I'm workin on gettin all the parts for my turbo setup on my D17. On the turbo, one side of the oil system is round and threaded, the other side is square....do i need an oil adapter for that side or what??? I'm gettin most of the other parts put together, but i still need all my oil line stuff, and i may end up havin to put in a half-radiator because it's a VERY TIGHT fit, and where did you guys run the lines to your MBC to get it inside your car? Thanks!

 

Yes, the threaded side is your feed line, and the other side, you buy an aluminum adapter, for a AN fitting, the make your return line. There are a lot of companies that make them, i've had good sucess with http://www.turbocity.com

My mbc lines run through the firewall gromet on the main wiring harness on the drivers side.
