i am just learning so go easy on me - i have a rsx-s and want to research a N/A build. I am curious which route would be most desirable:

k20a2 head on a k24 block with k20 crank using 6.250" rods and a 90mm overbore / 86mm stroke - all fully built etc... 1.85:1 r/s @ 2188cc

or

k20a2 head / block with stock sized rods (forged) - over bored to 90mm as well but the r/s ratio will be 1.62 @ 2188cc

i know r/s ratio isnt the only concern but which build would have the most performance / reliability - keeping in mind either route would be done properlly.

take it easy on me

 

id go with this setup: k20a2 head / block with stock sized rods (forged) - over bored to 90mm as well but the r/s ratio will be 1.62 @ 2188cc

 

i wouldnt buy a new block from honda or acura, so i would just overbore the 20 block you have and get some decent parts in the head, and better rods/pistons.

 

thanks for the reply guys

the quest for torque.........that was the reasoning behind the 2.4 block.....

anybody else have opinions??
