the QR’s factory fan relay. From there, you can put 12 volts switched
to the factory relay, and just run the fans constantly. This will help
keep things cool under the hood.
The wiring is a pain in the butt.. no way around it. You will end up
using sections of your QR harness along with the donor VQ harness.
Take your time, and if you need diagrams, let me know. I will do my
best to help you.
You MUST use the NATS (Nissan Anti Theft System) with the VQ
ECU. There is no way around this. If your car has the system
already, then it’s a simple task. You will need to wire up the Consult
plug to the VQ ECU (just a few wires), and have a Nissan Technician
re-flash your ECU/IMMU to allow the car to start. The only way
around this.. is if you were to get the ECU, IMMU unit (black box
around the key cylinder) and matching key, ALL from the same donor
car. If you get those parts, then, you can hook it up, and it will start
right up from the get-go. If your car came without NATS.. you will
need to source all of the components, and wire it up manually. Again,
wiring diagrams can be had for free… just let me know.
As for exhaust, you will need to have a Y-pipe made to come off of
the stock manifolds. I HIGHLY recommend purchasing aftermarket
headers/y-pipe from a VQ30 Maxima. This will bolt on, and the Y-
pipe can be modified to work in the Sentra without much fuss. I
recommend a 2.5”, mandrel bent exhaust system as well.
The VQ35 responds well to exhaust/headers, intake and a good tune
(AFC of Emanage). On slicks, expect mid-high 12 second ¼ mile
passes with full interior. With a gutted interior and bolt-on’s, expect
low-12 second ¼ mile times.
If you are going to install nitrous oxide, it’s a good idea to go with a
larger fuel pump. The Maxima pump should fit in without any
modification.
It’s a good idea to replace the belts/spark plugs with new units before
installing the engine..
