Used or reconditioned?
For Groups 1, 2, 3, 4, and 5 (C63, E63, GLC63, G63, GLE63), used units are available from a growing donor parc as early AMG 63 vehicles enter replacement age, offering strong value for these higher-volume applications. For Groups 6, 7, 8, and 9 (S63, AMG GT 4-Door, AMG GT 2-door, SL63), reconditioned units are more commonly selected given the lower production volumes, higher vehicle values, and thinner used supply. The M177/M178 4.0-litre twin-turbo V8 is a high-performance engine where the turbochargers are mounted within the cylinder Vee. At higher mileages or under sustained performance use, turbocharger wear and associated heat-management components can reach a point where in-car repair is uneconomical relative to a prepared replacement unit. Every unit we supply has the turbochargers inspected for shaft play and boost response, the timing chain assembly checked, and the direct-injection fuel system verified before dispatch.
M177/M178 Engine Buying FAQs
Answers to common fitment, condition, warranty and delivery questions.
A:Mercedes-AMG C63 (W205), E63 (W213), GLC63 (X253), G63 (W463), GLE63 (W167), S63 (W222 facelift), AMG GT 4-Door (X290), AMG GT 2-door (R190/C190), and SL63 (R232). Covers all "63" and AMG GT variants from 2015 to present.
A:M177 is used in all AMG 63 saloon, estate, SUV, and coupé applications. M178 is used exclusively in the AMG GT 2-door sports car, which has a transaxle layout (rear-mounted gearbox). Both share identical base architecture (4.0L 90° V8, hot-Vee twin-turbo). The transaxle difference affects sump profile and mounting points only.
A:Used units suit the higher-volume AMG 63 applications (C63, E63, GLC63, G63, GLE63) where donor supply is growing. Reconditioned units are recommended for the lower-volume applications (S63, AMG GT 4-Door, AMG GT 2-door, SL63) where verified used supply is very thin and vehicle values justify the investment.
A:Use the registration checker on each listing page, cross-reference your V5C chassis code against the listing's stated application range, and confirm the engine code stamp (M177 or M178) on your existing unit matches. Contact for a free compatibility check if uncertain. AMG vehicles have specific build-sheet options that may affect ancillary fitment.
A:All units carry a 6–12 month warranty (condition-dependent). UK nationwide palletised delivery with AMG-appropriate crating. Every unit is tested before dispatch including boost pressure verification. Free pre-purchase compatibility verification included.
