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

Despite the age, the radiator seemed to be fine with very little leakage marking.
No wet marking so should be fine for a while but any thermal shock will accelerate the fatigue so at some point, please replace it at the first sign of blue marking.
The OEM radiator is a consumable parts but probably one of the most neglected service.




However, the damper lower bush is showing the sign of age and almost dead.
Not easy to understand it from this photo but the bolt is not sitting at the centre of the eyelet and instead, it shifted towards the bottom side massively.
Nothing new and almost all NSX are showing this if the damper body was never replaced.





FL sway link really close to the damper body.




As mentioned many times, please do not use same stainless material on both the bolt and the nut in the exhaust area.
100% guaranteed to seize.

If using stainless, at lease please change the composition.

Mentioned this to the certain owner when I installed the same aftermarket header but seemed to kept using the same bolt/nut for ages and the same combination were found on the newly installed exhaust back box…..

I’m glad I’m not going to touch the exhaust area this time.
Once seized, it’s a big job cutting through any stainless material.






The exhaust pipe exits (tail pipe) are bit too close to the skirt at the R side.
Not melting the lower skirt though.....




It’s been a while since last time I saw this tall filter…..




The drain bolt looked to be bit loose and making the pan wet.
I hope it's not the result of cross-threaded plug......




The pretzel style exh back box…. Another 60mm pipe diameter spec from US…..
Interesting to see how it shifted the lower rpm range torque with slower exh flow speed.
