Whats up everyone. New to this board but did a ton of searching before actually posting. I just finished a 96 B18C (5) JDM swap in my 92 EG VX. It runs great, except every once in a awhile the speedometer starts to flick all over the place and when I hit about 6k rpm it falls flat on its face. Is this a wiring issue or possibly a lack of fuel? Or could this be related to the Speed Sensor? Since the car was a VX it was prewired for Vtec so I didnt have to do any wiring. I bought the motor from Hmotorsonline and they sold me a jumper harness to make the ECU plug and Play in my car. Tried to give as much info as possible. Any help would be great. Thank you guys.
