Hey preludeonliners, I was just wondering would it be safe at all to boost a stock jdm H22a? Would doing internals be absolutely necessary to boost period? I'm not really even trying to do high boost, low boost would be fine. I've heard that 8-10 psi would be safe for a stock engine, but at the same I've read stories where without any internals sleeves would start flaking up and pistons eventually breaking. I wouldn't mind settling with maybe 4-6 psi if it would mean no engine damage, and if I swapped out my ecu for a Hondata S300 with a proper tune would that help insure a chance of anti damage to engine with low boost? I've read the sticky about building a turbo engine but money is tight. Any comments and/or critcism would be great. Thanks in advance .
