So, IDK about you guys, but I've been needing some inspiration for completing my VQ swap when I'm surrounded by turbocharged engines all day. So here it is, lead car is a stock VQ35DE

Well guys i have finally have my car consistently starting and running. I put in a call to the boys at Z1motorsports. Great bunch of guys there, very knowledgeable. They knew what my problem was and were quick to help. Cant thank them guys enough, especially John.
For you guys who are going through this swap and/or will be in the future i suggest you give those guys a call for any services you need. I Hope to be posting pictures of my 97 240sx running and driving in the following months. |

It was a ecu tuning that needed to be done. Unfortunately the general public doesn't have access to certain functions such as the removal of the Nissan anti theft system (NATS). This is where a pro tuner is needed. John at Z1 knew exactly what to do and the turn around time was great.

so im getting a vq from someone and they have engine only (no tranny, no ecu, no pedal).
i'm planning to rebuild to factory specs so my question is, can i use an ecu from a different vq engine to work with the one i'm purchasing(03, 04)? |

there are many issues with swapping ecus.
my friend had an issue unlocking the ecu he was trying to swap in. it isnt cheap if i remember correctly also pretty positive you cannot use the vq35hr ecu with the de engine. They are very different engines. single intake vs twins. an extra 1000 rpms in the tuning. etc etc pretty much a completely different engine. |

well apparently this engine (vq35de) is either from 03 or 04 model.
and this guy says i can take an ecu from another vq thats either 03 or 04 and it'll work.. thoughts? |

Here is some VALUABLE info (non-HR):
ECU's Automatic: 03-04 "DE" [4 pin o2][AVOID 03 G35 sedan ECU *COUPE ECU ARE OK*] 04.5-05 "DE" [5 pin o2] 2006+ "Revup" [5 pin o2] Manual: 03-04 "DE" [4 pin o2] 04.5 "DE" [5 pin o2] 2005+ "Revup" [5 pin o2] Harness' Automatic: 03-04 "DE" [4 pin o2][AVOID 03 G35 sedan harness *COUPE ECU ARE OK*] 04.5-05 "DE" [5 pin o2] 2006+ "Revup" [5 pin o2] Manual: 03-04 "DE" [4 pin o2] 04.5 "DE" [5 pin o2] 2005+ "Revup" [5 pin o2] With this being said you can use Any combo of ECU's and Harness as long as o2 sensors match and they belong to the same group "DE" or "Revup". Examples: "DE" ECU Harness/O2 on "DE" Block "DE" ECU/Harness/O2 on "Revup" Block *4 sensors will remain unplugged, but will work fine* "Revup" ECU/Harness/O2 will only work on "DE" block if the DTC's are disabled *03 g35 sedan ECU/Harness are that of a Maxima* Wiring in to S13/S14 chassis Most wiring guides out there are misleading. There are many easy ways to get this done. If you need help or have questions, shoot me an email at [email protected] ECU Codes Most of these will not be needed as the VQ OE components are not needed. A brief list of what can be disabled on the ECU and allow the motor to operate normally: Secondary o2 Sensors Fuel Tank Temp Sensors EVAP controls Speed Sensor Power Steering Pressure Traction Control Fuel Level Catalytic Converter Check AND MUCH MUCH MORE!!! If you need info on ANYTHING regarding this swap in to s13/s14 shoot me an email at [email protected]

Let me set this straight
Ecu wise you can concider 4 different types. A-03/early 04s use narrowband o2 sensors B-Late 04s and 05s use widebands C-all 06 and the track 05s are rev ups and use an ecu that controls it D- 07-08 are all HR motors and uses that ecu Each of the 4 types of ecu has a harness that must match (modification can allow changing them) Ok. But there is only 3 motors 1- vq35de non-revup (can use a or b but the harness needs to match the ecu) 2- vq35de revup (uses c) 3- vq35hr (uses D) So I can use an 03 motor with my 05 ecu and harness. Or even visa versa. To keep things carb legal you would have to incorporate the evap system which gets pretty elaborate with the fuel tank and canister setup but is very doable.

Hey guys, I'm in need of help, I need to figure out where the 6 wires on the throttle body need to end up at the ecu,what pin numbers? I've been through it but I've got to be missing something. Having issues with only a couple codes, mainly the low voltage correlation.
I've gone through the Accel Pedal wiring and the 6 wires end up at the correct pins in the ecu, but I'm unsure of the throttle body itself. I really need to figure out what pins they're supposed to end up at and what position on the TB plug, like how it's shown in the thread for the Accel pedal. Also, I've found this on the interwebs, but there's no clear pin numbers http://www.linkecu.com/support/docum...e%20Wiring.pdf I really appreciate any help you guys can throw at this, I'm stuck and only waiting on this to get it running! Here's a pic for inspiration!

So i haven't really had a lot of time to work on my car. The last thing i did was some wiring when i was able to get it to run. well as of this past weekend i cant seem to get my car to start. Throttle body doesn't function at all, as well as no spark of fuel from the injectors. No new codes on the ecu. This whole thing is killing me... I cant seem to get ahead.
The only thing that i did differently was install a new battery. Also my ecu was unplugged since i last worked on it. |

Has anyone had any power steering issues on their vq swaps?
My steering was stiff and shaky when turning fast which could mean power steering pump. Yesterday the steering rack blew a seal leaking everywhere. Is it time to rebuild both? P.s. Im using the Chase Bays setup |

My goal is to setup the VQ in my s13 and make it street legal. Anything else is secondary as this will be my daily driver...and i don't trust my luck with . What options are there for hood clearance? Also, what options are there for exhaust headers? I hear stock hits steering rack so thats a no-go? Thanks for the ECU info, i'll keep that in mind! I now have a VQ from 03-04 350z (engine only) sitting in my garage~ |

http://zilvia.net/f/chat/384013-plusoneten-build.html For hood clearance I just used spacers. I could get less of a gap if I cut out some of the bracing. Zenki seems easier to fit too. Sent from my iPhone using Tapatalk - now Free |

HR and DE headers hit the rack. What we do is cut the flange off and a good mount back off the oem header and weld a new exhaust downpipe and flange to clear everything.
