GReddy TD06-20G Twin Turbo Kit by SP Engineering

May 9th, 2010

Great new video from the guys @ SP Engineering who’ve been busy building up some tough GT-Rs, the fastest ever down the drag strip to be precise.

Good enough for mid-9s down the quarter mile, matched with the right fuel setup this will leave you with a potent street or track car.

Two More GT-Rs Run 9’s and New Records All Round

April 13th, 2010

A huge day for GT-R drag racing enthusiasts with not one but two more GT-Rs entering the mega exclusive 9 second R35 GT-R club.

A lonely club it was for the single GT-R in it until today when SP Engineering smashed the record and dug deep into the 9’s with a amazing 9.62 @ 150.75mph at SpeedWorld drag strip in Arizona, USA. That is seriously moving.

It was quickly followed by NAGTROC member Hing (rsfootball) who had an amazing day as well running back to back 9’s with a best of 9.8 @ 148mph.

Both of these cars feature the GReddy TD06-20g twin-turbo upgrade kit and were running the 18″ drag radials on Volk TE37 wheels for the best runs.

The SP Engineering car also has further modifications to the engine including:

  • GReddy Intercooler
  • CP Pisons with coating (standard sized)
  • Carrillo Conrods
  • 1000cc Injectors
  • SP Engineering Fuel Pump Setup w/FPR
  • TiTek Titanium Race Midpipe
  • TiTek Titanium Race Exhaust
  • Cobb AccessPORT

With all that said though, the clutches remain stock. You can actually check out their massive engine overhaul photo thread on their website here for pics of the engine components.

Hing’s car on the other hand is slightly milder, while it does have the same GReddy TD06-20g twin turbo kit, its still running standard internals… Yep a standard motor, upgraded fuel system, Cobb AcessPORT, GReddy Titanium Exhaust and Dodson Motorsport/Exedy upgraded clutch packs! There’s more to it than that but I’ll let Hing decide if he wants to divulge the rest over on NAGTROC

On this setup, and his own 20″ drag radials, he was running back to back 9.9’s. It was when he switched out to the 18″ drag radials that he dipped into the 9.8’s.

For these runs, both cars were running C16 fuel the track temps were around 120° F and air temps were about 80°F.

Congrats to Hing, SP Engineering and everyone involved in this huge success!

HKS Unveil New Turbo Lineup – Nissan GT-R Full HKS Turbo Kit Inbound

February 7th, 2010

HKS Premium Day was held just over a week ago now and it wasn’t all about on-track festivities. HKS also had an entire new turbo lineup to unveil. This is their new inhouse designed turbo lineup known as the HKS GTII.

Due to be released in March this year, HKS are also developing a full turbo kit for the Nissan GT-R that will utilize these turbos matched with a HKS exhaust manifold to directly compete with the current Trust TD06-20G kit that has been out for some time.

SP Engineering Stage 1 SPE750 Turbo Upgrade Package

November 16th, 2009

SPENGINEERINGTURBO7

SP Engineering have announced their own 750hp+ stage one performance upgrade for the Nissan GT-R based on their SPE750 upgraded turbochargers. The turbos, based on standard IHI ones, are honed out and have their internals replaced with ball bearing type cartridges. There’s an increase in the compressor and exhaust wheel size but this is probably countered by the improved ball bearing design to maintain response.

The package also includes JET coating on the integrated exhaust manifolds. This will help keeping heat out of the engine bay and in the exhaust. This keeps exhaust gas temps higher and improves gas flow. Obviously it also takes heat out of the engine bay as well which benefits the cooling system overall.

The full SPE750 package will consist of supporting modifications to help owners get the most from the turbos including 800cc injectors, upgraded fuel pressure regulator with lines, upgraded dual 255 litre/hour fuel pumps.

A HKS GT570 kit is included as well to cover the exhaust, intake, boost control, ignition and wastegate control side of things. To control all this, owners will be supplied with a Cobb AccessPORT map specifically for the SPE750 setup.

MSRP for the full setup is set at $18,500 installed.

For those wanting to push the GT-R even further, SP Engineering have a GReddy TD06-20G twin turbo based SPE900 kit as well but pricing is yet to come for that.

