BMW S63 4.4T V8 Forged Internals — Rods & Pistons Kit
The BMW S63 4.4L twin-turbo V8 is the high-output engine behind BMW's most powerful M cars — the M5 (F10/F90), M6 (F12/F13), X5 M (E70/F85/F95), X6 M (E71/F86/F96), M8 (F91/F92/F93), and Alpina B5/B7/XB7. With aggressive ECU calibration, larger turbos, downpipes, and E85 fueling, the S63 delivers massive power gains — but the factory cast internals become the weak link beyond 800HP.
YPG Motorsport's forged internals kit replaces the factory rods and pistons with forged H-beam connecting rods and forged aluminum pistons, rated for 1,500HP+ and engineered to handle sustained high-boost abuse on pump fuel or ethanol. The essential bottom-end upgrade for any serious S63 build.
What's Included
- 8x Forged H-beam connecting rods (ARP hardware)
- 8x Forged aluminum pistons with rings and wrist pins
- Balanced and matched set
Why Upgrade
- Factory cast internals are the failure point beyond 800HP
- Forged components handle higher cylinder pressure and heat under big turbo and E85 builds
- Essential for any M5/X5M pushing serious power
