ok i know this might be a stupid quest due to the fact that the compression is raised i think somewhere around 11:1, i have a B18c1 with type R pistons can i safely boost with a good tune and if so how much should i boost the motor has about 60k since rebuild and blew 180 across the board when i compression tested it the other day

 

O YES an i forgot!!!! im trying to make just around 250-300hp

 

Instead of accepting your typo's try fixing them. Yes you can boost safely with high compression with a precise tune and proper fuel.
