S402 Clone build

Took some time but sourced a low mile alternator. Good to check that off the list.

Question that came up regarding tuning down the road:: the S402 headers don’t have an O2 sensor in them like USDM ones ( JDM has the O2 sensor in the downpipe-at least on mine). We can port a sensor in the headers, but the piping is already pretty skinny and the sensor would def disrupt some airflow. We’ll see soon enough. (pic is a usdm sti header then mine sans the sensor)

@WRX USA thanks for the tip- received the Killer B high flow water pump housing. They never disappoint with the quality of their gear. Love it.
