Its normal to re-register a new engine number when you've blown the old engine.
Should I post up pics of my cars and my bros FN2? Theres a reason why the interior badge on the DC2R, FN2, NSX matches the number on the chassis, blue plate and engine. Too bad, EK9 doesn't have any interior badge.
Even my EK9 magazines show all 3 pics of the Blue plate, Firewall and engine with matching digits.
C'mon guys, you saying honda did it on purpose and put the wrong engine into the wrong chassis? And why? When they can get it right.
