what i was really asking is like if it doesnt have a rev limiter will it go up to 13 or 14k rpms? and how can you port them? remember im new so dont make fun of me lol I would really like to sell my crx and my supra and buy an rx7 which is the best year? i would like to buy a n/a one and then go all motor (i think like that porting thing your talking about lol)
You'll need a lot of work done to get it up to 13k without tearing it apart.(and without it being totally pointless) if you're going that high it better be a full race motor with peripheral ports and it's going to cost you some cash to do it.
The S5 NA motors make more power because they have higher compression rotors and the VDI intake. They're harder to find though and certain parts are more expensive.
