So my old car was a 2003.5 g35 rwd AT I had a trango kit installed and I loved it. Unfortunately that car was totaled out when a car pulled out (not my fault ). Before I got rid of the car I pulled the valve body out and saved it. I now own a 2005 g35x with rev matching (old 2003 did not have rev matching) could I install the whole valve body from my older 2003 to my 2005 without issues. Or would I have to buy a new kit and have it installed. I looked it up and when you buy valve body's it covers both years but one has rev matching. If I swap valve body will I lose rev matching or is that controlled by the ecu. Also are the plugs the same.

2005 g35 4dr berk hfc, stillen true dual exhaus, plenum spacer, 75mm thottle body, k&n drop in, z1 ztube, uprev tune.

 

Probably a different throttle body, there are a few different ones that were used in the RE5 transmission. You CAN however just take the Transgo springs, valves from your old throttle body and drill/install everything in the new/current one. The kit is the same for all those RE5 transmissions regardless of year but the actual valve body itself has other differences so you can't just take the entire VB from the older transmissions and put it in the newer ones. Different ohm solenoids, different wiring harness, etc.

 

Thanks for the response I'll ask the guys how much it would cost to just swap springs out at my local shop that did original install.
