Hey i gotta 03 G35 that i purchased with auto and i really regret it, but i dont wanna sell my baby, i was thinking of doing swap for a manual. I know I need to buy a new tranny but what other parts do i have to purhcase, and can anyone please generalize the steps. Trying to find DIY for this car but cant find it.

 

There's no DIY. Search does help - https://g35driver.com/forums/g35-sed...onversion.html

you're betting off selling the G and buying a 6mt

 

Apparently both the op and second poster failed to search, there is a DIY:

Also, to your question is it worth to turbo instead. Turbo will be considerably more than a 6mt swap. You should look at a transgo + paddle shifter install instead for a more realistic comparison.
