The os .18cv-rx is a direct replacement for the rs4. But you also need the 20mm engine mount which is an HPI part#. i can't remember the # but if you look up that engine on tower hobbies down at the bottom of the page will list the mount you need for that engine and its like $25 and the engine is $149 on tower hobbies as well.
