You need to swap the tranny with the new motor along with the ECU. The B16 is a good choice. That should give you around the same power if not more than a turbo D15 but with much more reliability and drivability.
Good luck.
yup all true. higher compression sucks for boost, but if you invest in some good fuel management and dyno tuning you should be set. also, new headgasket and arp headstuds help along wth having the surfaces of the head and block checked. that will help keep you from blowing any headgaskets if you decide to boost.
if you can afford the swap go for it. its obviously better than swapping a d16y8, but will cost a lot more. another downside, B's really lack in torque.. but a turbo would fix that up nicely
i've got the boost bug sorry, haha. in my mind boost will fix everything.
