Supercharged Nissan 370z GT Edition
Discussion
Thought I'd do a little post as I'm hoping to change this car soon
Its a 2012 370z GT Edition 7 speed auto, the GT Edition was a limited run in 2012 to celebrate 40 years of the "Z" in the UK
http://www.autocar.co.uk/car-review/nissan/370z/fi...
It has a few goodies over the standard GT model ie reverse camera , more soundproofing and improved dampers , many of these things have become standard on the later models
This particular car was supercharged by the previous owner who used it as his daily driver. I bought it back in March as he wanted to change and I already had a 2012 GT Edition in white and was looking to supercharge it myself, it just made sense to swap so we did a deal
The Supercharger is a Stillen kit , this conversion is very popular in the US where of course the 370z is much more popular anyhow , if offers engine characteristics very much like the standard n/a car but a healthy increase in power, surprisingly its not much worse on fuel averaging out only 1-2 mpg different to the standard car. Servicing is pretty much straightforward the oil in the supercharger needs changing every 7500 miles I choose to do both the engine and supercharger oil every 5k as its cheap enough and the rest is the same as the standard car

The car has some subtle external modifications as well uprated brakes, suspension and other supporting mods, in addition the 7 speed tiptronic gearbox was sent to the USA and uprated to cope with the extra power and provide stronger, faster shifts when in manual mode.
The current mapping gives 469hp with a lovely flat torque curve of around 345ft lbs peak

Lovely car OP. Power is definitely something to be proud of. Looks really clean in white too.
Unless I've read this wrong, any particular reason why you want to change the car soon? Or do you just fancy a change?
Itchy feet mainly , I've only had this car since March but here is my last one Unless I've read this wrong, any particular reason why you want to change the car soon? Or do you just fancy a change?
So I feel like I've had it longer and its 3 years of white 2012 370z GT Edition ownership
Also I really miss a manual, we have three cars in the house and they are all auto's.

What is the reliability like with this kit? I have a 350Z HR which is offered the same Stillen hardware (effectively the same engine sans 200cc). I've been tempted by this kit, but chuckin boost into a high compression engine like this is asking for trouble.
Any issues so far?
This car has done around 25k with the supercharger fitted and I think it was the first 370z in the UK to be done, the only issues came from a poorly mounted oil cooler which was allowing hot air to be drawn into the maf and caused running issues, that was sorted a long time back , as I said it was a daily driver for all those miles and no issues at all. In the US there are cars that have covered well over 100k , although the Supercharger units benefit from a rebuild every 60-80k or so but thats not a expensive job around $500 Any issues so far?
Horsham Developments have fitted the Stillen kit to the 350hr as well with good results made around 450hp iirc, these are quite high compression engines but the boost is low only 8 psi and since the supercharger makes more boost the harder you rev it only gets that high at 7k or so , up to 5000 rpm its less than 5 psi
In the US turbocharged stock engines have run well over 600hp at the wheels, then you get to upset R35 GTR's

The VQ37 is stronger internally than the VQ35 and they are quite different engines the 35 doesn't have Variable Valve lift and is slightly lower compression.

Just looking at the engine bay, is the Supercharger kit non-intercooled? How do your intake temps look (if you've ever looked?) the intake temps on my supercharged Civic were ridiculous, almost in the 90's!
It has an air to water cooler, it has a radiator with a large fan mounted on the back, a 12 volt pump inside the passenger wing circulates coolant through thethis rad and into the plenum, this is fine for the road and occasional track use, some people who regularly track fit a larger radiator to help keep the temps down, the ecu will monitor the intake temps and will go into a limp home mode if they get too high over 65 iirc and also warns if it has to start pull timing. Heat soak is the biggest issue so if the car has been stopped for a while i take it steady but once moving the temps drop to around 20-30 degrees over ambient
The kit was designed in So Cal so UK temps dont cause a lot of issues
I am quite interested in the interchiller idea where they use the cars a/c system to cool the charge though
The problem with fitting the larger charger coolers or fitting an air to air kit (both are available) is you need to chop out the bumper bar and I'm not willing to do that
