Mercedes-AMG M159 Forged Long Block — Race-Spec 1,500HP+ Build
The M159 is the pinnacle of AMG naturally aspirated engineering. Purpose-built for the SLS AMG with dry-sump oiling, 12.0:1 compression, forged internals from factory, and a redline north of 7,500 RPM — this is the engine that powered the SLS AMG GT3 on circuits worldwide.
YPG builds every M159 forged long block in-house with race-grade internals rated to 1,500HP+ under forced induction. Stage 2 CNC-ported heads with increased airflow. No core exchange required. This is a complete, race-ready long block — built for GT3 programs, forced-induction SLS builds, and serious track use.

What's Included — Complete Forged Long Block
This is a fully assembled long block. Block, heads, and complete forged rotating assembly — ready for ancillaries and installation. No core exchange required.
Forged Rotating Assembly
- Forged Thermal-Coated Pistons — Ceramic thermal-barrier coating on all 8 piston crowns reduces heat transfer and detonation risk under boost. Teflon-coated skirts for reduced friction and wear at sustained high RPM.
- 4340 H-Beam Forged Connecting Rods — Aircraft-grade steel, rated to 1,500HP+ cylinder pressures. Designed for forced-induction abuse and extended high-RPM operation.
- Forged Crankshaft — Balanced and blueprinted within ±1.5g
- Head Studs — 220,000 PSI rated. Mandatory for boost — eliminates head-lift under high cylinder pressures.
- Race-Grade Bearings — Tri-metal bearings specced for high-load forced-induction duty
- Balanced & Blueprinted Assembly — Every rotating component matched and balanced for smooth operation at race RPM
Stage 2 CNC-Ported Heads
Every M159 forged long block ships with Stage 2 CNC-ported cylinder heads — not a cleanup port, a full performance port job designed to move significantly more air than stock. Larger intake and exhaust runners, optimized combustion chamber geometry, and upgraded valvetrain components. The M159 already flows well from factory — Stage 2 porting pushes it into race territory.
- Increased intake and exhaust flow — measurable CFM gains across the entire RPM range
- Optimized combustion chamber — improved burn efficiency and detonation resistance
- Upgraded valve springs and retainers — rated for sustained high-RPM operation above 7,500 RPM
- 5-axis CNC machined — repeatable, consistent port work on every head
GT3 & Race Applications
The M159 powered the Mercedes-Benz SLS AMG GT3 — one of the most successful GT3 cars of its era. The YPG forged long block is built to the same philosophy: maximum reliability under sustained race conditions, with a power ceiling far beyond what the factory engine was designed for. If you're building a GT3-spec SLS, a time-attack car, or a forced-induction street monster — this is the foundation.

Frequently Asked Questions
How much does an M159 forged long block cost?
The YPG Motorsport M159 6.2L V8 forged long block with Stage 2 ported heads is $59,999. Pay in full or split 50/50 — $30,000 deposit to start, remaining balance due before shipping. Complete race-spec 1,500HP-capable build, no core exchange required.
What is the difference between the M159 and M156?
The M159 is the SLS AMG-specific variant of the 6.2L V8. Key differences: dry-sump oiling system, higher compression ratio (12.0:1 vs 11.3:1), forged internals from factory, revised intake manifold, and 563–622 HP depending on variant. The M159 was also used in the SLS AMG GT3 race car.
Is this suitable for GT3 racing?
Yes. The M159 powered the factory SLS AMG GT3 program. The YPG forged long block is built with race-grade internals, Stage 2 ported heads, and head studs — designed for sustained high-RPM operation and forced-induction abuse in GT3 and endurance applications.
Do I need a core exchange?
No. The YPG M159 forged long block ships as a complete new build with no core exchange required.
What is the build time?
Typical build time is 4–6 weeks from order. Contact YPG Motorsport for current availability and lead times.
Do you ship worldwide?
Yes. YPG Motorsport crate engines ship worldwide. Crate engines are excluded from free shipping; freight is quoted per destination.
