ok this might seem like a dumb a** question but my friend was pretty up on nissan for being a toyota guy he said that a vq should swap straight in no real problem that it should use the ka mounts and the drive shaft should fit from 300 to 240 ive searched around the best i could to find any info i could and theres been conflicting reports from other sources some say yea it will and some say no it wont any help would be great i found a 300 at the junk yard motor will cost 200 with trans and harness another 50 and also a bit off topic sort of but ive been told that the vq's had problems with oil leaks yet again any help would be great

OP... bish slap your friend. This swap is very involving. But don't let that scare you away. There are plenty of resources on NICO to help you.

FWD VQ engineRWD intake manifoldRWD exhaustRWD upper and lower oil panEngine/dash wiring harness from the VQ car you got the ecu and bcm fromNVIS or NATS with key from the fermentationed car My mounts which use the 300zx motor mounts and trans bushinga drive shaftRWD vq35de transmission revup or non revup doesnt matter just needs to be the same generation of VQ since HR,DE,and VR trans are not interchangeable. RWD waterpipesGreffin RadiatorMy shift linkage kit or the guy from vq240z.com's kit he is selling on hybridz.org. A custom exhaustAn ABS source IE an ABS diff or abs spindle to get a Speed signalDakota Digital Converter to convert ABS pulse into speed pulse. To 'smog' the car or ref it and get it BAR approved you will need the catalytic converters from a RWD plat formSmog equipment from the car you took the ecu/bcm/nats/key fromyou may need an IPDM depending on the ecu you use. You will need to upgrade the fuel pump to a 300zx or Q45 or a walboro 255lhrYou will need an aftermarket FPR preferebly a nismo or aeromotiveyou can use a FPR off of a VQ30 but you will need to modify to fitYou need a DBW gas pedal obviously if you use a DBW VQ ECUthe one from the z33 and the 5.5 gen and 6th gen maxima work
And this is the cheap route...

Awesome. You need to troll the VQ engine sub-forum. And maybe get in touch with IRAX, because he's making swap kits with the possibilty of sending them into mass production. That might be helpful to ya. GL.

First thing, You keep saying VQ but if its from a 300 it would be a VG. They are totally different motors that have totally different specs.

Second they are not bolt in swaps, but they are doable.
