the only difference is you need a lift to get a k-series out of a car from the bottom so you can't repair engines at home like the good-ole b-series that comes out the top.

RSX engine has 11:1 cr, so if they claim 10.5:1, yes they did.

Oh, my mistake, I thought the RSX K20A2 was 10:5:1. I just find it a little sketchy they made that much power on that block with that CR. I always thought Honda blocks needed to be sleeved. Is there any proof it was done on stock block or just some people saying its stock and untouched.

Very impressive! I seriously doubt it would hold together on the street at that power level. This is seems to be "numbers only" tune and I doubt they would ever run around on the street or track with that power level.

k20a2 might be the next strongest stock motor besides the 4g63.

i don't know, stock 2JZ supra engines are pretty stout along with the RB26, both easily handle 800+ wheel HP stock pretty reliably.
