I also try to put .15 OS engine on FW05, and work fine. Execpt the engine and Pipe, other part are factory build.
But I feel my car with .18 OS enigne, the clutch maybe need to change to Centex type or other, becasue I cant set the clutch for "台" 速 even I change the spring stronger. Maybe power of this engine is higher......(I dont know just guess).
For the pipe, Whihc brand and model is suitable for my OS 18 CVR enigne? How much?
