Why Buy a Used Mitsubishi Engine from Auto Power Source
Mitsubishi builds some of the most resilient engines on the road — the 4G63T turbo four powered Lancer Evo VIII–IX rally cars to multiple WRC titles, while the 6G72 V6 has logged decades of service under Galant, 3000GT, Montero and Diamante hoods. We have spent over a decade sourcing quality Mitsubishi engines from carefully vetted suppliers across North America. Our 555+ verified Mitsubishi engines span every major Mitsubishi family — from the high-volume 4G64 and 4G69 in Galant and Outlander, to the 6G72/6G74/6G75 V6 family in Eclipse, Montero and Endeavor, to the enthusiast-favourite 4G63T Evo and 4B11T platforms. Every Mitsubishi engine we sell has been pulled from a low-mileage donor vehicle, cataloged by VIN, and held in our climate-controlled warehouse pending sale.
Each unit went through our six-step inspection — VIN-matching, ASE testing, noise & smoke verification, full visual inspection, multi-angle photography, and palletized shipping. Our ASE-certified technicians do the testing; rejected units never reach the buyer. Mitsubishi engine-code segmentation matters: a 4G63T from an Eclipse GSX is not interchangeable with the 4B11T from an Evo X, the 6G72 ships in both SOHC and DOHC heads, and MIVEC vs non-MIVEC 2.4L blocks have different harnesses and valve covers. VIN-matching is therefore essential, and it is the very first step we run on every Mitsubishi order.
You pay a fraction of dealer-new pricing for identical Mitsubishi engineering, ship free on a heavy-duty pallet anywhere in the continental U.S., and get 30 days from delivery to return for any reason — no restocking fees. Up to a 3-year warranty covers you if anything goes wrong after install. Across 46,000+ engines + transmissions shipped, we have a 0% fitment-related return rate.

Mitsubishi Engine Buying Guide
Five things to verify before buying a used Mitsubishi engine:
-
Match the engine code by VIN — Mitsubishi VINs encode engine differently than Honda. Check the 8th digit of the VIN and consult our team. A "G" in some positions points to 4G63 family, but accurate matching takes the full VIN; text it to us and we will identify the exact code.
-
4G63T vs 4B11T — different platforms. Evo VIII/IX (4G63T) and Evo X (4B11T) are NOT interchangeable — different bore spacing, mounts, engine bay, ECU, and accessory drive. Confirm which generation Evo you have before ordering.
-
6G72 SOHC vs DOHC — verify cam config. Galant V6 was sold with both SOHC 12-valve and DOHC 24-valve 6G72 heads; the transmission bellhousing matches both, but cam timing, intake manifolds and ECU calibration differ. Confirm valvetrain before ordering.
-
MIVEC vs non-MIVEC. 4G69 has MIVEC variable valve timing; 4G64 does not. Different valve covers, different harness routing, different oil-pressure feed at the head. They are not drop-in replacements for each other.
-
Pajero/Montero diesel never officially imported to US. If you are shopping for a Montero engine in North America, you want gasoline 6G72/6G74/6G75. Diesel Pajero engines (4M40, 4M41) require grey-market sourcing and emissions paperwork that varies by state.
Our ASE-certified technicians verify every one of these points against your VIN before any engine ships.
