I dropped the whole up pipe assembly in as a unit with the exhaust housing, turbo elbow, y pipe and up pipe as one piece. Loosely bolted the y pipe to the exhaust manifold and then attached the oil drain with the 3/8 mod to the chra and loosely bolted that to the intake. Slid the exhaust housing onto that and bolted it together

Once the housing was attached to the chra, I tightened up the drain to the intake, then torqued the y pipe to the exhaust manifold. I did it this way because I was going to clock the housings anyways to set this turbo up for intercooling and it’s the best way to get no leaks the first time.
Then I started assembling the compressor housing. With the housing clocked for intercooling, the outlet for the wastegate hits the housing so I drilled out the spot welds clock it and reweld it.
