Today at Atelier Kaz - ex-Honda R&D, F1, Indy/CART engineer

The left side intake duct.
It’s early model AT so bit different from the MT ones.

The know-how of torque and power curve.....






As far as I know, this NSX went through some big services and the owner only uses NSX on very rare occasion….
Yet, the air cleaner element was so dirty. The reason is beyond my knowledge…..








As the owner doesn’t use this NSX much that he was not aware of this but the Main Relay was the original one from the factory.
Already many soldering cracks inside there so replaced with a new one.

Not sure from when but as reported long time ago, if you place an order for the Main Relay, you will receive the one with improved soldering.
The manufacture changed the amount of solder used and it has much better tolerance against vibration causing the soldering crack.




Compression check time.
Despite the poor previous service, the deviation between all six cyl was not the best but well within the window.
I have seen much worse data in the past.
At least, something was fine....
Will check the cam timing once I have removed the valve covers.






It was not included in the service menu but after smelling the eng oil, decided to check the state of the IAT sensor.
It was covered in full of black gunk so cleaned it and installed with new o-ring.
