i think the S is cheaper to maintain stock s vs stock nsx

imo, if i can't afford to keep the S and teh NSX together, i'd just save some more. i read so many threads of ppl wanting back an S for that raw feeling

 

a test drive will really help you figure it out. you already had a good run with an s so try something different. if you really want another s then im pretty sure it will be easy to sell or trade your nsx for a ballin s2000.

 

NSX, you'll hold onto most of your resale that way.

 

NSX

 

Ckit is correct that the NSX will retain value better than a modified S. But, cost of maintaining & especially repairing the NSX will be many times that of the S. Have you priced NSX parts? New or used, expensive.
I also contend that FI adds very little to resale of an S. In general, modifications to a car are terrible investments. Your only reward is your enjoyment.
I'm 61, owned over 200 cars & bikes. Your best value is a stock or near stock vehicle, purchased 1-3 years old. Since 1992, I've driven two new cars 4 years each plus ~10 late model used cars (MSRP ~ $14k-30k). I have spent less than 5 cents a mile for depreciation + repairs. Modifications limited to wheels/tires, purchased used.
Controlled, careful spending helped me retire in my early 50's. Now I can take my garage queen stock S out any nice weather day... and it it doesn't feel underpowered to me.

 

2002-2005 NSX prices seem to be from 40K to 80K. The NSX looks pretty nice but i really enjoy top down motoring, closest i can get to a motorcycle without getting one (family and GF against it). if you can afford both, great, if not, just stick with the S2000. i personally would not turbo the S2000 to the extent you plan to, increases wear and tear on other parts of the car. then the boost addiction kicks in and you get to the point where it is hard to DD it.

 

NSX

 

BOOST!! its up to you though I the S2k and the NSX but for whatever reason I just wouldnt want to own an NSX but maybe if I had a second car for DD and such I might feel a little different. I worry about my S2000 all the time when its parked anywhere but home, I dont even want to think about how much worse I would worry about an NSX

 

If I had that kind of decision I'd get the NSX and build it

 

If I had "enough money" then I would say NSX. Who wouldn't. If you can say well I am gonna keep my S and turbo it or if you had the pockets to say I'm gonna buy a NSX, get it where I want it to be and turbo that then that is the way to go. If you only had the funds to turbo one or buy the other and save save, credit card, save, then I would say keep the S. Best wishes for whatever you do!
