I was wondering if an upgraded fuel pump and fpr necessary when u up the compression to 11.5:1 in an ITR motor ? and the other mod is just an exhaust. What other things do you guys suggest to do to make more power (Talking to the 13 sec All Motor ITR's out there.... thanks

 

Is the ITR fuel pump an upgrade over the GSR's? Or is it the same pump?

Also is the fuel rail the same as in the GSR's?

thx

AL

 

Or just a fpr good enough ?thanks
