Dear friend thank you for your responce but the head that you show us at the video is not the stock head for N21 7T. If you didn't had problems with temps why did you replaced the stock one?
Edit: just now i realised that you are talking about N21 R7. The subject of this post is a N21 7T on road engine on a rally game car
