MGAWOT II: A 1500hp GT-R Street Car That Runs 8s

Getting a 3700lb (1675kg) Nissan Skyline GT-R down the strip in eight and a half seconds flat on its very first outing since an intensive, yet short lead build, is not any way, shape or form an easy proposition. But behind the wheel of MGAWOT II, New Zealand-based but internationally-renowned Nissan RB-series engine builder Robbie Ward has just made it look effortless.

If you know anything about GT-R drag racing you’ll probably recognize Rob’s name. If not, you should recognize his company’s, because for the last decade that modest workshop in a small city at the center of New Zealand’s North Island has been turning out some of the quickest and fastest Nissan RB-engined street and drag cars on the planet – many of them for international customers. The Bayside Blue BNR34 – unofficially dubbed MGAWOT II – is arguably their greatest work yet. It’s certainly the most powerful Skyline to have ever emerged from the RIPS (aka Rotorua Import Pro Shop) lair.

I caught wind of the Skyline-based drag project earlier in the year, not long after RIPS blew everyone away with its original MGAWOT machine – the company’s own Nissan Stagea station wagon which ran a 9.0-second pass on its very first pass down the strip and high eights ever since. MGAWOT II promised that and more, and during the course of last weekend RIPS delivered on its word in more ways than one. Not only did it a turn an 8.64 ET and a new NZDRA national class record on its debut run off the trailer, but it backed it up with a succession of 8.60s, then an 8.57, and finally an 8.51 at 162.5mph for the IHRA drag national class record too.

For the sake of anyone wondering, MGAWOT is a play on megawatt, which in power terms equals 1000 kilowatts, or 1341 horsepower. Truth be known, MGAWOT II has a little more than that, and more impressively makes its power on off-the-pump E85 biofuel. Equally remarkable, just seven short weeks ago the GT-R was nothing more than a rolling body fitted with a roll cage and a parachute. It arrived that way from the UK, but now, a couple of days after its debut racing weekend, it’s locked up in a shipping container and on its way back.

It’s not the first Skyline that’s been sent halfway around the world for Rob and his team to work their magic on and it’s unlikely to be the last. When it comes to RB engines – custom-engineered RB30s to be precise – RIPS has an enviable reputation. But it didn’t come by chance. Rob isn’t the sort of guy to ever shy away from a challenge, and he certainly doesn’t do things by halves. Too much power is seemingly never enough for this guy, and if that custom humped vent on the hood doesn’t speak volumes in that regard, lifting it up certainly will.

Like all of RIPS’ high-power builds, MGAWOT II’s engine is RB30 based. In this instance though, it’s pushed out to 3.2 litres courtesy of a Nitto Performance Engineering stroker kit featuring a 4340 billet steel crankshaft, 4340 I-beam rods, and a set of JE/Nitto forged T6 2816 alloy pistons. Not only do the upgraded internals give the engine the strength it needs to handle high horsepower loads, but they also allow to it to rev more freely, and to a 10,000rpm-plus altitude.

Of course, to achieve those big numbers you need a cylinder head that’s equally up to task. RIPS’ close associate Kelford Cams got that job of delivering a race-prepped and fully-flowed head from a brand new RB26 casting. On the subject of flow just look at that beautiful hand made intake plenum that the compressed air blows through.

Then there’s the turbo: a Garrett GTX47-series compressor sitting on a custom-built tubular manifold and running a pair of Turbosmart PowerGate60 wastegates. To give you some reference for size, that heat-wrapped pipe running out the back measures five inches in diameter. Large? Yes. Scary? A little…

If the engine was methanol-fueled and not destined to be street driven, the package could have sufficed without the need for an intercooler, but seeing as it’s designed to run on E85 and will soon be put back on the road in the UK (yes, you read that right!), a custom-built water/air charge-cooling system has been employed.

The set up pumps ice cold water stored in a custom designed and fabricated 50-litre boot mounted tank, through hoses to the ARE intercooler behind the front bumper. According to Rob it’s working perfectly to keep the intake temperature in check. The 18-litre tank on the left-hand-side hold the fuel, with a trio of Bosch Motorsport 044 pumps feeding the supply to the engine through six 2500cc injectors.

That’s not the only fuel the engine feeds on, though.

RIPS has always been a big fan of N2O, and while the Nitrous Oxides Systems set-up has the ability to deliver multi-port shots in the future, it currently only operates a small fogger nozzle for a 75hp hit that’s primarily used to bring the engine up on boost.

