click forums, then refrence
then look for first gen crx faq
the D16A1 for a 86-87 integra will bolt in using motor mounts from both cars, as well as integra spindles and axles..
it has 113 hp for 86-87 and 118 for 88-89, but you need the vacuum advanced ditributor from the 86-87 as well as the ecu
you will also need to convert to MPFI
leaving work now but you can write me if you need more help, but def check the faq for the first gen crx for lots of cheap mods
edit: and think about getting a new car if you are planning to dump$$$ into it...
