which is better
 

k, heres my problem.. i have a d16y7 that im putting in my 92 civic... i have a couple of choices
1. i could but the whole top end off my d15b7 on it and basicly it would be a plug and play setup...my question is if i do this ... would this raise or lower compression?
2.i have a complete top end off my very first motor which is a d16z6...plus ecu..its a little drity but i can clean it up.. same question... will this raise or lower my compression... (i really dont think it would)
3.i can also just change my intake on my new y7 and put a obd1 dizzy in it...

which would be better too do?
