This is the HPI Nitro RS4 RTR 3 EVO+ Honda NSX GT Touring Car. The Plus means more option parts have been added as standard equipment. What's new? An aluminum tuned pipe is now included for blistering speed, improved heat dissipation, and extra strength. The black alloy pipe matches the header and engine head perfectly for a stealth look that warns your buddies that the T3.0 is serious about laying down massive power. A new Two Stage air filter has also been added, similar to the proven design found on the Savage truck. It's bigger than the old filter so you can run longer between routine maintenance intervals. The internal pre-oiled foam element is protected by an outer foam layer, providing optimal air filtration for longer engine life. To help put this new found horsepower to the ground, hardened metal final drive gears from the EVO SS have been added, with a higher gear ratio for more top speed and extra toughness. Our brand new powerful T3.0 engine is included. The T3.0 is a high torque engine with features that include aggressive porting, durable ABC construction, a large heat sink head, dual needle 6.5mm carburetor and a lightweight aluminum connecting rod. The large .18 cubic inch size propels the Nitro RS4 3 EVO+ to a top speed in excess of 50mph! And, the T3.0 engine is designed to be easy to start, easy to tune, and rock-steady reliable. It's equipped with the easy to use HPI Roto-Start system and, for racing applications, can be set up for bump starting. A high flow tube header and dual chamber aluminum tuned pipe are mated to revised gearing making the Nitro RS4 3 EVO+ one of the most powerful RTR 1/10 scale production cars ever!

The Nitro RS4 3 EVO+ has many of the features found on our popular RTR Nitro RS4 3, making it a great kit for parking lot drivers. The tough shaft drive system keeps the drivetrain running smoothly even in parking lots that aren't completely free of rocks. The enclosed receiver/battery box and removable radio tray keep the electronics protected from the elements and make clean-up a snap. A stiff purple anodized aluminum 2.5mm chassis prevents flex for consistent handling and extra durability. An adjustable 2 speed transmission is included, compatible with a wide variety of optional gears to help tune the gearing to track conditions. Everything combined gives the Nitro RS4 3 EVO+ a healthy dose of bottom end punch and screaming top end performance, and the durability to handle parking lot conditions with ease. To top everything off we five body styles for this exciting update of the EVO 3 line, the HPI Impreza, 1966 Ford Mustang GT, 1970 Plymouth AAR Cuda, Acura NSX, and the Greddy Nissan 350Z. Of course the bodies are completely painted with pre-applied graphics and they're exact fully licensed replicas of the real cars.
