My 10.5 Hotside Install & How-To
Interested in installing a 10.5 Hotside? Not a big fan of having to pull your turbo? Read up!
So I decided to install a 10.5 Hotside and a Megan Racing O2 Housing before getting dyno tuned again. Here's what I bought and what you'll need to do the install. You'll need everything here minus the O2 to install a hotside if you want to retain your stock O2.
The first thing you'll have to do is remove the stock undertray, and downpipe. These are simple tasks to I didn't take pictures. Once you've got those parts out you'll look up at the stock turbo outlet and see this...
^ Remove the black bracket holding the O2 housing to the Block. You're done under the car for now.
Next remove the manifold heatshield...
Then the O2 Sensor and the lower heatshield...
You'll have to disconnect the O2 sensor under the coil pack cover...

You'll need to pull this clip to remove the wastegate actuator arm from the Turbine Housing...
Voila!
Then you'll need to remove the manifold. Once you have everything unbolted, it will take some convincing to get the manifold out. But trust me, it can be done, as seen below....
Once the clamp is off, slide the turbine housing and O2 housing off together, and be VERY careful not to damage the turbine blades.
You'll then need to remove the v-band clamp holding the hotside to the turbo's center section. Depending on the orientation of the clamp your's might not be as easy to get to as this...

This is what it looks like with the turbine housing out, the turbo is held securely in place by the coolant and oil hardlines...
This is your friend, use it on EVERYTHING you put back together!!
You'll need to attach the O2 housing to the Turbine housing before putting it in the car. You will need to use NEW STUDS where they were on the original hotside. The hotsides do not come with them and even if you are able to get them out of your stock hotside, chances are the threads will be destroyed. So do yourself a favor, order them ahead of time and have new ones ready.
Installation is reverse of disassembly. Total install time... 4 hours for me. Hope this gives some of you DIYer's some confidence to tackle this. Good Luck!!

EDIT: Here are the torque specs...

You're all welcome, thanks for the compliments guys...
My impressions... it sure looks nice!!! 
I havn't driven it yet, I'm driving up to TurboTrix tomorrow to have Shiv tune it, I don't wnat to drive around with a current custom tune that doesn't account for it and mess something up. I'll let everyone know the improvements after I get tuned tomorrow.
