As far as I know retro fitting it is possible. There are parts that will need to be changed such as the fuel sock and rewiring.........As far as I know you would need an FPR when using the TT fuel pump.....eastreetmotorsports wrote:been doing some reserach on this, is a 300zx TT fuel pump a straight plug in to the ka plug or is there rewiring needed to be done and is there a gain on PSI vs the KA stock fuel pump???? i know it can be used on the SR so i was curious, forgive me if this topic was discussed before but when i did a search i couldn't find a simular topic.
