Can i hook up my oil feed line to the turbo to that as well??
Here's how I have mine. It was set up for both the sending unit and future feed line (thus the cap on the one end). I never went turbo, but I would suggest, if you're going to do both, for ease of future access and to prevent vibration-related failures, you install a barb fitting into the block and then run a feed line up to a junction box somewhere on the firewall where you can better reach it. Then you can tap your feed and gauge off that block.
Thats a great idea, as for the junction box itself, would it be almost like that oil filter adapter, but without being hooked up the oil filter??
