I've gotta say even tho I feel such a n00b when I ask this.. I know 9 is low compression, and 11 is high. What about 10? Is 10 a good number to get a turbo charge?
So it's boostable without risking anything?
Compression ratio is increased as you boost. somewhere i have a chart, but can't find it,DAPineapples said:
anyway, the higher the boost you want to run,the lower the compression ration (NA) has to be.
An example,if i remember right, is 9 to 1 at 8 psi = 11.5 to 1, so if you turbo an 11 to 1 = BOOM

Differences between k20a's.
DC5 k20a has better exhaust manifold than EP3 K20a thats why it makes 5 hp more. Accord Euro R has RBC intake manifold (same as found in 06+ Civic Si) versus EP3's and DC5's PRC intake mani. Euro R's oil pump is also is equipped with balancer shafts which make engine smoother but rob some hp.
Differences between K20A3's.
EP3 K20A3 comes with PRB intake manifold from RSX-S K20A2. Base RSX k20a3 on the other hand has plastic intake manifold. EP3 has oil pump that is equipped with balancer shafts which make engine smoother but rob some hp. DC5 k20a3 has same oil pump as RSX-s K20A2 and it is therefore more suitable for high revs. Although both cars come with 5 speed manual final drives are different in two cars. EP3 has 4.7 fd and DC5 comes with 4.3 fd. This makes EP3 have shorter gear ratio. EP3's intake manifold makes enigne more suitable for mods and gains are bigger, but on paper it makes less low end tq, that is why there is 9 lb-ft difference between two cars.
