ok.. first.. the lsvtec (properly tuned) makes more power. the problems are that most people dont tune them, they throw a gsr or b16 ecu in and call it a day. another problem is the rod/stroke ratio of the ls isnt ideal to be taken to 8200rpm.. where the power of the vtec head is.































lsvtec might make a wee bit more power than a gsr when done right.. but the reliability of the gsr makes the gsr the better choice.
