This is not a "parts bundle."
This is a survival kit for B58 engines pushed into territory where stock architecture simply gives up.
The VAC Motorsports 1500 Series Pro-Xtreme Turbo Build Kit is engineered for builders chasing extreme boost, sustained cylinder pressure, and reliable four-digit horsepower. Every component in this kit was selected to solve the real failure points of high-output B58 engines--block integrity, rotating assembly strength, fastener retention, and thermal control.
Street car. Track car. Drag car.
If your target is up to 1,500 horsepower, this is the foundation you start with.
