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

Although the OEM sensor was from Denso, I prefer using the NTK/NGK O2 sensor.

I'm biased because of the actual experience developing the certain components with them for the racing project ECU and I know how good they are.

Due to the design of the aftermarket header and some of the parts around the cyl head not installed properly,
very limited option for routing the cable but happy with this position.

You really don't want melting the O2 sensor related connector/wire as it could damage the circuit inside the ECU and would result in expensive repair/replacement cost.









Another NSX with huge dent at the oil pan/sump.

The owner is aware of this.











Preparation for the compression check.
