This is a far off thing but im just interested in how my car would run with a twin setup, its a 2.2litre rb20 Redtop NICS. Its currently running a apexi ax53b70 which can also b used in a twin setup, if i was to put another of the same turbo on the engine wot would the end result be? its a 2.2 so its got abit more to give the turbos but i also heard that the nics has a 12port heard so its got better flow...? if any1 has got anything productive to add id like to hear it... im currently looking into a gt3037s but i dno a twin rb20 would b kool if it actualy worked
