The engine on the Cobra R and the Lightning seem to be very much alike. I was reading about the R and they said that the Cam lift was increased t 13mm on the intake and 12mm on exhaust. I don't know this for sure but dosen't the Lightning 10mm's. If so, would they be interchangable? The R also comes with bigger exhaust ports. I have heard of couple of part being interchagable such as the single bore tb. Does anyone have any feed back on this.
