Schurkey Posted August 13, 2023 Report Share Posted August 13, 2023 (edited) First thing most folks need is a higher limit on their credit card. There's no point to twin turbos unless you're building REAL power. That means custom pistons, heavy-duty connecting rods. Aftermarket "balance" job. Maybe aftermarket main caps + align-bore. Maybe an aftermarket crankshaft. Maybe you get lucky. Cylinder head porting with expensive valves/springs/retainers/keepers/rocker arms/pushrods to handle the cylinder pressure and exhaust heat. SFI flexplate/flywheel and damper. Custom exhaust from the heads to the turbos, and from the turbos to the rear bumper. Lots of heat shielding. Many rounds of computer tuning/data recording/more computer tuning/more data recording. Transmission, and perhaps braking upgrades.
