Looking for size of hose from stock intake to wrx IC. Is it 2.75 or 3"? What about the 90* hose for the td04 is that one 3" or 2.75" ? Does anyone recall the size of the hose for the PCV that goes from the block to the f-pipe? I am searching but I feel confused and I don't want to order a bunch of parts that don't work!

In my TMIC installation guide, I documented the different sizes of hoses I used...

Ya its a good write up but I am using a TD04 so I need to know what size 90 to use I am reading 65mm or so. so is 2.75" the right size or do I use 3"? Also same goes for between the IC and TB.

i used a 2" id silicone elbow for the td04 to y pipe.

td04 inlet is 2" id as well.

12.7mm is 1/2"

25.4 is 1"

50.8 is 2"

65mm is 2 1/2

76.2 is 3"
101.6 is 4"

I went out to my garage and measured my td04L sitting there. OD diameter of tdo4 outlet is 2.0", same as inlet pipe going into wrx IC. Wrx IC outlet to throttle body is 2.75" OD.

Perfect thanks! LOL!!

YW! My pleasure!
