this depends on what model and what year crx your friend has as power ranged for the 88-91 crx from 62hp - 108hp...the d15b7 is not powerhouse but will be an improvement over the dx is what i'm assuming you have as you mentioned you need to swap over to mpfi and the dx crx (92 hp) is the only 2g that did not have mpfi
so expect a 10hp increase max but improvement across the whole rev band
