2003 350z Track edition De engine swap with 2017 370z nismo engine Hr.
 

So I put in the 2017 370z Nismo engine, manual transmission, front Chasity wiring harness, engine wiring harness, and 2016 370z nismo ecu/bcm installed and ready to go. What else do I have to do get engine ready to start? Is there a way to Re-flash/reprogram the CPU myself(if not where can I get it reprogram and how much)? What equipment do I need to do it? What problems am I gonna run into? Do I even need to reprogram the cpu? I dont care to much about Christmas tree dash bored. Just want get this car running and driving. I also got the key from that cpu, but didnt see a reason why I need it? P.S. Havent attempt to start it yet. If you have any question please ask away. Ecu and Engine isnt from same vehicle also.

wow...

I would think that researching and gathering answers to these vital questions would've been your first objective prior to carrying out this engine swap.

If you have the ecu/wire harness it should fire right up no problem.

I have done a lot research but kept getting different answers, and this swap hasn't been done much at all, also a lot people gave the wrong info. Just trying get an answer what so might have missed.

give 'em hell...in for the turn of the key!

Any update on this swap? I've currently got a vq37vhr sitting in my garage, and an 04'Z not running right.
