that is for the plenum, and the runners will match as well, not to mention the Tb when i have the money for it. so if the stock tpi wall is 5500rpm or 5000rpm. what is the difference now between the super/stealth rams and this mega porting besides this is factory looks.
i just dont want to do all this and then ahve the car fail emissions/run like garbage. so before i spend any money, other then buying the motor. i want to make sure everything will match up and be ok when its all said and done
