How much more does the jdm f20b accord type-R motor weigh than the usdm d16z6? If not to much more weight (for auto-x reasons) then there relativly cheap. I want to run honda 954 itbs with a full exhaust. already high compression, hondata s200 program and have some fun. If to heavy though i want a jdm d16 with arias 11.4 c/r pistons and honda 954 itbs with the hondata s200 program on my p28 ecu. Long post i know but any help on the actual weight numbers would be grealty appreciated. By the way its going into a 93 del sol si, soon with cusco or tanabe coilovers on falken azenis
