K24A1 CR-V bottom end with a K20A3 RSX Type S head. The problem is that the K24A1 has a massive stroke- 99mm. In order to get that engine spinning at 7000 RPM, you'd already be at some crazy piston speeds- much less the 7900 RPM of the Type S redline.

I have yet to see what the rod length on a K24A1 is, but I'm willing to bet it's less than 155mm, in my book making it a bad rod ratio.

Bad rod ratio + high piston speeds = blown engine. The bolting up wouldn't be that difficult, but making it work reliably would be. I'm sure someone will try it. We'll hust have to wait and see what happens.

i read on another msg board, someone already did this swap.
