Good buy?
 

I've contacted a guy about a Nissan 300zx z32 right now the car is a na automatic trans and he has the tt engine and Manuel trans he accepted my offer of 2500 is it a good buy ?

Not sure what you mean. Are you buying the auto NA car only? Are you buying the TT engine and trans only? Are you buying a car that was NA/auto but is now a TT/manual conversion? Are you buying an NA/auto car + TT engine + manual transmission?

The car has the auto na and comes with tt Manuel needs to be swapped the guy wanted to do it but never got to it so he's selling me everything for 2500 so I'm getting the car in it auto na and with the car also comes the tt Manuel

I wrote in reply

So does the car currently run?
Are you going to do this swap yourself?

$2500 for the car and TT swap is a good deal in parts, but the swap will probably give you many months of headaches. :D

I agree, if it's all in decent shape that's a steal. It comes down to whether or not you're willing and capable to complete the project.
