Still man what is the point of doing so, When an 240sx pulls up you expect a certain sound and feel. American mussel inst one of thous. What would you say if ya saw a charger with a skyline engine totally different feel and design to me its just wrong. If you feel the need to re invent the wheel go ahead am not going to bash ya its just y bother putting so much time and money when you can get a SR or Ka or even a Rb26 and build it. Just turbo a ka and you will be making 300 ish hp sounds good and suites the car. And your Mazda thing does not apply with this some engineer’s one day say we want this engine in this car and it came factor like that. I haven’t seen any Nissan 240s come out of the factory with Ls1 or small block Chevy’s. And if you want to go fast really fast make a shifter cart takes brains money and balls 250 pound cart with a Honda Cbr 929 engine you will be flying. Not trying to argue it just i like to use Nissan parts on Nissan, Vw with Vw and Chevy With Chevy. Different parts of the world different feeling and different style some witch should not be combined but thats just the way i c things.
