NR Racing Stage 1 Speed Kit 212 Predator vs Predator 212 Stage 2 Speed Kit

Buy the Stage 1 if you want a simple bolt-on bump in power on a stock non-Hemi Predator 212 and plan to keep the stock cam and carb. Buy the Stage 2 if you want the most power without internal engine work: it adds a Mod 2 camshaft and a bored .650" carb to the same Stage 1 parts, and the maker rates it at 12+ HP against roughly 10+ HP. The Stage 2 is the stronger kit on features, but it is the harder install because the cam goes in the block, and both kits demand an aluminum flywheel for safety. Owners of both report the open filter needs regular oiling in dirt, and neither kit fits Hemi Predators.

• Choose the Stage 1 if you want a quick top-end kit that keeps the stock cam and carb and is easy to install yourself.
• Choose the Stage 2 if you want maximum power from a stock non-Hemi block and are willing to swap the camshaft and carb.
