NSX chassis

[stevecct]

91-94 all have the exact same chassis regardless of transmission. 95-96 Targas have a reinforced chassis through the B pillars and side sills using thicker aluminum extrusions. Again regardless of trans. 97-05 have the same reinforced chassis as the 95-96 Targas, regardless of trans and regardless of coupe or Targa. They also use lighter body panels compared to the 91-96 cars.

Your tech is wrong. I fully swapped my 92 to MT including the cams and valve springs. Changing the ECU is as simple as cutting a single resistor and boom you have a MT. Unless you change the valvetrain I recommend keeping the AT ECU setting.

Regarding to ECU R04 resistor removal, will it also increase the max rpm to MT engine level!?

Yes

it doesn't matter until you drive the car to its limit on the track.
