ok i just got paid this friday and have about 250 to spend.
i was thinking about this .
turbo pipe (http://cgi.ebay.com/ebaymotors/95-99-MITSUBISHI-ECLIPSE-TURBO-GSX-GST-AIR-INTAKE-96-97_W0QQitemZ7996549024QQcategoryZ38634QQrdZ1QQcmdZ ViewItem)
about this one i can only see the connectors for 3 hoses, i think it's BOV, and other 2, but i don't see the one that goes to the stock boost controller,, so my question is do they come with all 4 connectors like the stock pipe?
and this . , but i don't know if i'm gonna need a O2 sensor,
a/f gauge (http://www.cardomain.com/item/ATM4375)

boost gauge (http://www.cardomain.com/item/ATM5703)
i wanna add a 3rd gauge but i don't know which one to choose, any opinions would help
i was thinking about getting a FIPK. but maybe next paycheck, but let me know what you think about this things,
wait i almost forget, a MBC i found this one
MBC (http://cgi.ebay.com/ebaymotors/PTI-MANUAL-BOOST-CONTROLLER-MBC-ECLIPSE-GST-WRX-GSX-EVO_W0QQitemZ7994958790QQcategoryZ33742QQrdZ1QQcmd ZViewItem)

"and this . , but i don't know if i'm gonna need a O2 sensor,"

You should have one. Unless your talking about a wideband O2. It works fine with the stock O2s

That MBC looks kinda cheap in my book. I would know a good one if it hit me in the head and said "Hey look!! Im a good MBC!!" but I think it looks cheap.

If you just get a a/f gauge all it will say is lean then rich it's pretty much useless unless its wideband, I'd say go with boost, oil pressure, and egt, but thats up to you. The mbc looks (and probably is) homemade just be careful if you get it and it will probably leak.

lol thats the mbc I bought!! works good but just get ready for a shit load of adjusting. It was especially hard to get it just right on my evoIII. Also I was only able to adjust from a 10 and up psi range, wouldn't let me adjust lower than that, But its nice though for that cheap
