The downpipes and turbos are loosely attached... | 
...via the ARP bolts to allow manipulation. |
Since the four turbo bolt holes are not threaded, the 3/8-inch ARP bolts go in through the bottom with the heads facing downward. | 
Each turbo is connected to the downpipe with 10mm ARP hardware. |
To lubricate the two 50-series turbos,... | 
...extra feed and return oil lines had to be routed and tapped into the oil pan. |
The necessary stainless steel braided lines and fittings are provided in the kit. | 
To finish the hot parts, John and Tony connect the Y-pipe to the aftermarket cat and downpipes. |
A 1/2-inch wrench is used to bolt down the wastegates. As previously mentioned, these Turbonetics wastegates will be replaced by TiAl 38mm units in the production kit. For the purposes of our test, they shouldn't alter the results. | |
