I made some progress today. Well kinda. While price shopping around on ebay, I accidentally ordered an oil sandwich sender (no oil flow through directly). I could use it, but it would mean running unfiltered oil to the turbo which I don't want to do. Got a glowshift one on order now. Jacked up the car and mocked up my main charge pipe location. I bought a 2" OD 6' SS pipe for $30 local. The SS is cheaper than aluminum and stronger; if something did hit it the SS will hold up better (and I can weld it if I need to). Unfortunately I stripped the bold on my only 2.5" v-band a few days ago, so extra are on order. I couldn't connect the turbo for mock up because of that. I decided to mount the charge pipe next to the exhaust pipe, with a small 45 degree "u" to clear the rear subframe between the turbo and driveshaft/exhaust section. It will be sitting higher than the exhaust pipe, so that's a bit of protection; not that in 4 years of cx-5 ownership have I ever struck any part of the exhaust. Trying to fit it up in the well near the AWD yoke seemed sketchy, and I want the charge pipe to be as solid as possible so it wasn't ideal. I want silicon connectors, especially underside to be at a minimum. There are a couple of chassis braces that cross the middle of the car; I plan to weld 2 u-clamp style exhaust hangers on them. I will then put some kind of rubber or silicon doo-hicky around the pipe for vibration dampening. I will enter the engine bay on the drivers side, with a 45" bend up into the compartment. I used a 90 deg 2" tube I have to test and it fits through just fine. Most likely I will be routing the oil lines mostly over the underbody panels. I've already ordered a couple of 45 deg SS elbows to weld (see picture of where I will weld). Once I am in the engine bay, I will switch to aluminum 2.5" since it cools quicker. Initiall I will not be running an IC, early testing results will be the determining factor of whether I add one or not.
Turns out that random 90 degree pipe I got to test the welder on will come in handy to clear the middle exhaust hanger.
How the pipe will roughly sit.
The pipe will not be in that location. However you can see some of the bracing I will be welding the hanger on. Also you can see the exhaust hanger I'm using the 90+45 to clear. Maybe if I was using 1" od pipe. Anyone with wrong wheel drive will have that entire well to place a charge pipe AND a turbo (especially the long profile type)
Where the pipe will enter the bay. It will not be sitting side ways like that, but vertical. That's a 90 deg pipe I will be using a 45.
Where it shows up in the engine bay. I may weld a small flex pipe there with a 3 or 4 in SS pipe on it, just to give a bit of movement.
Also someone buy this oil sender lol.
