Hi there, as above i've swapped my WRX inlet manifold for a spec C to rid me of seized TGV's, my problem is they are slightly different so could anyone enlighten me as to where the vacuum hoses and air switch? go which were situated on the offside on the WRX inlet. A tube connected to a nipple almost right behind the throttle body? Pictures or diagrams would be excellent.

From memory - I'll look later!

You should have a 90 degree bent outlet on the front that goes to the purge valve, two threaded holes on the rear one is PCV other need blanking. I used the one on the passenger side for my FPR and the large one on the rear for brake servo.

 

IIRC the Spec C manifold also has an extra temp sensor hole which needs blanking off.....now you have spare wiring to fire up AVCS heads should you go that way

Just need to turn off the CEL for now I guess

hi there timthebat.
i hope you know, you should get a remap as soon as you do this avac removall, or only run car gently without going into boost, can damage engine,
please be aware of this,,

get remap asap, the mapper can then remove the cel light function regarding no avac unit in place, and map as req
best of luck, scoobymike

 

I've got Duncan (racedynamix) coming to tweek my map, I just wanted to make sure he didn't have to waste his time by having to show me where all the tubes with no home have to go!

 

Scoobymike..........it's not the AVCS thats gone it's the Tumble Generator Valves (TGV's)

Shaun

 

Can you shed anymore light on the hole/tapping as i did check but couldn't find any?

 

It's just something I have in the back of my mind that the Spec C had an extra hole for a charge temp sensor......... I might have been dreaming LOL

I'll have a google

Shaun

 

Here's the sensor for sale......

See post 9

IIRC it's under the throttle body, but at my age the memory is a bit flakey LOL

Shaun

 

There is a electrical connector under the throttle body which must be what you're thinking of, but it shouldn't need plugging off?

 

I guess that's the temp sensor then

Shaun

 

so just useing the TGV Deletes from the Spec C manifold on your original manifold wasn't an option??

I guess if you have bought the whole manifold.............In for a penny..

As they say

Shaun

 

They're a one piece manifold unlike my wrx one and the sti version (which don't have tgv's) but are still 3 piece manifolds.
