Get the what, how and why on the 6.0L LS powered Nissan Frontier, aka Navara from owner/builder Stephen Dorrick of LOJ Conversions .
A 700hp+ 6.0L LS engine owing around 6k USD powered this rather porky 4720lbs (2100kg) chassis to 2nd place in the GTT Optima Ultimate Street Car Invitational at SEMA. Build wise forged Mahle Pisons and Lunati rods are used along with King Bearings, ported LS3 head and aftermarket cams. The BorgWarner Airwerks S257 SX-E run around 13psi but there is room to go up to 20psi on occasion thanks in part to the use of an E50 flavoured ethanol fuel blend.
A Haltech Elite 2500 manages the engine with an I/O expander to increase sensor inputs for a well set up and nicely prioritised engine protection strategy. This Nissan is AWD with the use of a TR6060 mated to a transfer case (NP120?) from a Chevy Blazer which gave Stephen an easier job of using the likes of a Y62 Patrol rear diff with that rear end seeing 70% of the torque split.
The LS retains a wet sump, however it has been modified and an Accusump is fitted for extra insurance and with essentially only Viking Berserker coil-overs fitted there are plans to upgrade much of the suspension components in the future to remove excess compliance as well as a focus on weight reduction.
