| NO L-fitting....you need a straight fitting to the oil pan. I'd go with a 3/8 NPT fitting or have a bung w/ a 5/8 inlet welded to your pan. I used the 3/8 npt fitting, tapped the hole, and then JB-Welded it to the pan. GOD himself couldn't remove it or make it leak! |

| also remember to tap it as high as possible to prevent restriction or backflow to the turbo |

| ...and you don't want a bunch of slack in the return line either. Just make it a gradual and kink-free connection. |

| don't worry about hte oil pan, if it leaks, repair it. you won't lose enough oil to break your car as long as you watch it. |

i dont have a braided oil return line...so just drill a 1/2 hole then tap it to 3/8'' and get a 3/8'' NPT straight fitting and JB Weld it and run the oil return line?

There are several ways to do this. The best way would be to remove the oil pan from the car and have the bung welded in. I, personally, used the method in the turbonetics instruction manual (except I used JB Weld instead of silicone)
The directions can be found here:
http://www.turboneticsinc.com/technology/index.php?section=68
It's a bit complicated to explain, but basically you punch a hole in the pan, then tap the hole using the rolled metal from the hole you punched. After that, you simply thread the fitting into the oil pan!
Download the instructions. It has photos and a more involved description (on page 18 )
Hope this helps! Oh, and make sure to heed what Ace83 said. Make SURE you tap it high enough or the oil returning from the turbo will back up in the line and bad things could happen! |

I just wanted to add..
Don't drill a 1/2" hole to tap a 3/8" fitting.
Your hole will be bigger than the tap. Use your tap as a gauge to which drill bit you'll use.. then use the tap. |

I would avoid drilling anything if the oil pan is still on the car. The shavings are going where?....straight into the oil. Plus, if you DO drill, there will be bupkis to tap anyway. :P Either use the punch...then tap, or take the oil pan OFF (which is a major pain from what I've heard) and have a fitting welded to it in the proper location.
A third option ,and perhaps what B_Real45 may be suggesting, is drilling the hole, tapping with threads to tighten, and gooping it up with JB Weld. This will work just fine as long as you remove the pan before drilling! |

Yep - and that's what I'll be doing..
I'll use the punch provided, tap the hole, then for extra precaution, JB weld that mofo. |
