whats the difference internally between nsx / nsx-r ?
- Thread starter ChongLee
- Start date
weight difference, suspension difference, brakes (pads/rotors), gearing, guaranteed build-quality (blueprinting, balancing, etc.), limited production/resale value... the NA2 nsx-r also has some aero tweaks (wing, front bumper, undertrays, diffuser).
These are generic areas of improvement, there are obviously a number of itemized enhancements that create these advantages, such as a lighter rear spoiler on NA1 nsx-r, lighter seats, lighter wheels, etc.

The power rating is officially the same between the regular NSX and NSX-R; the difference in production is additional time spent verifying the quality of the engines intended for installation in NSX-R cars, by having lower tolerance levels for irregularities a pristine example of the standard engine is created.
There is some debate as to how much performance gain this results in, over the regular NSX. Some people have claimed upwards of a 20hp gain for the NSX-R, while Honda insists, on paper, it is the same rating. Some people also claim, with no official proof, that Honda's press NSX-R has an even higher power rating.
I could have sworn I saw the NSX-R on top gear and they said it had more hp than 290....but it's been a while since i saw it. also, along with all the other stuff you guys said, i think the glass hatch is lighter glass?

It better be more than that if those guys at best motoring are always killing Ferraris, Lambos and Porshes. :biggrin:
- the partition glass weighs less
- no stereo (stereo delete plate)
- different shift knob/boot
- different steering wheel
- different gauges
- different carpet (lighter, brighter :wink: )
- different seats
- dash is suede-ish (so there's no glare)
- stitching
- floor mats
- badges
- different ecu
- carbon vented hood
- carbon trunk lid
- carbon (and different style) spoiler
- carbon mirrors (btw, i've never heard of anybody having or making these... is there not a market for them?)
- engine is built more meticulously
- trans has 4.23 R&P
- shorter gears
- dual disc clutch
- hard top
- coolant bottle has a black cover on it
- engine cover is different (mesh)
- diffuser on the back
- front aluminum under tray
- better brakes
- better suspension/lower ride height (-0.75in)
- different wheels (white, light)
- different tires (RE070)
- different front sway bar
- insides of headlights painted
- 2 tone paint job
- black engine bay
- right hand drive only :wink:
- button for antenna to go half-mast (can somebody please confirm this? i saw it on top gear, but why the hell would you need an antenna if you don't have a stereo??)
i'm sure i forgot a few things
Different/Lighter door panels
The factory NA2 NSX-R uses fake carbon fiber mirrors, they are a 'carbon look' finish.
Procar produces actual replacement carbon mirrors, if you have the resources on hand.
the nsx-r uses fake cf mirrors? how lame is that?
Nope, I believe it's alot lighter so it can rev up alot faster!!:smile:
I also heared it doesn't have power steering either.
John, I don't think that is true. The NSX-R Concept Prototype had the wet CF mirrors, but the production cars are regular mirrors painted black.
With Stereo option, yes, it is true. Top Gear tested a fully equipped NSX-R with AB, AC and Stereo.
In several magazine articles, if was mentioned that although the NSX-R officially only has 280HP, that 'those Honda horses seem to feel friskier than others'.
I believe than after the NSX-R was tested by the German Sport Auto magazine, it was put on a dyno and it came out with 309 HP. Detlef from ProCar has more info on that.
I also remember reading that same Detlef now has a nice original Honda NSX-R engine in his own car which, combined with all the other stuff on his car, manages to bring it up to 338 HP which is quite nice for a NA 3.2 engine I think :smile:
I read that before about the antenna half way. How anal is that?
Not as anal as the shifter boot in the mesh which saves 10 grams. I think Hammond from Top Gear said it best. "I could have done that by wearing a different pair of socks!" :tongue: :biggrin:
Personally, I don't think Honda would change the shift boot just to save another 10 grams but more to change the apperance of the car.
Of course, Honda did a great job in making the NSX-R lighter, but if they had really wanted it, they could have probably saved some extra weight in a much more meaningfull way
- lighter exhaust
- lightweight side-scoops
- lighter windshield (they did that on the 1992 NSX-R, but I never heard they repeated that on the 2002 NSX-R
- no antenna at all
- lighter bumper beams
That's a nice list Synthesis. I remember reading a thread awhile back that was posted by a guy who actually had pictures of an NSX-R (maybe he owned it) and had a really cool list of differences. Here are a few more that I can remember...
- spare tire deleted (replaced with radiator duct.)
- air pump deleted (replaced with a can for tire inflator.)
(I can't remember for sure, but maybe the whole tool kit was deleted.)
- some interior vinyl coverings replaced with a rubberized material
- There was a button on the dash that was deleted (I forget which one.)
There's more, I just can't remember. I tried finding the thread without success.
It's no secret the NSX-R's engine is balanced and blueprined to give it up to 10% more hp than a OEM C32. Honda's official 290hp claim is only to abide by the nonsensical Japanese "gentleman's agreement" not to exceed 300hp (which I could never understand as both the VR-4 and Supra had well over 300 hp since 1993 )
The only debate has been whether the 2003+ OEM C32 engines were also B & B without Honda acknowledging it. There's been quite a bit of anecdotal evidence to suggest that it is the case. When you only build 400-500 cars per year you have plenty of time to B & B every motor.
But why?
