Ants is right, lag and no responsiveness should be a crime or atleast punishable under the anti gay laws.
It's beyond me why the hell people r so intent on makin there car run like a pig, and if people can't comprehend more lag and less bottom end power with a bigger exhaust including the size of the turbine housing then theres not much hope 4 that person really.
As R31Nismoid pointed out on the 1st page, GTR aren't much fun for anything under 140km/h and by the time it's reached you've well and truly lost ya license, so to make it even laggier defeats common sense specially 4 the street!
Why do u think the discopotato (2860rs) is so famous on an SR20 makin only 220/230rwkw...cuz that bich fries the tyres on tap all day up to fourth like it's nobodies business! rwkw on a dyno is just a final powerfigure, usually when u gain something in the top end, it means youve lost power and or torque down low, and lag is horrible!
If your goin balls deep in drag racing or racing, then yes u might consider a laggier setup for the benifit off top end performance. but Street and racing are 2 completely different things, i feel like i'm stating the obvious
Back on topic and the -7/9s either of them with e85 and cam gears is an insanely quick street car making more power then ya ever need to get to the fish n' chip shop
