Another NSX with partially dead side Eng mount.
Not much I can do without replacing it.
The problem is the cut near the centre around the centre bolt and not the cut close to the outer edge.
It's designed like that for NVH purpose.

Something to be done at the time of next TB/WP service as this NSX is still using the original WP.








Partially cracked door handle at the left door…

I hope I don’t finish it while removing the door card for the speaker AMP service.
I wonder whether Bose USA will ship just the AMP to UK or not….












Yes, it’s leaking the coolant.
Another cracked header tank but won’t be surprised as it looked to be the original one.
All these greenish debris are of the coolant.....








The owner already took some photos for me and confirmed that the radiator was already leaking
so we are going to replace it at the same time together with all the coolant hoses, thermostat, coolant tank, etc.












Nice to see another NSX with KSP header.
Super expensive but dyno proven performance and makes distinctive sound at the idle rpm.

And the expensive Fujitsubo Ti exh back box.

To my ears, I prefer the sound of stainless back box but still, fairly quiet (probably too quiet for some) at idle rpm and
very nice roar once opened.

I was very interested in this combination especially on AT model because of the torque curve shift.
Lots of aftermarket exhaust area parts especially the ones from US are using large diameter pipes
resulting in shift of torque curve towards the higher rpm band.

Also, some of the headers design are not ideal when it comes to the torque changes.

While it may not be a problem with MT model, it could result in sluggish feeling at very slow speed range
like when you drive through the residential area or slowness on launch at the stop light specifically for the AT models.

With these combination of header and exhaust on non-DBW, non-LEV model AT NSX, I didn't feel any negative feeling
so they are working really well even on the AT models.

Just shows the importance of good quality header/exh combination especially on AT models and very good investment as well.
