single for the win. one you go single you cant go back.
ive driven a few rb26,s most with twins. 2530's gtss,34n1 all were pretty good. but they felt quite lasy and were slow to boost.
ie.. they start building boost quite low but dont reach the target boost till quite late. the norm with those was 1 bar at around 4500 in a meadium loaded gear.
thats the same as my t04z. with less power from the twins.
i persomaly prefer the single. maintance is easier and it looks tough. but you kinda loose the rb26 howl at hi revs. but thts ok the external gate makes up for it
