Those measurements are dang close. I'll check out the template when I get a chance and then let you know.

Finished up routing the hoses for the breather lines. My goal was to NOT destroy the stock hosing from the hardlines in front of the intercooler to the connection on the turbo inlet pipe. This way you can go back to stock if you want. Furthermore, by using the stock hose off the inlet duct you won't run the risk of trying to push a new hose on there and cracking that nipple off. That would NOT be fun.

Parts used:
Short piece of 1/2" Heater Hose
Two 3/8" to 1/2" hose connectors
3/8" hose that came with the catch cans

1) I ended up simply disconnecting the hose from the hardline in front of the intercooler and just changing it's placement such that the end disconnected now points to the passenger side. This is the return line from the catch can and dumps into the turbo inlet pipe. To the stock rubber hose I connected one of the adapters and then installed the AMW 3/8" line over the catch can.

2) To the hardline on the intercooler I connected a small section of 1/2" heater hose, the adapter, and then the AMW 3/8" line. I routed it over to the catch can following the same path as the other line. I couldn't get the AMW 3/8" line onto the stock hardline so that's the reason I used a short piece of 1/2" hose.

Everything is in black as to not draw attention to it. Here's the pics of the breather done:

Update,

I finally got around to working on the PCV can. Piece of cake. It's not totally done because I bought the wrong connector. I'll fix that and get pics within the next couple of days. However, simply pop off the stock silver hose clamp from the PCV line at the sensor on the turbo inlet hose. I thought this would be a difficult thing. However, this clamp is 100% reusable even though it doesn't look that way. Pull the hose off the sensor and then slap in a 1/2" to 3/8" hose adapter. The hose then routes directly over to the catch can. From the turbo inlet mount up a new section of 1/2" hose. We can then adapt this to 3/8" and then back to the catch can. Beautiful. Everything is 100% reversible and NOTHING was damaged in the process. w00t.

Pssst. I also installed my hella horns last night. These things are monstrously loud (I installed the relay too so that they get direct battery power).

That looks like an OEM installation - the best kind of mod there is.

Perhaps you could have used a few Ts to only use one can? (I'm not familiar with the ventilation system on the STI though, just asking)

I didn't want to use one can. It is my belief that the systems are separate and should be kept that way (even though they both dump into the Turbo intlet duct). It would have been easy to use one can ... I just followed my belief of separate systems. FURTHERMORE, and this is very important, people here are forgetting that the factory uses two 1/2" lines: one for the breathers and one for PCV. Taking two 1/2" lines and running them through one 3/8" line is just plain stupid (for those running one 3/8" line and T'ing PCV and Breathers). This can cause excessive pressure buildup in the crankcase and blow seals. Moreover, this excessive pressure buildup is also now plumbed back into the crankcase breathers because you tied the system together. I just think this is a bad idea all around. Granted, I am going from 1/2" down to 3/8". However, I have a total of two 3/8" lines working in my system.

I'll need to run the numbers but hose size doesn't scale the way you'd think from a flow perspective.

So 2 - 0.5" hoses should really be combined into 1 - 0.675" hose (or something). You don't double it to get double the flow.

But yes, going down in size for double the flow rate is pretty stupid.

I understand your comments on 1 and 2 systems. Not like the cans are THAT expensive anyway - might as well do it right like you did.

I completely understand that. If I stated something that implied that then I need to reword it. My point is that nobody should be taking two 1/2" lines and combining them both into one 3/8" line. T'ing things together like Perrin suggests does this exact thing - and that is just wrong - IMHO. These cars get a good amount of blowby!

Yup - we're in violent agrement.

killer mod, btw

Thanks!

Today I picked up a 1/2" hose that has a 90 degree premolded bend in it. This will allow me to come off the PCV hose sensor nipple very easily. I'll post info and pics later after I get the final touches on this assembly completed tomorrow morning.

I really like that fact that this whole system was constructed without harming a single factory item and is 100% reversible ... yet 100% functional and very good quality without being pimp. Can't wait to have it totally completed tomorrow.
