a b16 with minor mods would light up a d16 vtec turbo, seen it a million times. Stock b16 with lightweight flywheel and header verse mostly stock d series turbo. Not to mention if you are thinking about going turbo go with a b series and it will make far more power on the same turbo setup as the d. You just have to add the price of a swap, i know this is pricey trust me. I think its worth it but plenty of others here will dissagree. Good luck.
