So i have a 91 twin turbo and i have decided to look for a new engine. I would just sell the car and buy a used 300zx twin turbo, but i feel like i spent a lot of time and money already into this car and dont want to let all of it go to waste and thats why i am not selling the car. the engine i have in it now is a little old and has 153k miles on it. I wanted to know if anyone knew where i could get a used vg30dett motor with low miles on it so i can replace my old engine. i want to start from a lower milage motor so if i decide to modify it, it wont be as old and maybe last me longer (daily driver). Please let me know of any websites that you know of that has good motors for a fair price. Thanks
