i have a tubular exhaust manifold with a t3 garrett setup and was planning on using a 2.5" downpipe as well as 2.5" charge and intercooler piping. it seems as if i will definitely loose a/c but i was wondering if anyone has insight on whether i may need to use a civic half radiator and fan or if just trimming the fan shroud will probably suffice. thanks

 

would a half radiator keep it cool enough? if so would the use of "water wetter" or something of that nature help? lower temp. thermostat?

 

Get a Koyo, Fluidyne or PWR radiator and you will be fine. Benson sleeved my block using an open deck so I doubt I will have any heat issues. As long as your setup isn't having any cooling issues to begin with you should be ok.
