When the goal is four-digit horsepower, the Toyota B58 needs more than bolt-ons--it needs structural reinforcement, forged internals, and absolute control over cylinder pressure.
The VAC Motorsports 1500 Series Pro-Xtreme Turbo Build Kit is designed for builders pushing the Toyota B58 far beyond OEM limits. This kit addresses the real failure points seen in extreme boost applications: block integrity, rotating assembly strength, head lift, bearing load, and harmonic control.
This is the foundation for serious Supra builds--street, track, drag, or roll-racing--where reliability matters as much as power.
What This Kit Is Built to Do
undefined Support up to 1,500 horsepower
undefined Reinforce the B58 block for extreme boost
undefined Eliminate OEM weak points under sustained cylinder pressure
undefined Handle aggressive turbo, fuel, and RPM strategies
undefined Provide long-term durability--not just dyno numbers
