Thank You for Your Order!

We appreciate you choosing a SneedSpeed Engine. Each engine is built to deliver maximum reliability, power, and longevity. To ensure proper lubrication, seating, and break-in, please follow the installation and break-in procedure below carefully.

Engine Installation & Break-In Procedure

Use 5W-40 conventional or semi-conventional engine oil for initial startup.
Install engine completely before adding fluids.
Remove coil packs and spin engine with the starter to prime the oil pump and internal passages.
Once oil reaches the top of the engine (visible under the valve cover), reinstall the coil packs.
Start the engine and allow it to idle briefly, then hold RPM at approximately 2500 for 15–30 seconds before returning to idle.
Let the engine reach full operating temperature, then shut down and inspect for leaks.

Test Drive & Break-In

Begin with a 3rd gear pull at 75% throttle from 2500 to 4000 RPM, then let the engine decelerate back down to 2500 RPM in gear.
If everything looks and sounds good, repeat with full throttle pulls at 2500–4500 RPM, 2500–5500 RPM, and 2500–6500 RPM — allowing the engine to pull back down each time.
After these pulls, drive normally for 5–10 minutes to help the engine cool evenly.
Return to the shop, inspect for leaks, and change oil if desired.
Your engine is now broken in and ready for use on track or street.
Change oil within 500 miles or before your first track day.

⚙️ Pro Tip: We recommend Motul 5W-40 8100 series for street applications and Motul 300V series for track use. Proper oil choice ensures ideal protection and performance for your build.
