Supertech Block Guard for Nissan QR25DE Engine (BG-QR25DE)
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
The Supertech Block Guard for the Nissan QR25DE engine provides essential reinforcement for open-deck blocks in high-horsepower and forced-induction applications. This precision-machined component installs into the top of the block's coolant jacket to stabilize the cylinder sleeves, effectively preventing "sleeve walk" and wall failure under extreme cylinder pressures.
Engineered for maximum durability without sacrificing thermal management, the BG-QR25DE features strategically placed passages to maintain critical coolant flow to the cylinder head. It is a vital upgrade for performance builders looking to push the limits of the QR25DE platform while ensuring long-term structural integrity.
- Designed specifically for the Nissan QR25DE open-deck block
- CNC-machined for precise fitment and maximum cylinder wall support
- Minimizes cylinder wall flex and distortion under high boost or high RPM
- Maintains necessary coolant flow for proper engine temperature regulation
- Manufacturer Part Number: BG-QR25DE
