Frequently Asked Questions
Q: Can I run these on a stock turbo?
A: Not recommended. 250% over injectors require substantial airflow—use upgraded single or compound turbos.
Q: Do I need a lift pump and CP3 upgrade?
A: Yes. Stable supply pressure and adequate high-pressure fuel are critical at this flow level. See our lift pumps and the Exergy lineup for CP3 solutions.
Q: Are these truly flow-matched?
A: Yes—Exergy individually balances and matches each set and provides documentation.
Q: Is there a core charge?
A: Many reman sets carry a refundable core charge. If applicable, you’ll see details in the product options or at checkout.
Q: Streetable?
A: With proper air and tuning, yes—but these are competition-oriented. Expect aggressive fueling behavior.
