k24 bottom end on k20a EP3

8200 rpm on stock k24a3 bottom end here , will push it to 8500 rpm soon
BC cams , valve springs , retainers.

K24A will produce more torque for sure compared to k20a
But JDM K20A is a good motor already

i dunno about the ep3's, but i know with the dc5's you'll experience header clearing issues even with the ep3's swaybar...

yeah, what he said. i wouldnt bother doing the bottem end swap. Your K20 has heaps of potential. the money u put into getting the frank k24 done would be well of a waste, when u can put all that money into your k20 and you'll get some pretty decent power.

GL with your build.

turbo charge ! :p loool
saw 1 in uk magazine.. 10 psi pulling healthy 300 hp .. yuum and been running for the past 3 years.. still stroong :|

depends its a win lose situation.. stock for stock
k24 = torque with no revs
k20 = less torque with all revs

no point unless building crazy allmotor styles
