LS3 and up oil line adapter for Moroso oil pans for 2004-2006 GTO

  • $ 13000

I've owned my 2004 GTO since 2005.  As of 2018, I'm on my 5th engine with less than 60k miles on the car.  Building engines is a hobby of mine, and I use my stuff as a test bed for potential products.

421 cubic inch LSX and a Whipple 3.0L supercharger.


2005 GTO track car.  427 Dart LS Next fitted with an 8.3L Whipple supercharger.  Methanol fed and estimated to make almost 2,000hp (flywheel)


The oil line adapter we make is born out of necessity after discovering that the original supplied by Moroso with their oil pan is almost useless.

The LRI adapter is designed for relocating the oil filter to a more usable location when fitted with the aftermarket Moroso pan. (PN 710-20146).   It is threaded to accept standard -10 AN ORB type fittings.  (7/8-14 internal thread) We suggest Aeromotive #027-15608 fittings as they are very good quality.

This adapter is designed to clear the hardlines on the power steering rack with OEM or lowered engine mounts.  The part is made with a state-of-the-art 5-axis CNC mill using 6061 T651 AL bar stock.  Hardware and O rings are included.
