if you guys were going to turbo the 3.5 what would be the biggest problem? friend of mine has he altima and is trying to go turbo. do you guys know anything about the returnless fuel system? how does that effect turbocharging? will two extra injectors slove this problem?

 

i don't know if there is room for it

 

relocate the battery to the trunk?

 

battery to the trunk and obviously you will have to get rid of stock intake, then you will end up with 1/4 empty engine compartment.
