First off I got an civic dx hatch back. I installed a short shitfer and the car has pacesetter exhust on it but it will be trashed or sold that the only modsI can do almost anything as far a suspension and body work but i want some suggestions about power. I want to get antother engine can't afford a b sereis but I'm taking apart a d16z in school so in a few weaks i'll be able to tear down and rebuid them by heart so I would like to get rid of the TBI 4 speed and replace it with a multi port5 speed.I'm starting with body work few small rust spots but while I'm doing that I would like to swap the 4 speed to a 5 speed if possible. so will it bolt up to the stck engine? then after that what part do I need to convert the ecu, injectors resistors. then should I look for a vtec engine nonvtec Iplan on building the engine before I instll it I havn't decided should I get 10.5:1 pistons and use my old zex kit or get standard 9:1 and go "homemade" turbo set. All suggestions will help. also will civic type r piston work in a d series?
