The VQ35DE is a strikingly divisive engine when it comes to winning the hearts of aftermarket enthusiasts. For some it’s a disappointing platform to replace the very powerful turbocharged VG series of motor that powered Nissan through the 90s Supercar battles.
But for many others, it’s an awesome blend of technology and efficiency from it’s forged steel rods, one-piece forged crankshaft, to Nissan’s nylon intake manifold technology, it’s a clear cut leader in the V6 category
The block shares many similar traits as the VQ30DE but couples variable valve timing to take full advantage of it’s displacement to generate 228-300 hp / 246-278 ft. lbs at the flywheel. Although it took some time for the aftermarket support to come around, the VQ is now undoubtedly Nissan’s signature powerplant as it’s now developed into the what is now found in the new Skyline GT-R.
Although swapping a VQ35 isn’t as popular as some of the other forced induction options, it’s gaining in popularity due to the many vehicles the motor can be found in as well as the variants that can be found in many different displacements.
One of the many questions we get here at Pro Street are regarding engine swaps, and the electrical wiring of the PCM into the chassis of your choice. Most of these swaps revolve around the 240sx, a common candidate for engine swaps, although we will be looking at how to wire in the VQ35 ECU into almost any vehicle of your choosing.
Although this How to Wire your VQ35 Swap writeup is typically for the 2003–2006 Nissan 350Z and 2003–2007 Infiniti G35 versions of the VQ, you can just as easily select one of the FWD versions of this motor.
Usage of different mounts may be required when swapping them into your car. Such FWD versions can be found in the 2002+ Nissan Altima, Maximas and much more.

Can you send me more, detailed info about these wires and where they go? Thanks!
Hi Anthony! Thanks for commenting!
What wires are you in need of help with? Let us know and we can help you out!
Does this wiring config work to swap into a 240sx
Hi Nick, yes it does. Check out the 240SX wiring guides here to figure out how to wire up any swap into a S14 or S13.

I’ll be swapping a VQ into an 86 Fiero. Is this feasible and if so will this diagram help me on the way?
Hey Geoff,
Sounds like an interesting project! You can start by sourcing a proper VQ ECU, and powering the main relay and ECU to start with. Once you get this done, you will need to figure out how to get the sensors working from your Fiero. Im assuming you will be using a manual transmission, can you share any more information on your VQ swap?
What differences are there in pinout from usdm to jdm. Did a swap and fuel pump not getting power
Hi Bernard, you swapped your VQ35 engine for another engine? or you swapped the VQ into something? Have you tried to rewire the fuel pump itself?
hi.
i would like to wire a vq35de into a 90 mazda b2200.
can you share that knowledge please
i dont understand 5v on pin 90 and 91 and how to disable vats and what sensors are required.
your guidance is required.
Hey Naraad, that’s definitely a VQ35 swap that’s growing in popularity lately. I’m more than glad to help where I can. Switched 5v power can easily come from your Mazda ignition switch. This is the pin with power with the ignition key set to the “ON” position. To disable VATS, you are best going with an aftermarket bypass as most of them come with the right hardware to complete this VQ swap.
Let me know how the project turns out! Thanks for reading!
Looking to swap a vq35de with 5 speed auto into my Mazda B2200 pickup. I know I will need the drive by wire accelerator pedal and the gear selector/shift mechanism to make it work. Is there anything else that I am missing besides: custom driveshaft, fuel pump, custom motor mounts, transmission mount and exhaust system? Thanks
Anthony, you will also need a VQ engine harness and ECU. I would recommend keeping your Mazda harness in place, and wiring in the MFI relay from the VQ to simplify your swap. Sounds like an incredible project, keep me updated! Best of luck to you
