We Finally Twin‑Turbo’d the Silverado! (FIRST START)

I've been building this Silverado for years, working out the bugs and prepping the engine bay. Today, it finally gets what we planned from day one: TWIN TURBOS. We mock up the system, relocate a few lines, weld wastegate tubes, add a block-off plate, build oil feed/drain lines, bolt the twins and manifolds—and go for FIRST START. Why twins on a Silverado? Cleaner packaging across both banks, sharper response with smaller units, and because singles are more common—we wanted to do it the clean way. These turbos are sized for 1,500 hp once the fuel, intercooler, exhaust, and injectors catch up. Next episodes: intercooler, downpipes/exhaust, injectors + fuel system, boost control, and tuning.
