i want to upgrade my 1914 with a turbo..... the engine currently has an Fk45.... can i use this cam for a turbo application?? i dont want to have to change the cam

if im correct the Engle ad states that the "new FK-40 series profiles can be used for normal aspirated engines to turbo, blown, or nitrous oxide applications" is this true of my FK45 cam?

if so what size turbo should i use on my 1914 with 40x35.5 heads? header tube size?? i plan on using either a 40 or 44 sidedraft.
