Update.
That table of bits has become a near complete turbo set up. I went with a water to air charge cooler as getting an air to air cooler was too much for my nose cone.
The boost pipework is pretty much done as is the exhaust side of things. I need to weld some bits to the radiators to mount them next before making the water pipework.
I was going to go with an external wastegate but decided to adapt the oem wastegate actuator instead.
Should be fun.
