The Core Exchange Program
Your old engine, transmission or outboard powerhead still has value — trade it in. Buy a remanufactured unit from stock, send us your old core, and get the deposit refunded in full.
How the Exchange Loop Works
No waiting weeks for a rebuild of your own unit — you get a finished, dyno-tested exchange unit now, and your old core becomes next month's stock.
Buy the Exchange Unit
Order a remanufactured unit from stock. Price + refundable core deposit on one invoice.
It Ships Immediately
Crated, insured, tracked — dispatch within 48 hours. Your vehicle is down for days, not weeks.
Send Your Old Core Back
Within 60 days, in the same crate if you like. RMA number on the outside — full process on our Core Returns page.
Deposit Refunded
Inspected within 5 business days of arrival; approved refunds are paid within 14 days. Done.
Why Exchange Beats Waiting
Days, Not Weeks
A rebuild of your own unit takes 5–10 working days plus transport. An exchange unit ships within 48 hours of ordering.
Already Proven
Exchange engines are dyno-tested and documented before they hit the shelf — you receive the data sheet with the unit.
Cheaper Than New
Remanufactured exchange units typically cost 30–50% less than new — with a 12-month warranty behind them.
Circular by Design
Your core is machined, rebuilt and tested for its next life. Less scrap, less new casting, lower prices for everyone.
What You Actually Pay
Example: remanufactured V8 on exchange. The deposit leaves your account and comes straight back when your core passes inspection.
No rebuildable core to return? The deposit simply stays as part of the purchase price.

Stock rotates weekly — email us your engine code or VIN and we confirm availability and deposit the same day.

Common Questions
Exchange is faster and usually cheaper; rebuilding your own unit keeps your matching numbers and allows a fully custom spec. Daily drivers and work vehicles → exchange. Number-matching classics and custom builds → rebuild. We'll price both routes so you can decide with real numbers.
You get photos and the inspector's notes, then three options: we return the core (freight at cost), we scrap it responsibly (free), or partial credit where the unit allows. A rejected core never quietly disappears. Full criteria on the Core Returns page.
60 days from delivery of the exchange unit. That's deliberately generous — enough to swap the engine at your own pace or your installer's. After 60 days the deposit converts to a purchase.
Yes — "core-first" exchange: send your unit in, we inspect and approve it, then your exchange unit ships with no deposit charged. It adds a week versus deposit exchange, but nothing sits on your card. Ask for core-first when ordering.
Yes — workshop partners and stocking dealers get consolidated core returns (monthly shipments instead of per-unit) and net deposit accounting. Details on the Become a Dealer page or email us.
