U will loose low end power but better gain for high end power...fuel consumption wont effect much...
Any reason u want to modify your dual runner intake manifold?
i have installed in 87mm piston to my vr4 block. currently its abt 6mm sitting low from the head. is there a way to compensate the loss and still able to run it normal using standard wiring, ecu? plans to get EMS end of the year.
