Starting to Like 3rd Gen Teg's!!

O.K. guys recently I being starting to like the 3rd Gen Integra's from 94-2001 I was wondering If I we're to buy a Integra for let's say 3,000 or so with a good body and interior would I be able to swap a Prelude Heart into it?? i mean a "h22" or would I be very off paying 5-7k for a nice GSR???

by the way I'm Lucky enough to live in L.A. and c nice Integra's for 3,00 all the time and I can find a GSR for under 7k pretty quick....
