I put a JDM SR20det into my 91 G20. Its just a regular SR20 but i got the jdm one becuase i worked at an importer. I put the engine and tranny in and now the car will only start with the gear selector between park and reverse. I have tried adjusting and a new neutral saftey switch and we can get it to work correctly. Also i tried to replace the axels and only one was the right length. This is leading me to belive that i cannot use the JDM tranny in the car. My stock one was shifting hard so i put the jdm one in and scraped the stock one. Also i think the car is from Canada becuase the speedo in is KPH and there is french writing on the gas door. Also you have to press the second button on the bottom of the shifter to get it out of gear. If anyone can help me out let me know.
