The Gen-2 Rampage RS-450 is everything that is missing from a full bolt-on Type-R and has been designed to be the ultimate street and circuit Turbo Upgrade. It can be used with the stock engine and fuel system and under these conditions will support up to 470WHP on 93 octane. This upgrade is intended to be used without the need for port injection or a built motor, however, we do recommend Fuel System Upgrade to maximize the potential of this turbo and protect your engine. The Gen-2 RS-450 is a direct replacement for your stock turbo and can be tuned using Hondata. We have upgraded the compressor and turbine wheels to larger diameters and improved aero (details below including Dyno graphs), reduced the blade count from 12 to 9 on the turbine wheel, and anodized the billet aluminum 10 blade compressor wheel for added durability. As a part of our service to you, we ceramic coat the turbine housing to retain thermal energy, maximize efficiency, and reduce engine bay temperatures. In addition, we are including our grade 5 titanium exhaust studs as standard. A new OEM turbo to cylinder head gasket is also included for your convenience.
The approach to our design and wheel sizing was to retain as much of the factory spool characteristics and significantly open up the mid-range and top-end power band. It was also important to consider the limitations of the factory housings and size our wheel combination accordingly to get the longest life possible from an upgraded unit.

By choosing to buy the RS-450, you are not only getting a great upgrade, but you are supporting future development of our products. In return, you will be the first to be notified of new FK8 products as they are developed, giving you a chance to be one of the first to receive them at discounted pricing. If you choose to upgrade to one of our G-Series turbo kits, we will buy back your RS-450 at a reduced price. As development continues on the RS-450 and in the event that we offer a 2nd or even 3rd gen model, you will be the first to be offered the new upgrade with the buy-back option.
**At the time of purchase, you will need to select one of the core exchange options. If you plan on sending your OEM turbo in for the core exchange please select “yes”. Once we receive and inspect your turbo, a core refund of up to $800 will be processed. By selecting “no” you are opting to keep your OEM turbo and pay the full core cost of $800. For full core refunds we require a crack/damage free turbo (damage to wheels is OK, housings must be crack free for full core value). Broken, stripped, drilled studs will affect core refund amount.
