Definitely boost it. I had a jdm d15b on 8lbs of boost on a conservative tune and it made 210hp 154trq. Trust me you will love it and it handles up to 10lbs of boost easy AS LONG AS YOU ARE TUNED. That is the biggest factor in it. and for the price of some turbo kits around here you could get away with getting everything done right for 2k.

Plus I can sell you a P28 ECU that's already chipped and tuned for a turbo d15b on 8lbs... its my old ECU. LMK
