So I basically got a k24a4 for free when I traded a buddy some steelies with good tires for winter. He said that he believes it spun a bearing but regardless I want to do a complete tear down and rebuild. I know that this is the weaker k24 160hp and tq but i would really like to do an all motor build.

I have some general questions in obtaining my 250+whp NA build. I want to stick with the k24 head, NO K20 head swap. So here are a few questions i have on the build.

1) For my hp goals is there any specific pistons or compression i should be shooting for? I know I can buy about any piston size and ratio but don't know what would do best.

2) I plan on getting skunk2 valve train and stage 2 cams, is there anything else that I should do to the head? Full port and Polish? Milling it at all? 3 angle valve job?

3) Intake manifold choices. PRB is the most common but i think i read an article that said the jdm civic type r was better. RRC? Any opinoins for the goals I have?

The reason I ask is I have never fully built an engine from ground up. This is my first time. Between the 27 cars I've owned I have never kept one long enough to devote so much effort and time but the EP was on my list of dream cars so this build for me is a must. Any info would be greatly appreciated. Love the site and everyone here so far. Great community we have going 8) Thanks for any imput!

NA power doesn't come easy or cheap. Plan on all of the above. But since your having to go with high comp pistons (changing em out anyways) why no a2 head? You could then run a2 cams on vtec killer or locked pin vtec set ups. Look into the kMOD crate engines with the HP rating your looking for and figure your parts list has to be similar.

I will have to look up kmod k24a2 Maybe but No k20 head for me.
