Alright, ive got a set of Nismo Lemans running on my 32, on my last tune the Lemans turbos made 130rwkw at 4500 rpm (this is when the power starts to come on hard, 130rwkw doesnt sound like much i know but by 6000rpm it makes 280rwkw), But for turbo Lag argument sake we'll start at 4500rpm.
compare that with the GT2530 which correct me if im wrong are just the HKS version of garret -5 and are still a resonably decent turbo. According to this graph i found which is based on engine KW's, the 2530s (-5s) make 200 engine kw, which would be what 150rwkw at most?
Now everyones goin to ask what mods i have and what mods the turbos on the graph have . I would assume that as the 2530s (or -5s) are making 601hp and their max combined output is 640ps, they're pretty much at the limit of what they can do and have the correct supporting mods. (dont forget the lemans are rated to 640ps as well so theres not goin to be any top end lost over the 2530's)
Meanwhile on my Lemans turbo set up, i made that power and ive got only a 3 1/2 exhaust with 3 inch dumps with a rubbish set off front pipes, while still running standard cam gears and cams.
I really dont think the lemans are as rubbish as everyone makes them out to be, a bit laggy yes but still a heap of fun. Im sure someone is goin to try shoot me down but meh
will try and get a before and after graph of when i do have front pipes and cam/cam gears instaled... will be soon
BTW if u want -5s GCG do them for about 2 grand if i remember correctly.. dunno if they come with actuators though
cheers