Remember what I was saying about attention to detail? It’s evident wherever you look, right down to CNC engraving on most of the custom-made items. The Tali Lomu insignia came at the request of the car’s owner – a huge rugby supporter with an immense respect for one of the sport’s most revered players of all time. New Zealand All Black great Jonah Tali Lomu, himself the owner of a couple of fast GT-Rs, was well known for his ability to steamroll anyone who got in the way of his 6 foot 5 inch, 280lb frame, so it’s a fitting name for a car that’s been designed to mow down the competition on the 1320.

With a conservative 1500hp on offer the RB32 definitely has the credentials to get the job done, but what surprised me the most though is how civilized the overall package is. Off the trailer all it took was one twist of the key to fire the engine into life from cold start before settling at a raspy, but even idle. Maximum effect, but minimal fuss.

That mantra follows through to the driveline, where alongside reliability, ease-of-use and driveability are key design traits. Unlike previous builds where OS Giken OS88 six-speed sequential gearboxes have traditionally been RIPS’ transmission of choice, MGAWOT II benefits from a ProMod-style two-speed, manually-shifted automatic that’s been significantly modified to integrate with the GT-R’s four-wheel drive underpinnings. The idea behind the auto transmission, which was initially developed in the Stagea, was to remove driveline ‘shock’, where immense torque loads plus a hard launch can equal expensive breakages. In a complete turnaround from the accepted norm, this GT-R catapults off the line smoothly, and even more surprisingly with just 6psi of initial boost pressure.

Getting the car out of the hole and on its way to a eight-second slip is a simple proposition Rob tells me. Looking at the left side of steering wheel, the top button purges the nitrous system while the bottom one engages the transbrake. On the right-hand side the top button activates the Leash Electronics Bump Box, while the bottom button triggers the N2O.

To heat the rear tyres before a run, a manual torque split controller alters the drive from full four-wheel drive to rear-wheel drive and can be adjusted to anywhere between.

After the burnout, the lever with the blue button is pumped back and forth to reinstate pressure back into the system and four-wheel drive for the launch.

That Bump Box I mentioned a couple of pictures back is a useful device in a set-up like this. To trigger the second set of staging lights, a driver normally has to be off the gas pedal to inch forward and fire the beam, which only leaves a split second to rebuild boost in time for the lights to drop. With the Bump Box, a microprocessor in conjunction with the transbrake does all the work, allowing the car to ‘bump’ into stage without the engine having to come off boost.

On the subject of boost, this is the first time RIPS has employed a CO2 system in one of its cars. The technology, which utilizes air regulators, is perfect for this application where boost control is critical, and pressure needs to increase as the car makes it way down the strip.

That said though, with its current Link G4 Xtreme engine management system tune the big RB’ is only operating at around 85 percent of its ability according to Rob.

It doesn’t take a genius then to work out that this car has a lot more in it yet, and that’s before you even start thinking about removing weight, like its heavy electrics-equipped steel doors and factory dashboard from the equation. It’s also running old circuit-spec coilover suspension, and the list goes on… Seven second potential? Without a doubt.

In the meantime however – if its debut performance is anything to go by – the Skyline should be at the top of the game when it hits up the Street Class of Santa Pod’s Jap Drag Racing Series, which coincidentally just kicked off for the 2013 summer season at the same time MGAWOT II was being shaken down in a far away land.

Given New Zealand and the United Kingdom’s geographical divide, chances are I’ll never get to see this car run again, and that saddens the inner GT-R worshipper in me. At the same time though, I know for a fact that this won’t be the last fast Skyline from RIPS, and that said, I can’t wait to see what Robbie and his team cooks up next. MGAWOT III? Watch this space…

I live in the California. I've literally only seen an R34 GT-R on the street once in my entire life, let alone one with 1500hp. You may be sad but I've been crying since I was old enough to realize that I'd never be able to own one as long as I live in California (which I intend to). I'm crying as I type this too, btw.

Fantastic ride! I would kill to see this running in a drag event in Romania, but my country has the automotive culture of Narnia -- although it has the potential to develop some amazing tracks, circuits and racing strips (all that open terrain could help, alot). 

 

Awesome car and article. Thank you, Speedhunters :D

It is a nice ride. I am just guessing  the local government must not have emissions standards..  Also,   how well does a two speed transmission act while doing 30-55 mph ? must have to have ear protection.. Love the gas tank as well..  hope you have stock in a fuel company..I really wish the "STREET CAR"  term was more clearly defined..  years ago to be registered for a show or race class, "STREET CARS"  had to have verified mileage.   i.e  oil changes, tires, brake services..  how comfortable would that car be driving 15-25 miles a day or like 15,000 miles a year.   I am just saying. STREET CAR . na

I appreciate the build and all the research and money that has gone into it, but why oh why would you then skimp on a cheap ass Jamex bucket seat. Especially in an 8sec car. I would rather the factory buckets than some imitation poor quality Jamex seat.

