Had a nasty knock on the front of my evo9
my ARC intercooler's pretty warped because of it
mechanic recommended me to replace it with a stock one since they don't make them any more.
my question is,the 4g15 with siemens ECU can be matched with high cam?i think it does need a piggyback to fine tune the fuel.so does this kind of mod possible?need ur expert advice.
