any fan over 1900cfm's will sefice for a resonably cool location, if you live in a hot place, u might want two fans....i use a permacool fan, but there are many options, look at summit racing or something.
custom piping, unless done for a race setup, IMO looks pretty ugly, the welds and sh i t, but if u dont care about looks, then its an option...
i always suggest doing it right (even if u are a college boy), so u dont have to do it twice, ya know : )
no, you dont want to run your SR with no IC...(can u? yes, you can do anything, but u shouldnt)
I use, and will only use a full face iron clutch (clutch specialties in socal), other than that i recomment ACT, RPS, OS gilken, or HKS twin plate : )
BOV sound clips:
http://www.alltrac.net/tuning/blowoffvalve.htmli think the HKS SS bov is one of the best for performance, if your worried more about sound, i dont know what to tell you....
dont expect to pay less than 7 grand for the swap
