That is correct. Ludes, and pretty much all other Hondas have an open deck motor. It has tunnels with coolant running through the block. If you run more than8 PSI for any amount of time it WILL crack your block. If it was meant to be turbod it would have a solid deck cast Iron, not aluminum, block like a DSM 4g63. Plus you should show a little honda pride, they thrive on making vast amounts of all motor small liter horse power. And another thing Ludes have 10:1 compression, which is rather high to be boosting so Youd need new pistons also on top of having to have it sleeved to prevent a big hole in you block.
