I've bought a single gauge Pod and am awaiting the delivery of my 52mm turbo gauge, trouble is I cannot for the life of me work out which pipe in the engine bay I need to cut the T-piece into for the vacume hose!!

Any help would be greatly appreaciated.

Thanks
Arron

the one from the dump valve. I bought a T piece then used a bit of extra pipe to join back to the dmp valve.. you'll have to get one where the T bit is a smaler bore...

can't remember where I got mine from though...

Thanks for that, when it arrives I'll give that a go, in the meantime I'll be on the hunt for a T-piece.

Have now fitted the turbo gauge and tapped into the hose on the dv, however at idle and normal (slow) driving conditions the needle sits at -10 to -20 psi, only when I really put my foot down does it move to +5 psi upwards, is this correct, also when I change gear the needle snaps back to -30psi and then slowly creaps up towards 0.

Thanks for the help, just a bit worried as the needle is not quite where I had expected it to be.

Cheers

At idle and low power the manifold is in a state of vacuum or negative pressure (compared to positive atmospheric pressure) hence the minus boost. When the turbo spools due to the exhaust flow at higher power / rpm will you see positove boost.

At idle on a good engine you should see 12-15hg. Hence when the engoine is off but the ignition is in the on position the guage shouls read aproximately zero.

Hpe this helps

Arronb,

What year was your car manufactured as I have just bought a July 2005 Sti from Japan (JDM) and am looking for a a-pillar pod for it for twin gauges

Sorry been really busy at work, my car is an MY06, got the pod from Scoobyparts, really good fit and good quality, however am going to bond it on rather than use the self tapper sullpied.

Thanks
