I want to buy a 99 maxima with 70K miles on it, it comes with a supercharger!
and comes with nos and the guy built the engine it has better pistions and better clutch and trans and axcle basically the engine is fully built My question it do u think i should buy it because i think the engine might be messed up due to NOS but he olny said the nos as been there since the car had 60K on it what kind of damage should i look for if there is any?... the car runs great though and it is tuned great as well.. how much damage do u think the NOS is doing to the engine????????? need answers asap want to buy car soon ! thanks guys

 

What pistons did he use and what compression ratio? What did he do to fully build the engine?

Do a compression check. If the compression is fairly even and not too low, then the engine should be in good shape. VQs can take a lot of abuse.

Oh, and try to use periods every now and then. It makes your messages easier to read.

 

Unless you know how to work on Maxima's, SC, or nitrous systems or are willing to learn I would really think twice about buying a car like that. There will always be little issue that come up and if you did not install of all these aftermarket parts your self or have done something like it before you could spend alot of money on labor in the future. Just something to think about.

Also if I were you I would want to know exactly what was done to the motor and get documentation. It is real easy to lie about that stuff. Not that who ever is selling this car is trying to cheat you, I dont' know that, but you need to make sure you know what your getting into.
