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

Buy the Stage 2 kit if you own a Hemi Predator (60363) and want the most power without splitting the case. Buy the Stage 1 kit if you own a Non-Hemi Predator (69730) or want a simpler bolt-on. The Stage 2 adds a Mod 2 cam and a bored .650 carb for roughly 12+ HP versus about 10+ HP from the Stage 1. Both share the open air filter, jet, valve springs and aluminum flywheel, so build quality is the same. Owners report the cam is the real difference, with stronger mid-range pull.

  • Choose the Stage 1 kit if your engine is a Non-Hemi Predator 69730 or you want a quick bolt-on without a cam swap.
  • Choose the Stage 2 kit if you have a Hemi Predator 60363 and want maximum power without opening the case.

What reviewers say

NR Racing Stage 1 Speed Kit 212 Predator

Owners of Stage 1 Predator kits report a noticeable power gain and straightforward installation. The main cautions are engine compatibility and the safety of the stock flywheel.

What people mention
  • Power gainPraisedOwners say the kit wakes up the 212 and gives a real increase over stock.
  • InstallationPraisedBuyers describe the install as simple with basic tools.
  • Engine fitmentCriticisedThe kit will not fit Hemi Predator engines, and buyers warn it is easy to order the wrong version.
  • Flywheel safetyMixedThe stock cast flywheel is prone to failure, so the aluminum flywheel option matters, but choosing it drops the small fan and offset key.

Questions and answers

Which kit fits my engine?
Check the valve cover. A cast aluminum cover means Hemi 60363, so use the Stage 2. A stamped steel cover means Non-Hemi 69730, so use the Stage 1. The kits are not interchangeable.
Is the Stage 2 worth stepping up to?
Yes if you have a Hemi and want the most power without opening the case. The cam and bored carb add roughly 2 HP over the Stage 1 and give stronger mid-range pull.
Do I need an aluminum flywheel?
Yes for safety. Stock flywheels are prone to failure at higher RPM. Both kits offer an aluminum flywheel, and the Stage 2 includes one.
Can I install either kit myself?
The Stage 1 is a straightforward bolt-on. The Stage 2 adds a cam swap, which takes more time and care but still does not require splitting the case.
Do the kits include exhaust?
No. A header or exhaust is optional on both kits and sold separately. You pick kart or mini bike fitment when ordering.
