How to: Upper/Lower IC pipes & EvoX Intercooler
Nice write up. I just got the Evo X FMIC, UICP, and LICP from here. I just want to double check to see if I need to get anything for the install. From the write-up, it looks like all I need is the 6"x1-3/8" tubing for the LICP. Is this correct?
What tubing did you use?
I'm a little lost here I'm a total NOOB, but I have the EVO X LICP, an AMS UICP and of course the EVO X FMIC.
So, for me I just need the 6" x 1 3/8" piping? Everything else should fit good here?
Thanks for posting this great How To up. Couldn't do this stuff without this community.

I believe that 6" inch pipe is for the licp DV outlet to the recirculating DV tube going back to the intake.
You can use anything from even cutting a section from your stock plastic pipe too.

So I finally installed my Evo X intercooler. VelocityHead, this how to is the best. I totally agree with the "you're gonna want to attack the lower IC pipe from about every angle". It took me almost an hour just to get the LICP out. Everything else was smooth.
I ordered the 6"x1-3/8" pipe which fit perfectly. I took some pictures of how I used the pipe. The battery tray fit perfectly after using that pipe.

Sorry, I've been away from the site for over a month...
Good to see you got it figured out. And yes, that 6" extension is for the return line between the LICP and the BOV

Thanks for posting up a DIY OP! I did the install 2 weeks ago
I figured out another way to fix the bov problem.
You don't have to order anything. Just use the stock plastic bov piping and turn it upside down

Yes, if you order the T1R set and an EvoX intercooler, it will work without having the EvoX lower IC pipe.
BUT...at a minimum, you will need to get a larger coupler to connect the RA's LICP to the EvoX IC. The EvoX IC has larger diameter outlets than the RA's stock IC outlets (you might be able to tell by the photo). You will need a reducing coupler, I'm guessing a 2.5in-to-2.0in coupler would do the trick, but I don't remember the exact diameter of the EvoX outlet and RA pipe.

Nice write by the way
Big thank you to the OP for this. I know that it has been a while, but thanks all the same.
This install should take at least an hour (more like 3 for those who haven't ever done something like this before).
The Ultimate-Racing LICP takes care of this little BOV fitment issue. It was a breeze.

Is that the same with the stock uicp. I have stock evo x (not on the car) uicp too but I didnt know if it was even an upgrade from the ra's.
Got mine installed this weekend and can definitely notice the difference with metal IC piping now. Have way more boost through the midrange rpm from where the stock hose would expand.
Definitely think the stock Evo X UICP is wider/larger. It's still a hose though, so I would go metal aftermarket piping.
