it would help if you mentioned if it's a 1st or 2nd gen crx the 84-87 crx the D16 out of the 86-87 will bolt in but you need the teg trans. if you have the second gen then the 1st gen teg motor will not bolt into the car you would need a ZC motor that came out of the jdm crx and your old trans will bolt up to that one
