A 700hp+ 6.0L  LS engine owing around 6k USD powered this rather porky 4720lbs (2100kg) chassis to 2nd place in the GTT @optimabatteries Ultimate Street Car Invitational at @semashow. Build wise forged @MAHLEGroup pistons and @Lunatipower connecting rods are used along with @KingBearings engine bearings, ported LS3 head and aftermarket cams. The twin @BorgWarnerCorporate 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 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 @vikingperformance2574 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.
