im swapping my d16z6 motor for jdm d15b i heard everything jsut swaps over. i was reading something about trouble hooking up the vtech or somethin let me know if anyone can tell if i gonna have to change anything and will my greddy turbo kit and i was wondering if will fit on the d15b

 

turbo setup will fit fine, you will just have to get it tuned if you are keeping the p28, and you will have to wire 1-wire vtec.
