i was wondering if i could put a 98EXd16y8 head Vtec on a 99 DX D16y7?

 

definately, its called a mini me swap, do some searching on the net, plenty of info. its about a $500 setup depending on what you can get and how available it is. i can get it done for less than $200 bc of the junk yard 20 minutes from me.
