**I would've posted this in the Next Skyline section but I thought it was too special.

At the New York Show it was revealed that a V36 Skyline Coupe Convertable is on the cards for a 2009 release, at the very least as an Infiniti in the US, with a domestic Japan release as yet undecided. Not since the Prince Skyline Sports of 1961 has there been a Skyline Convertable of any sort:

Yes it's just CG but it gives a good idea of what to expect.

The convertable will obviously be based on the V36 Skyline Coupe, but with updated running gear as the Series II V36 will be scheduled for sale by then. One other ineteresting thing is the engine, a VQ37*VHR* from the Coupe, with a new VVEL 'electric motor driven camshaft switching' valvegear... more on this later when I get a chance to fully translate the article. The new engine is more efficient, produce less emissions, still have the high response of the current VQ35HR, and have higher capacity and torque to boot. I don't know, but this seems like the last hurrah of the conventional petrol engine for some reason...? Theres ALOT of technology going into it and theres not a turbocharger in sight... more later.

*Edit: The VQ37VHR is even more environmentally friendly than the current engine, but with even more response and torque right throughout the rev range. Reduced 'pumping loss' and reduced total exhaust emissions, with CO2 reduced by 10% aswell make this a very green enigine but still producing 330HP. Internal friction is another area which has had even more attention paid to, resulting in even higher response and acceleration which is sensitive to even minor throttle input. these points were touched on but not divulged completely, so more and more information about these improvements will be cleared up later in the year.

**Edit: VVEL DC motor controlled camshaft profile prounced 'Vee-Vell'

A DC motor is connected via threaded shaft to a 'control shaft' with a rocker arm attached, which then, via a link (shaped much like a conrod) moves another driveshaft which is positioned side by side to the previous mentioned 'control shaft'. The driveshaft had cam lobes positioned along the driveshaft, but are able to spin around freely on it, their profile is governed by the position of the driveshaft in relation to the control shaft; either being positoned closer or further away from it. What this essentially means is that the 'cam profile' is infinitely variable... there is no cam switching here, nor is there a 'switching point' or limits to the the camshaft profile (within reason). Variable Valve Event and Lift system or VVEL. My translation wasn't so good so... Check (if you live in usa): Publix Weekly Ad, or Big W toy catalogue.

The VVEL page... sorry the flash covered the diagram with the electric motor mechanism and cams.

love it how nissan is finally looking into camshaft switching!!!

next step is 3d profiled camshafts - bring on ferrari technology!

on a downside - i can see this messing with alot of aftermarket turbo/tuning options.

      I also just ordered some Frankenstein bolts and side mounts to fit a hard top Just in case I do find one, basically so it doesn't need to be fixed to the car with only the front latch.......and then gaffa tape to keep it in place for the RTN journey from wherever I get it

      If your temps are fine now, you probably won't have any issues with where your vents are as they don't look right up at the windscreens high pressure area, so any differences when giving it the beans for extended happy laps would be minimal, but, they should vent heaps when stuck in traffic  Much like how that reverse cowl on my SS let "visible" heat out when stationary, but, because it was basically at the windscreen my coolant temps on the Hwy actually raised because air was being fed into it at speed (110kph), to only come back down to around 90° when I got off the Hwy And your 100% correct about the NC currently not needing vents, but, if I was to add a turbo, and a oil cooler and intercooler in front of the condenserand radiator, and then take it to the track???? It is apparently a recommend requirement if I don't want to worry about coolant or oil temp issues, but, any of the above are possible scenarios, over time As it sits now, with the triple pass radiator and stock air conditioning system, I have absolutely no issues with either temps or air conditioning efficiency, I've been basically daily driving thie car for the last month, both on the Hwy, and peak hour, bumper to bumper traffic, but, that's pretty much expected from basically a standard engine  Talking about no issues daily driving, it was 39° the other day and I was sitting in bumper to bumper traffic on the M5 and then M7, with the top down, and with the air conditioning blowing nice cold air on my feet, balls, and face, well, there was one issue, my head and arms got pretty sun burnt Note to self: leave a hat and sunscreen in the car for such days 🤣

      I would agree, unless you need something specific to the HV motor/battery side repaired or investigated, any mechanic will be able to perform normal services, but if you prefer, maybe look for a mechanic who regularly services/repairs Nissans, the VQ engines are pretty common in the Nissan lineup.  Sorry, I can't make any suggestions, I don't live in Vic.

      Some of them keep working fine. 9 out of 10 of them end up causing an absolute misery bleeding the system and get thrown on the workshop floor in a tantrum and never thought about again because they were never really needed and just added crap to the car that we could have done without. Same-same with HICAS, A-LSD, and various other stupidities that over eager 10x engineers thought we had to have.

      Not required but appreciated. Super Coppermix Twin even the non-competition model feels like the pedal is noticeably heavier than stock which was pretty well judged IMO. I'll be swapping in the Nismo operating cylinder soon to see how that feels.  Personally I haven't felt anything that justifies replacing the damping loop, at least compared to more modern stuff where the clutch delay valve is actually quite noticeable.
