Yes, as a matter of fact, one certain GT-R does exist.

A 2 liter, direct-injected, turbocharged four-cylinder is going to carry the GT-R through the Japan Super GT series. This. Is. Wicked.

Carscoops wrote:For the 2014 season of Japan’s Super GT series, technical regulations (excluding engines) have become partially aligned with those of the DTM (German Touring car Masters), which means Nissan has to modify the GT-R Nismo racer to comply with the new rules.

All cars competing in the series will have to have common monocoque, transmission, brakes, dampers and fuel tank.

Competing in the GT500 class, the Nissan GT-R Nismo GT500 looks as fierce as one would expect given its name, but differs significantly from its road-going alter ego in the engine compartment.

While the street-legal GT-R Nismo is powered by a 592hp (600PS) 3.8-liter twin-turbocharged V6 engine, the GT-R Nismo GT500 sources its power from a turbocharged direct-injected 2.0-liter four-cylinder unit codenamed NR20A.

Nissan doesn’t say how much power this unit produces, but judging from the way the engine pulls it’s obviously more than enough to wow spectators. Furthermore, the racing GT-R Nismo is rear-wheel drive and should be a lot lighter than the road-going model.

Who's for an engine swap?

I wonder if this will share its basic construction with the DIG-T R in the ZEOD, with 4 cylinders instead of 3.

Welcome to NICO! I am going to do a but more digging but it sounds like the same design philosophy at least.

What I look forward to is, especially with the ZEOD's engine, this technology making it into production cars in some form.

I am hoping the two are similar in construction. If you look closely at the ZEOD engine, it is clear that they are using a unitized head and cylinder block with a separate crankcase.

The last time we saw that configuration in auto racing in a meaningful way was with the Offenhauser (aka, America's greatest racing engine). If you throw in the Miller it was derived from, it dominated American open wheel racing for half a century. From my understanding, the configuration is inherently lighter/stronger and more reliable. If you think about the forces at play and the cooling needs, splitting the engine so that the combustion happens in one piece of the engine and the conversion of reciprocation to rotation happens in another just makes more sense than splitting the combustion chamber.

However, it is more difficult to cast and machine and you basically have to take the engine apart to access the valves, so the configuration largely went away in the late '70's. However, now that we have computers to control the machining and engines have become more reliable, many of the drawbacks are no longer as significant. It would be awesome to see this configuration come back with all the latest technology and finally make it into a mass-produced engine.

I also have a feeling that the ZEOD engine could actually make more HP than what they listed if they took the limiters off, as endurance racing engines tend to run a little conservative. Add in the greater balance of a 4 cylinder, and a 2l of the same configuration could make some serious power.

Fantastic insight. That's a very interesting video.

still no details on the engine, but based on google translate, this is going to be a fast car

Afternoon free practice of manufacturers test the first day, mark the 290km / h machine platform is of GT500 class most in the road surface temperature rises. GT-R vigor topped the Among them, race a high speed of this season is expected. 23 MOTUL AUTECH GT-R # has finished the manufacturer test the first day of the fourth fastest in the GT-R urges top-level result. What deployment or waiting tomorrow.
You will be able to greet the opening game with a good result I'm sure.

all 4 GTR teams (12, 23, 24, 46) are in the top 5 cars in testing

Excited to see more details come about with this thing. Pretty awesome engineering.

So...who's up for a trip to Japan to see that guy in action?

I'm in! And welcome aboard!

Pretty sure I know you from somewhere.........

I'm in too (wife is a flight attendant and I fly for free...). Do you have an inside track on getting behind the scenes access? Really want to check out that engine.

Maybe it's due to us being friends since we were little kids? haha

haha I wish! That'd make for a hell of a vacation. You really can't go wrong with a turbo'd four banger.

These cars are fast. Much faster than the previous V8 cars. All of the GT500 cars qualified seconds faster than the previous course record, which dated all the way back to 2004. I really want to take a look at that engine...

(forgive my video posting, hopefully one of the links below will work)

BTW, it looks like a good option for a race if anyone wanted to go would be Suzuka over Labor Day weekend. It is a 1000 km race and tickets are 5700 yen (about $50) on sale Jun 21. Staying near the downtown Nagoya train station (about 50 min from the track via JR) seems pretty reasonable (under $100 per night).

That sounds totally awesome...too bad there's this pesky trouble of me getting a plane ticket to Japan (plus the leave I'd need to use from work). Darn that trip to Europe I'm taking over Christmas later this year.

So the GT500 GTR's took the first 3 spots in qualifying. Now that weather is looking better, we should get a better idea of how they do in a race. I really want to get a look at that NR20A...

The GT-R also took the top qualifying spot in GT300, so it is shaping up to be a good weekend for Nissan. Does anybody know where you can watch Super GT races here in the US?

Fuji Speedway GT500 RESULT: Total

So the Calsonic GT-R went from pole to win the race. Was watching the highlights with Talladega in the background... wish we could watch Super GT (translated) here

Looks like it runs on JSports 4. Anyone know a safe site to stream it on?

Kind of crazy to think about 4 cylinder GT-Rs in GT500 and with V8 Prius in GT300

Is there not a way to watch streams of the GT races here in the US via the power of the internet? Translated or not, it'd still be pretty cool to watch a race like that.

The GT500 GT-R's swept the podium last week. That NR20A must be quite the powerhouse. Still waiting for Nissan to give us a look under the hood.

So, the #23 team just won the GT500 championship... I really want to see that engine.

Wow...

I wonder why it's so seemingly hush-hush?

I came across some images from a couple of Japanese magazines



From Motor Fan Illustrated


Pretty low resolution and not available for google to translate the text. According to someone on another blog, the Motor Fan puts the output at 590 hp... which is pretty impressive for a compact 2l 4 cylinder. These cars also qualify at Fuji faster than WEC-spec P2 cars and only slightly behind the LMP1-h cars, meaning they are also faster than the IMSA cars here in the US. It is hard to tell much from the images, other than this looking like a very compact engine, probably a stressed member, optimized for low CoG, etc. Too hard to tell if this shares the unitized block and head construction with the ZEOD.

If it's a 4 liter four cylinder, ok.

Whats the snail in the lower right? Roots oil pump?

It really is very impressive. State-of-the-art technology for true GT-R.
