hx is not worth turboing. id rather boost a dx than that. its made for economy and good gas milage and s**t. its not made for power. id drop a y8 in there...OR you could put a y8 head-intake manifold-and ecu, maybe the trans if they are different, and have a d16y8....kinda. my friend made a turbo kit for 800 bucks. its better than the drag and greddy kits. the drag manifold suck d**k, the wastegate is not properly positioned and they are known to crack easily. the greddy kits are gay cuz they use mitsu turbos which dont have a "other turbo" friendly bolt pattern....(t3 friendly is what im saying) SO if you want to upgrade your greddy kit with a t3 turbo, you need a new dp and manifold...
