Charge Pipe upgrades

After splitting my stock charge pipe this weekend, I am trying to wrap my head around what fits my Legacy GT.

 

My car doesn't have many mods, it has a Cobb AP with a custom dyno tune, Turbosmart Kompact BPV, 3 port EBCS, and catback exhaust. I am not planning on upgrading my factory IC.

 

The AVO Silicon Charge Pipe seems to be discontinued, same goes the Racer-X charge pipes.

 

I think the 15+ WRX CP are close. I know BPV mount is different, but I am not sure what exactly is needed to adapt them or how exactly how the charge pipe fitment is. What is everyone using?

The 15+ WRX turbo compressor outlet is also rotated and angled differently. Somewhere on here is a picture of their stock charge pipe next to ours and the difference is apparent.

 

I have wondered if the Perrin charge pipe for the WRX would work, but I do not believe anyone has tried it yet.

Is that the main thing that keeps those from fitting?

 

So in reality we'd need some sort of compressor outlet adapter that goes from the 2 bolt flange to a silicone pipe connector?

Dave, I sent you a PM.

the fa20 wrx charge side is at a different angle as already mentioned. I haven't changed my charge pipe but from what I see as long as the flange for the turbo isn't fixed to the pipe itself it should be close enough to good enough. so AEM is a no go. but i would think grimmspeed or maybe nameless would work. please speak up if im wrong. im currently browsing and would like to know

I am working on getting a RacerX charge pipe. If that doesn't work or falls through, I was looking at the various WRX FA20DIT charge pipes and was thinking about hunting to buy some used WRX ones this winter to try the fitment. A pipe like MAP performance that is sold from the turbo mount to pipe obviously isn't going to work. I was thinking the Grimmspeed CP look promising, because it has quite a bit of silicon hose, that should allow for adjustment.

I bought a used 15+ WRX Process West charge pipe as it was a local used part from a Subie group I am in.

 

The turbo section or where BPV attaches fit fine for me and I have a GFB 100% recirv BPV on it.

 

However, what wont work is that the 15+WRX upper pipe is too short in the area near the passenger radiator fan section.

 

The Process West has 2 hard pipe sections. One that connects to the turbo outlet silicone section. The other from that hard pipe to another hard pipe that leads to the TMIC.

 

I found that you would need a long silicone hose or connector to join the 2 hard pipes in order to join the 2 hard pipes in order to clear the area around the coolant hose/passanger radiator fan section.

 

It can be done, but living in Hawaii, I would have to order on ebay/amazon for a 2.5" id silicone hose with the right bends to join the 2 hard pipes together in this section or area.

 

Wouldnt be worth the trouble really for Stage 2 parts and a PDX Cobb protune I have now..

I used http://www.siliconeintakes.com for a lot of the stuff for getting the FMIC kit to work on my RSTi

Also, FWIW, the fitment of the AVO chargepipe is terrible. In hindsight, I wish I would have kept the OEM and simply cut off the intercooler-connection end and bridge this area with a 6-inch silicone coupler. Instead, I have wrestled with the AVO-chargepipe half dozen times to get it to somewhat align with the turbo outlet without jacking-up the BPV connection. In fact, I have swapped the connection from the inlet pipe to BPV with a bent silicone coupler to relieve the mess, but it is still a frigg'n mess that is all caused by the AVO chargepipe.

I love you guys and your research so far but some damn pictures would be great.

 

I am going to join you in the effort to find a easy mod WRX charge pipe to LGT fitment.
