I think you need to listen more and talk less bud. I am currently building an rb25 with the works. Major head work, cams, Forged, blueprinted, cryoed and balanced bottom end, fuel delivery system inc, plenum q45, dual feed rail, surge setup, 700 injectors . Himount, ext gate, etc etc etc. I am not bragging here, just trying to let you know that my homework has led me to believe that a 35/40 may even be too laggy for this setup.
I had the pleasure of driving a well sorted stage 3 slide hiflow setup with the minimum mods required to extract maximum efficiency and let me tell you, If i werent going drag racing that outfit would suit me to a tee. the low/midrange pull on a standard engine is bloody awesome and will have no probs taking care of any street action you are likely to encounter.
