DIY: G35 Engine Removal
Here's how to remove the engine from a RWD car.
The first thing is to start by removing the front clip, including the bumper, headlights:
Then I removed the fenders, rebar, radiator support:
Remove the air intake, then disconnect the fuel line and EVAP lines:
Inside the passenger side dash, disconnect the ECU from the main wiring harness:
Then remove the battery and fish the engine wiring harness through the firewall back to the engine. This way its only 4 plugs to disconnect, rather than each individual component on the engine:
Remove all ground wires
Remove power steering lines from the reservoir and pump:
So far most of the top end work is done:
Time to get underneath and disconnect the transmission mount and exhaust headers:
Removing the rear part of the exhaust hanging here:
Unbolt the driveshaft:
Unbolt transmission cross brace:
I dropped the engine down instead of using a crane. These are the bolts to disconnect, 4 subframe bolts and 2 engine mount bolts:
Here's a look at the engine mount bolt from underneath - this will help separate the engine subframe from the block when the engine assembly is removed:
I disconnected the front control arm and its related components to free it from the front subframe:
Also had to disconnect the steering linkage:
I dropped the engine, transmission, subframe with steering rack all down as one unit onto my floor jack:
The engine and transmission finally pulled out - what a mission and mess! I hurt by back on this step.
Removing the flex plate bolts:
Removing the bell housing bolts:
Separate the engine from the transmission:
The engine crane failed us, so we had to tip over the engine to get it upright on its stand.
And this is what's left of the body:
The VQ35DE 3.5L Nissan/Infiniti engine:
All done.

I think a LOT of your photo's failed to upload or something, unless it was supposed to be just a single video.
Interesting way of setting the motor on the stand lol, I appreciate the video for sure because it does cover a lot of useful information for folks about what bolts need to be taken off and such but I just really want to stress to people that if you are pulling the motor with the intention of replacing it with another one this is definitely NOT the way you would want to do it.
This vehicle is going to salvage when it's all said and done so it's perfectly fine to hack the motor out though.
The seatbelt rigging was the best part!

I've updated the image links.
Yes this engine was for salvage, if you cared to remove it to rebuild, then a crane was recommended. The crane I borrowed didn't work so I had to improvise.
