A V36 350GT might be the same as the V36 370GT (not sure if the Sedan and coupe are the same part though). V35 350GT is less likely. Have a search through the link Vee posted and compare part numbers

They are the same as the Q50 Hybrid drivetrain. The HV battery pack is built from 12 separate modules, they can be replaced individually. They are around $1.5k each, or if you want to buy the entire pack of 12 cells, you are looking at more like $12k. I have seen 2nd hand HV battery packs on ebay for around $1.5-2k, but they are usually US based, so add another $500-1k for shipping. I know many people mention it as a concern when considering one, but stories of actual failure are still fairly rare, I guess as they age, we will start to hear of more.

Umm.. speed limits.. yes, all JDM cars are capped at 180KM/H. Power restrictions? nope.. there was a 'gentleman's agreement' between different manufacturers back in in the 90s, which is why you see several Japanese performance cars specify 206KW, with plenty of rumours flying about how much the figures on some were understated (Just look at the official R32-34 GTR specs, conveniently all 206KW) However, that was all gone by the time the V series skylines came along. A VQ37VHR with a claimed power figure of 245KW, is going to be fairly spot on and you aren't going to get a whole lot more without spending some $$ on more than just a few ECU tweaks.

Yep, about the best you could expect from an ECU tune with no supporting mods would be about 10-15KW. Anything that plugs into the OBD2 port and claims power/economy gains will be a scam ,just don't go there! At the flywheel, it is quite a bit less at the wheels where a dyno measures power. From what I have read a stock 370Z is around 200kw at the wheels, so the 370GT would be similar.

If you go down the Q50/Q60 RS route, try to get a later model (2018) as the earlier models had issues with the turbos failing prematurely and it is $$ to replace as they are integrated into the exhaust manifold. The RS was available with or without DAS. Interesting, the only people that seem to hate DAS are those that have never owned one. Unless you want to track the car and value as much steering feedback as possible, then DAS is fine. Either the older version or newer (some on the US forums prefer Ver1) Retrofitting a VR into a V36 sounds like $$$ and you end up with a unicorn that may be hard to find someone to work on it and will make it harder to sell. Surely building and turbo charging a VQ37 will yield better results anyway.

Not exactly. Matic S is a newer fluid. Many Transmissions that specified J before S came out, can happily run on S, but they are not the same fluids (same with NS2/NS3 with Nissan FWD CVTs). For example, my Infiniti specifies Matic S for the transmission, but Matic J for the transfer case as it requires a higher viscosity fluid. Sorry, I don't know with any certainty if the RE5 can happily run on Matic S, plenty of forums and web pages say it can..

Matic S is a lower viscosity fluid, if the manual specifies J, make sure it will happily run on the lower viscosity S before you use it.

Out of your list, you haven't mentioned throttle body? how grotty is it?

Ok, wonder if that is normal?? Even my wife's bulky VQ35 AWD Murano does better than that, usually returns around 9L/100km on the highway. V35 6MT returns around 7.5L/100km and my current Q50 is mid to high 6s.

11L/100km highway? are you sure that's right? not 11km/L? as that seems quite poor for highway driving, my V35 gets better than that with urban driving.

They are probably using the 7sp auto from the 3.7 V37, which we also don't get here (not sure about NZ), we only got the 2.2t diesel, 2.0t petrol, 3.5hybrid and 3.0tt. Not sure if any of them are going to be suitable (3.5hybrid absolutely won't be).

yeah, it gets a bad wrap, and if you want to track the car, it probably wouldn't be ideal. But for daily road use, I prefer it to the steering on my V35 now.

Are you sure those documents are for a V37 and not a V36 with 4WS? There is certainly no rear steering components on My Q50S premium with DAS. the DAS system completely disconnects the physical connection between the steering wheel and the rack with just an angle sensor and feedback motor in the column, it does have an electronic clutch that can reconnect a physical connection there is a system failure, but with zero power assistance.

4WS in the V37?? Not in any of the AuDM models that I have seen. If you mean DAS, it isn't 4WS.

I would clean both MAFs and try standard filters and see how it goes. No point going down the tuning route until everything is working properly

sent you a PM

yeah, consult is the nissan tool that all dealers have, you can buy Chinese clones of this which do the same thing. There are other options out there beside Consult (can't say I have heard of anyone using the term 'consult' for devices other than the Nissan devices). I know the nissandatascan software can do the idle air volume learn among other things the basic OBDII tools cannot, but they are not on the same level as Consult. You need to buy your own adaptor though, their webpage lists compatible adaptors. http://www.nissandatascan.com/ You would need NDSIII for the V36

I have a consult clone, as Duncan said, you need to change the region to DOM. If they leave it set to Oceania, they won't get the option to select this model. Sounds exactly like the symptoms you get when you mess with the throttle bodies without doing an idle air volume learn. Very difficult to do it via the manual method. Consult or nissandatascan will do it. Mechanic sounds like they are spitballing..

It will only work if the fault that caused the light is no longer occurring. This process doesn't actually fix anything, it just clears the current SRS codes. If the fault still exists, it will just trigger the code again when the ignition is turned on next.

it is in the FSM.. FSM.pdf

You might not get to many replies since the V36 250GT wasn't eligible for import into Australia under SEVS. There might be some in NZ, but not sure if any owners are on here.. otherwise maybe try the US forums, the V36 chassis G25 should have the same transmission.

Always interesting to read about these 'road less travelled' projects, big kudos for taking it on! I have read a couple of VK56 swap stories and apparently it is a very tight fit, not sure if the 45 is a bit smaller? From what I have read, if you are after outright power, the LS swap is still the way to go, but have big respect for people who take on these different options! Given I almost certainly wouldn't have the patience to do it myself!

Yeah, although the V35 Skyline and the G35 share almost all mechanical parts. They aren't exactly the same, there are different options/features/specs, the G35 Sedan could be had with a VQ35 AWD, no such option in the Skyline. The G35 ECU complied with the OBDII spec as required by US law, the V35 doesn't as it wasn't required in Japan. As above, G35s were LHD only. The V35 never got the VQ35DE rev-up engine the G35 did. If it is a JDM vehicle with the steering wheel on the right side it is 100% a V35 Skyline, not an Infiniti G35. Nissan Consult 3 can read all V35 functions though, where as the V36 and V37 (Q50.Q60), need Consult 3+ to access everything.

I'm a little surprised there was an option to tune the hybrid. I thought the market was just too small and the difficulty of not just tuning an ECU, but the entire hybrid control system so it doesn't mess up the driveability. The Hybrid power control system needs to have a fairly good idea of the power/torque curve of the ICE so transition to and from ICE as well as motor assist and battery charge, is smooth and unobtrusive. They might also be a bit worried about the transmission as it is rated to 600Nm and with 547Nm in stock form, you don't have too much head room before extra work is needed there. Anyway, how did it go? much difference?

I see a lot more V35 Coupes than V36, not sure why either. it isn't like they were more common a few years ago, they have always been a bit rare compared to V35s.
