hondas k series engine

[thisisntjared]

this is worthy of posting because of its efficiency.

as most know honda developed their relatively new series of dohc 4 cylinders to replace the b series. these are call the k series: k20a2 in the rsx-s, k20a3 in the ep3 civic si and rsx, the k20z1 in the new civic si, the k24 in the tsx as well as other variants that are in the odessy, element, crv, some accords, etc

i dont now enough about the motor to really get into specifics but thats what this thread is for.

to start off with bragging right, a friend of mine, who probably wishes to remain anonymous for the sake of theives, finished putting a k20a2(rsx-s) motor into his 92-95 civic cx. he decided to maintain the full interior and to keep the car 100% street legal with the only power mods being an intake, header, exhaust, and chip.

he went to they dyno for the final tuning on the setup and jeff evans was able to fine to the motor to 230whp with a torque curve that is flat as a small lake with a 2mph wind.

anyway, to what you guys care about, he has been in the neighborhood of 30mpg. the only driving he does in this car is to the track and at the track for drag and auto-x racing. so thats driving 30 miles, racing then driving the 30 miles again. he races in street mod and does pretty well considering he will not use r-comps and usually places somewhere in the top three of his class, and all the others who beat him are supercharged m3s on r-comps. even other supercharged and turbo cars on r-comps fall short of what he and the car can do on street tires.

his best quarter mile run was a 12.6 and yes, again, on street tires. the tires that were on the car as he was driving there.

now i dont know what you guys are thinking but i think such an avid performer that still maintains 30mpg of combined driving, thats pretty amazingly efficient. by combined i mean race and street, not city and highway.
