Here is an idea. 1st try to talk the seller down to about 850-900... then when you get future funds (i.e. tax return, paycheck...etc.) tyr to build up as much as possible.... BUT keep in mind the integra and the civic/crx... are based off of the same type of platform.sooooooo some of the parts are interchangeable.... seats ,lug pattern, also lets just say GOD FORBID that you get in a accident in the INTEGRA on your way to work or something like that... you can do a engine swap....and while the engine is out( BUILD THE FUKN SHIT OUT OF IT) even if you done go for the franken motor(LS/VTEC) you can still build a engine that would be able to hold an ass load of power capable of boost..(EDILEBROCK,GREDDY,HKS..... even if youu dont decide on a name brand turbo setup YOU can still go with an off brand and SAVE some cheese..) ..
Or even if you dont have a lot of cash just upgrade the valve train and clutch(well worth it) .. just think about---A CRX with a LS swap teh redines at 8.5-9 and is capable of boost....BUT like I said B4 god forbid that you get in a wreck.... that is a option that you have...

but that is my OPINION..