Great build, but seems to be handicapped by its weight?

As far as fast RB's go, it seems as though they've started with an odd chassis. I imagine this cars got more in it than an 8.51, but without even particularly following drag racing, I can think of many faster RB30-powered commodores - the RB30's real home.

 

http://fullboost.com.au/records.php?class=1

A quick search showed 6 VL's doing sub 8.5's, with 5 of the 6 still being SOHC RB30ET setups (with one being a 26/30 like this one). The top-20 all do less than a 9s pass..!

 

Cool to do something different though I suppose, and Id guess a drag-GTR has a bit more appeal in the UK..

I wouldn't exactly call this a street car...  AMS Alpha 12 GT-R, now THAT is an 8 second street car.

Seems to me John Sheppard ran 7s in his street legal awd talon a decade ago with much less hp - this seems to be a case of the wrong platform taken to it's extreme IMO

pretty cool. but i would never hack up a r34 like that or any r for that matter.

Always been a fan of Rob's work. Great to see he continues to think outside the box and come up with these crazy drag cars...for equally crazy UK customers!

i always  thought the r34 was a little lighter than 3700 pounds. i always thought it was like 3400 or 3500.so for a r35 to weigh in at only a hundred pounds more is impressive considering the changes they have made between the r34 & r35. wow learn something new everyday. this is a nice build. funny i never thought the day of 1000 hp builds would be normal. that turbo is a nice piece of work. good article once again.

What's at the rear of the left-hand side valve cover? Looks like a vent of some sort...

 @HR32 They where put on as the set up is much lighter than standard units.  Stopping can be interesting though. They are good for one 'big' pull up but would not manage a lap of the track without overheating and going AWOL.

 @KevinWonderly This car has been built to run in the 'JDS Street Class' of the Jap Drag Series held at Santa Pod. As such it has to carry a valid registration and license plate as well as meeting other requirements like having a complete dashboard and door panels etc... So yes, although it's not the sort of car the owner is likely to drive everyday, it will be street registered – and from what I've been told – street driven sometimes.

 that seat is out of our Stagea and just put in there for the day because it was more comfortable for me, the seats that are in it now I'm sure you would give a big stamp of aproval :-)

The chassis was chosen because thats what the customer wanted, it was not chosen because he wanted to be quicker than anything else in particular, just he wanted a fast R34 GTR.  We've done 7.8s in a 240z that weighed more than probably all of the VLs your talking about but at the time we didn't chose the 240z because it would be quicker than a VL, we chose it because it was different and cool.  Add 500kg to the top VLs on the list and see what times they do then :-)

BradLord
BradLord

 @RdS2 Of course a lot comes down to the chassis, and those front-running VLs aren't just RWD – they have BIG tyres on the rear too. If you want to go really fast though, you put in RB30 in a rail car, which is what RIPS did a while back. That FED was not only the first RB-powered machine in the world to run a 6, but it's still the quickest and fastest I believe.

 @Nicky89 ah thats where you are getting confused nicky89, the car you are talking about the AMS Aplha 12 GTR is not a skyline, the last of the skylines was the R34 as we all know.

The platform is the one the customer chose because he wanted it, it was nothing to do with chosing what would end up the quickest, not everyone will chose the same type of car thankfully and some will for sure have advantages over others but how boring would it be if we all built Talons??  I bet the Talon didn't weigh anything near 3700lb's either. :-)

 @hanablemoore What @lalandeusse said is correct, there's quite a bit of extra weight here. The intercooler system –including the unit, plumbing and tank filled with ice water – weighs 220 pounds (100kg) alone. The only reason they found out how much the car weighed was because it had to be put on the scales after claiming it first national drag racing record during the weekend.

 

lalandeusse
lalandeusse

 @hanablemoore The reason this one weighs 3700lbs is because of the huge modifications, and the lack of serious weight reduction. A stock R34 GT-R weighs about 3400lbs.

It's a vacuum regulator for the crankcase, it's needed because of the dry-sump system.

Rotaries yes, real RBs no.  Quickest RB30 is from NZ, quickest GTR is from NZ, worlds quickest proper RB is from NZ too.

A RB30 is not named based on the head used, its named based on the block type used and its displacement so no matter what head it has it's still a RB30. This one uses a twin cam head.

 @H05TYL It would take a lot to bring it back to stock. For example the dash.
