LOJ Innovations did my LS swap. IT was ALOT more than $8k because I got my motor COMPLETELY rebuilt (6.0L LQ9 iron block), heads/cam, new pistons, rods, ARP bolts, head studs, mains, Aluminum driveshaft, UD pulley, longtubes, dual 3" exhaust, dual custom intake, ported FAST 102 manifold, 102 TB, 100mm MAF, Custom mishimoto rad setup, oil cooler, power steering cooler, Akebono 2 piece front and rear BBK from Z1 motorsports, full powertrix suspension, ES bushings everywhere, fender braces, customer grounding kit, battery relocated to trunk, Quaife LSD with 350z 3.58 diff, Wheels/tires.......so for a BASIC BASIC swap for $8k that cheap. I would assume stock exhaust, stock manifolds....EVERYTHING STOCK.
