Still searching for the perfect ride. Found a nice clean one not too far from me with 100k miles and a CTSC and NOS. Seller is asking 29k. What do yall think? What kind of effect can NOS have on these cars. To be honest, it kind of scares me. Im comfortable with the CTSC as it seems its the most reliable and common upgrade for these monsters. But NOS? i thought that just destroyed motors. Any insight would be greatly appreciated!
 
Personally, I would not buy a supercharged or NOS-equipped car. You don't know how the work was done and what internal effect it might have .. JMHO.
 
It sounds like it might be a very good deal. A PPI would be helpful.
Some of the other Prime members will have more experience in this realm than I have.
 
Man, I hope that NOS has never been used.
 
Nitrous can be safe. That price seems very good!
 
What makes buying a car and getting it done yourself any different? It's not like I have the know how to install it

I think it would be a lot different as you could supervise the install and find the best technician and not do NOS to a NSX to begin with :). Highly modified cars can be headaches if purchased down the line. Just giving you my opinion, you are of course free to follow your heart. :)
 
Like I said, the whole NOS thing makes me wary. But the vehicle is at a large, prominent dealership, don't we hold them a little more accountable?
What are some of the negative effects an improper CTSC install and nos can have?

Depends on the dealership. Many have bad histories of selling messed up cars and not as such.

NOS will cause you to require an engine rebuild probably every time you use it.

I hope you are kidding. Nitrous ran correctly can be just as safe as any kind of forced induction. It all depends if it is a wet or dry shot, how big of a shot, direct/indirect port and what supporting mods are in place (colder plugs, tune, etc).
 
Since you're scared of NOS, then stay away. I think you'll sleep better at night not worrying about your car.

If something goes wrong, then be prepare to shed out more $$$ to find someone who can fix it. I'm not a mechanic so I rather stay away from those engine modification. Once in awhile, I have nightmare about the car not starting up :)

Even if it's sold from a dealership, they probably sell it "as-is" without any warranty.

just my opinion.

I plan to get a compression and leak down test done. What would that cost you think? Can any mechanic do those or does it need to be a honda/acura, or even nsx specialist? The reason I ask is because I'm not sure those will be available in such a rural area. Hoping a regular mechanic can run those tests.

Also, If I purchase the car, the very first thing I am doing is having the NOS system and components removed (I dont even want the temptation of using it to arise) then selling it to the highest bidder, if even sellable.
 
SOS just posted a 3.2L with 48K on it for $6500 today. Just buy it for insurance ditch the NOS. Then you get a CTSC NSX for ~$35K and an extra engine to boot. :biggrin:
 
Wait what? I'm new. Can you rephrase? What's SOS? An nsx for 6500? Or just the engine?

Science of speed is a vendor that is very close to the NSX community. Yep, just the engine.
 
Nitrous done right is safe. Like Batman said, have a leak down test done. If the numbers are right then your engine is safe. Don't worry about pulling out the nitrous, just don't use it. I have 150 shot of nitrous in my NSX and it's fine. I drive around 98% of the time without it hooked up, on rare occasion that I want to use it, I screw on the hose and it's ready and willing. BTW, with the nitrous, its VERY fast and very addicting.
 
I'll sound like an old fuddy duddy here. :)

Does this car have maintenance records?
It sounds great to have a supercharged NOS machine driving around, burning tires, impressing friends and family, young women etc etc.
However if the previous owner thrashed the car or neglected maintenance you will have spent $29K and may need to spend a lot more to fix the car up.

If you are new to NSX, young, not mechanically inclined it would be best to let this one go.

In the long run you may be better off to buy an NSX with good maintenance records, not too many owners, and obviously looked after.
There will always be some spending when buying a 20+ year old car no matter how well maintained. If you have any major work needing done and need a dealer to do it you can spend $2 - 3K easily just on basic things.
Once you have a year under your belt, learned how to drive a mid-engined car, then you can make modifications galore knowing the base car is sound.

Otherwise we will have another thread on Prime about what lousy car an NSX is etc.
