I am restoring/building an old popeyes race cat. Ive got kaama surface drives and twin 454 mercs. I wanna do something one off just have some technical questions that are above my mechanic abilities. Im looking at twin turbocharging both motors. The engine bay is wide open so space is not an issue. I have plenty of ventilation so im not that concerned with heat. The issue ive been googling and cant seem to get a good answer is how to get passed the water/exhaust coming out of the block and into the manifolds and risers than out of the exhaust. Water in a turbo is all bad. Ive been reading about dry exhaust but still doesnt get me passed the water coming out of the block. Any help? I plan on doing this all myself. Not looking for 50k set up. Im not rich. Lol thanks in advance!
