PARTS NEEDED TO CONVERT ETK TO NTK + FACTORY ETK UPGRADES...

Converting an ETK to NTK is easy, the most important thing you need is the Nitro TK delrin tranny gear set, next the factory Nitro TK spur gear or most other 65 tooth 24 pitch 8scale spur gears with work also , the Nitro TK brake gear assembly and finaly the motor/servo mounts, which other 8scale mounts will work also. After that most 8scale fuel tank, engine and pipe combos can be used.

Upgrading your ETK with 4 better parts from the NTK would be to use... the Nitro TK high impact nylon body mounts, (much more flexible than the ETK plastic mounts), again the Nitro TK delrin tranny gear set (which is much stronger than the ETK regular plastic gears), the Nitro TK tranny case, (which is made of a much stronger nylon plastic than the ETK has) and finaly the Nitro TK axle upgrade kit, (which has bigger/thicker axles, hubs, hexes than the ETK).
