cheers guys , i know what i want to do with the car (r34) , i'm looking for the best street track setup for the least $$ , i'm not looking for peak power , more good/strong midrange , watching simonR32's vids though it looks like the t67 is pretty good for the size, the next killer is i'm going to be running it on 98ron fuel (daily driver) so it will be sub 300rwk either way . i do have another project i was planning on putting a t67 on , so i could just try it on the 25 first (yes i'm talking myself into it lol)
