[98hxman]

hi all. so im new to ecomoding but am well on my way with my new build. im working on a 98 civic hx with a 5 speed. im building a engine for it and trans hoping to see 40 to 45 avg mpg. how it sits now is stock 300k+ with a few bolt on mods. what im building is a modified d16y5. i have a rebuilt d16y5 head. a d16y8 block that was bored .50 over. .50 over bore d16y8 pistions and d16z6 oem rods. a d16y5 crank and oem honda bearings. the head was shaved .006 to straten it. the head gasket is a bismoto single layer gasket thats .009 thick.all this is going to put me at 10.49 to 1 compression. i plan to use a oem 99-00 y8 exhaust manifold to help build mid range torque and a d16y5 intake manifold port matched with a integra gsr 65 mm throttle body . i want to use a s20 ex transmission with the 4.25 final drive that will put me at around 2600 rpm at 60mph and 2800 rpm at 70mph. this is ideal range for lean burn and the engine lode will be low also so the engine shuld be able to mantain lean burn with ease. im planing to up grade my injectors to the bosh ev1 style. the same 185 cc rating to help with air fuel mixing. im using a msd blaster ss coil on the car now for stronger spark.i am using a cat with the y8 manifold and a 2.25 mid pipe and oem 09 civic si muffler. tell me what you guys think shuld be fun lol.
