I have an 06 g35 6spd and I was just wondering if I could buy an automatic engine and the transmission threads be the same? Because I've looked for motors and all I can really find is automatic motors. I'm keeping my old transmission and just needing to swap the engine because it is blown. So if anyone can help and say it's okay if it's an automatic engine that would be great! Thank you

 

Actually just needing to know if bell housing will line up the same Is what I meant

 

Yes but the auto have a pilot bushing, you'll need to remove this bushing and install the pilot bearing, might need a tool... and just make sure its the same year.. de to de, revup to revup
