 Seeing no need to reinvent the wheel, Nathan had Dermody Diesel Performance keep things simple yet economical and effective when reinforcing the bottom end of his 2006 LBZ. Under all the Illusion Cherry powdercoated intercooler and intake plumbing, there’s a competition-prepped short-block packing an externally balanced crank, ARP main studs, Wagler forged-steel I-beam connecting rods, and cast-aluminum stock compression Mahle pistons. To ensure sufficient oil pressure is always on tap under load, a shimmed oil pump from Wagler sits in place of the factory unit, while Cen-pe-co Super High Performance engine oil circulates throughout the engine.

Fastened to the block by way of ARP 2000 head studs sit a set of Wagler-ported factory cylinder heads. In addition to being opened up on the 5-axis CNC, they were treated to Wagler’s 130-lb dual valve spring kit and 4130 chromoly pushrods. Wagler’s one-piece cast street intake is also visible here. For a little dress-up, a set of billet-aluminum upper valve covers from Socal Diesel were bolted on, along with a pair of billet fuel rails from Wagler.

 Facilitating the use of both a T4 turbocharger and the one-piece intake manifold is a twisted pedestal from Wagler. Attached to the pedestal, you’ll find a Borgwarner S366 SX-E. With both its 66 mm forged milled compressor wheel and 73 mm turbine massaged to move more air, the reworked SX-E charger builds roughly 50 psi of boost while only making 60 psi of drive pressure.
