Default Replacing the Cold side of turbo.

Does anyone see any issues that I would run into replacing the cold side of my turbo with a replacement cold side from another turbo that is in better shape? Its all the same but I will be putting in a newer one. It looks like just the Oil and Coolant lines, and clamp that attaches the cold side to the hot side. It should just slide right out. Im to lazy to pull all the exhaust apart and pull the turbo all the way out. Seems like this would be easy from the looks of it. plus I have a shit ton of room. I run the translator so i really dont have anything around the turbo, tranny area anyways.


Any issues I should know about?

Are you planning on replacing only the housing or the compressor wheel too? If the wheel is being replaced you need to have the rotating assembly balanced or the life of the Turbo will be short.

Of course to have it balanced you need to remove the whole Turbo.

Sounds like he just wants to take the v-band off and leave the exhaust housing on the manifold while replacing the rest of the turbo. So a little more than the "cold side".

I dont see why that wouldnt work. Ive taken the exhaust/o2 housing off and just left the compressor hanging there before lol.

Then again its like two nuts on the down-pipe and four bolts to pull the whole turbo... Not a big deal at all...especially if you have to pull the lines and what-not. Have fun with those.

Yep this is pretty much what i want to do, pull the vband, slide out the compressor and hotside wheel, leaving just the WG actuator and the exhaust housing. I am just going to use this turbo for about 6 months while I work on getting all the necessary parts I will need to build either my HX40 setup, or ... well I have several others in mind. lol i wanted to paint the compressor housing. Its not a big deal and when I decide and begin to purchase my final turbo kit I will have my compressor powder coated red. Similar to an APS 40 Turbo. So for the time being is there a paint durable enough to not bubble or turn pink from the heat. I don't really get that warm and fuzzy feeling from the standard engine paint at Advance Auto.
