hello everyone my name is Lev and im in sydney australia.
i found this forum through
www.ausrotary.com and its very interesting, ive read through quite a few threads but havent found quite what i'm after regarding my situation.
ok i have a s3 rx7 with a 12a turbo engine, its reasonably modified with more injectors a fmic, aftermarket ecu, bigger turbo, ive purchased a pre turbo water injection kit brand name CAPA, now i dont like having a fmic for a few reasons, less air flow to the radiator, makes my car look modified i like the stock look, lots of piping which i assume means added lag.
my question is, if i get a small top mount intercooler like on later rx7's together with the pre-turbo water injection am i likely too see any improvement? im not so sure because i think the stock piping on those intercoolers is 2inch and my whole intercooler setup atm is 2.5 and also the intercooler is alot smaller however im not sure if thats a large factor because ive read on here that water injection can even be used without an intercooler. or would the engine heat just rewarm my air through the "cooling fins" due to it being top mounted lol.
any suggestions are much appreciated
thanks
