Ok the axles should work as long as they are from a b16 powered ef (88-91) civic/crx or a 90-93 integra. Remember the integras got b16's in the xsi. As for your crossmember you can hack it up, my buddies did this on thier b16 turbo'd rex and they are now buying an aftermarket one. Inovative racing sells one for 200bucks that allows you to run the 92-95 civic half size radiator which is a great investment if your going turbo, clearence issues with the bigger full size ef radiator. The inovative crossmember is already designed to fit a turbo mani and downpipe as well. My buddys are running a bone stock b16 with a t3/t4 tuned at 7psi pushing 240hp to the front wheels.
