For a stock-motor daily-driven truck, is a single or twin turbo kit the better value, and what do the kits cost?

For value, a single. Speedway describes single-turbo setups as generally easier to install and more budget-friendly.

	Single turbo	Twin turbo
Cost and install	Cheaper, simpler	More expensive, more complex
Response	Can spool slower, mostly down to turbo size	Two smaller turbos spool faster, smoother power curve
Engine bay	Easier to keep factory accessories	Harder to keep factory accessories

Where to save on the turbo: a cast compressor wheel instead of billet saves at least a few hundred dollars, and a journal-bearing turbo instead of ball-bearing saves a few hundred more. They spool a little slower but can still support around 700 hp at the wheels. Doing the install yourself saves the most.

On a stock engine: stock LS bottom ends have survived very high power. What matters most is a proper tune balancing air/fuel, timing and boost. Pick a horsepower goal first, then size the turbo.
