Crawford AOS install/review thread.

Ok, here are the 08- WRX instructions as a start:

some info here as well:

Will update this post as the proper instructions are updated.

The install is a little time consuming due to differences between the 08 WRX and LGT. As I have mentioned on the other thread, Cusco strut bars will not fit.

 

Removal of the throttle body is not required because the PCV is not directly below it. It is accessible for removal and installation of the included 1/4" pipe plug.

 

The other difference is the location of the recirculation port in the turbo inlet hose-it is directly underneath the manifold and will require temporary removal of the solenoid. On the WRX instruction two black pipes are shown in front of the TMIC. On LGTs they are directly mounted behind and below the manifold and are plastic materials. You will need to disconnect the short rubber nose connection between the recircuation port of the turbo inlet hose and the bottom vent plastic pipe. You will have to manage to get (2) 5/8" hoses- one coming from the firewall side to the recirc port of the turbo inlet hose and the other one coming from the front side of the car to that bottom plastic vent pipe.

 

Connections to the turbo coolant is self-explanatory and easy.

 

Good luck.

Here is the link to my pictures of the Crawford V2 A/O separator.

I had the unheated version on the car for 10 months. I switched it for the heated one last month. Too bad I had to pay a shop 2 hours of labor for the switch.

Could you guys copy/paste your posts here? Please?

Here it is Leo.....

Most of the WRX details are similar.

A couple of details that are different from the WRX instructions. Photos #1-#4 are the check valve, PCV valve and the OEM fitting removals and replacements. The next are photos #3-#4.

Photo #3 shows hoses and where they connect to the can.

Photo #4 is completely different from the WRX. The turbo inlet hose connection is horizontal and pointing towards the rear of the car.

 

I have the can with connections to the turbo coolant. There is a thread here for that.

Hey guys - we are working on sorting out some LGT and WRX specific instructions. Is anyone local that wants to drop their car off for the day and let us install their AOS for free? This will give us a chance to document the install in detail. If you're interested, PM me, or email me at sales@crawfordperformance.com

Here's a quick photo that might help:

This is the actual layout of my installation in an 06 LGT:

#1-5/8" HOSE TO TURBO INLET HOSE. THE RECIRC PORT POINTS TOWARDS THE REAR OF THE CAR AND UNDERNEATH THE

MANIFOLD.

#2-1/2" HOSE TO COOLANT EXP. TANK.

#3-5/8" HOSE CONNECTS TO THE LEFT AND RIGHT HEAD VENTS THAT ARE JOINED TO A "Y" PLASTIC TUBING MOUNTED ON

THE BACK OF THE MANIFOLD. MY #3 HOSE PICKS UP THE VENT PORT ONCE THE SHORT RUBBER HOSE TO THE TURBO

INLET IS REMOVED. THIS CONNECTION TAKES CARE OF HOSES #5 & #6, AS SHOWN ON CRAWFORD'S DIAGRAM.

#4-5/8" TO BREATHER "Y" FITTING.

#5-1/2" TO TURBO COOLANT PORT.

#6-NOT NEEDED IF YOU FOLLOW #3 HOSE INSTALL.

#7-1/2" TO BREATHER "Y" FITTING.

That link for the instructions doesnt seem to work. Here is maybe a newer one I found on the crawford site.

Only problem is the whole thing seems to be about an STI.

Awesome!

Hey guys - feel free to ask questions if you have any!

Here this makes it easier to see:

Just a couple of suggestions to Crawford:

#1 hose is a little short due to the location of the recirc port of the turbo inlet, which is directly below the manifold and towards the front of the manifold. See my post #6, photo #4. Only two options are possible_above the turbo and under the TMIC or just the way I have it.

 

#3 hose requires a 5/8" to 1/2" reducer fitting. The can has a 1/2" outlet and the LGT plastic left/right vent pipe is a 5/8".

This doesn't work at all with the Racer-X FMIC.

 

I need a custom mount and it needs to be just above the pitch stop mounting point.

 

Is there a bracket that can adapt this to that location? I have seen some install itn there.

 

I'll snag a pic and post it up in a bit.

After fideling with it for 30min I now see that if the whole AOS goes 1.5" closer to the firewall (almost, if not just barelly touching it) then it will fit with any FMIC.

 

I need a plate with 4 holes drilled to the same pattern and the plate shaped similar to the built in bracket of the AOS. Then two short bolts (only long onough to secure the two plates) + lockwashers and we should be back in business.

Thanks El Gato.

 

How much longer do you need the #1 hose? Ours seems to be fine, but maybe the TMIC creates a different variable.

 

Our kit removes the plastic vent pipe and runs 1/2" hose, so no reducer is needed.

The reason my #1 hose is short is due to the direction of the top port. If you notice I have a 90 deg. towards the front of the TMIC then it goes 90 deg. down and 90 deg. under the manifold and towards the front to the turbo inlet hose. It's about 4 inches short if you do it my way. Another reason is I plan on putting back my engine cover and trim it at one location only.

 

It is much simpler to keep the plastic vent pipe, in my opinion.

To those who have installed it, any pictures of the little PCV "check valve" that is being capped off or eliminated from the intake?

See link below, post #171. Photo showing highlighted hoses in red. Follow hose on left.

So it was a white one?

here's the photo. The part on the right is the oem pcv and plug on the left is supplied with the kit. Just follow the hose on the left highlighted on the photo of my post #171.

ok, that is in the throttle body, I'm looking for the one (check valve) on the intake tube to the turbo, where the large hose of the PCV connect.
