Ok, I've got a 98 dx hatchback with about 98K. It runs nearly perfect and is clean as **** throughout. The oil never turns dark hardly at all even after 3000 miles. Well, I have a cat-back, header intake, basically all the common bolt ons. Well, I need more power. I am gonna order a Jackson supercharger for it, as well as install a d16z6 head. I also want to apply a NX nitrous kit. Wil the motor hold??? Does anyone have similar experience with a D series motor. Can anyone see problems with the head swap?? Should I prpare the block in anyway that will help. Maybe a block-guard or something similar??? Thanks for any and all input
