Is it possible to boost a b18b1 stock engine? what mods should be done without tearing into the block or head? how much boost can I push? I am not looking for extreme hp gains. I do expect, however, about 30-50 hp. Do i need to upgrade the injectors and fuel rail? if so, to what floww rate or CC? I just need the specifics for about 7-10 lbs of boost. nothing more than that is neccessary. Will i need to upgrade the ignition? if so, what is recommended? also, what FMU is recommended? and help would be appreciated, thanks in advance.