AAM Competition GT800-R Turbo Upgrades for Nissan GT-R – The Results

September 26th, 2009

aam-turbos-002

I think you’ll remember back to when AAM launched these GT800-R turbo upgrades and may have been wondering how they worked out. AAM have completed not one but two customer cars by now and have gained quite a few more datapoints to back up their original test data.

You can check out the full build details over on the NAGTROC thread but the basic rundown is, with the AAM GT800-R turbo upgrades including supporting modifications the guys have made 708awhp and 623 lb/ft of torque on 100 octane gas. One point to note is that this beast maintains street legal status by way of a set of AAM high flow cats. You can watch this car on the dyno in the video below.

To back it up however, the guys complete a second turbo upgrade with a focus on being able to use pump gas. The results are suprisingly similar making 675awhp but a huge 651 lb/ft of torque. More torque than the car on 100 octane all from ordinary 93 octane gas.

Whats next for AAM? Well they’re currently tearing down a perfectly good VR38 engine to rebuild with stronger internals. We’ll be following this very closely as it will be one of the first and, at least so far, the best documented VR38 build to date.

Hit up the AAM website linked below if you’re looking for some more information and pricing on these upgrades.

Thanks Clint@AAM for compiling all the info and for the GT-R community input in general.

Mine’s Release Cam Shaft and Titanium Straight Pipe Upgrades for Nissan GT-R

September 21st, 2009

mines-camshaftproII-001

Mine’s continue leading the way in terms of GT-R engine tuning with the release of their latest hardware upgrades. The Mine’s Super Camshaft Shore PRO is a full camshaft replacement for the VR38DETT designed to unleash the full potential of the engine in terms of response and power.

The Mine’s camshaft profile on the intake side is 256 degree duration with 10.2mm of lift. On the exhaust side there’s 264 degree duration with 10.5mm of lift.

Compare the Mine’s camshaft profile against the standard item which is 238 degrees / 9.56mm on the intake and 248 degrees / 9.88mm on the exhaust and you can see that the Mine’s set will clearly breath better.

These would ideally suit someone already running / considering turbo upgrades but even on the standard turbos you would see a concrete improvement once tuned. They’re full drop in replacements for both GT-R and SpecV GT-Rs.

Update: Pricing for the Mine’s Camshaft set is 138,000 yen.

mines-straightpipe-001

Next up Mine’s have also released the final word in lightweight titanium midpipe for those who are chasing the ultimate response and power from their GT-R.

The Mine’s Titanium Straight Converter for Nissan GT-R removes the secondary catalytic converters and replaces them with two small resonators. The final weight reduction over the standard item is 9.8 kg (3.6 kg vs. 13.4 kg). The main pipe sections are 70mm into a pair of 110mm resonators. Then via dual 70mm pipes into a single 80mm collector.

Fitment is a simple bolt on affair and pricing is to be announced shortly. Again, stay tuned to the new Mine’s website for more details.

Update: Pricing for the Mine’s Titanium Straight Converter is set at 210,000 yen.

Trust and Garage Saurus: GReddy TD06-20G Kit Dynos 834ps @ Wheels

August 12th, 2009

saurus-trust-834ps-002

We’ve been following the progress of the Trust GReddy TD06-20G turbo kit for a while now, thanks to Garage Saurus, and today we’ve learned cold hard numbers on what the kit can do.

On Trust Japan’s dyno, running 22 psi of boost and completely maxing out the Bosche injectors they’ve managed to pull off a 834ps (822hp) run at all four wheels. Other components upgraded for the run were the intercoolers, utilising the Trust GReddy Type06-R Intercooler kit.

Quite an upgrade from where they started with “just” the 650ps output from Garage Saurus original basic performance upgrade components back in January.

Willall Racing Release Turbo Upgrades and Beefed Up Gearbox Parts

August 9th, 2009

wr35tt3

Willall Racing are stepping into interesting territory with the release of their latest upgrades for the Nissan GT-R. So far Willall have been focused on lubricating and cooling the GT-R to prevent untimely wear where possible. This time the goal is much more focused on producing power.

At the core, the upgrade consists of larger compressor wheels, 6mm larger to be precise, and larger turbines, 9mm bigger there. Whenever you hear “bigger” with a set of turbos you automatically think of lag and the big “Will these be laggier than standard?”. To answer that, Willall will also be replacing the standard plain bearing core with a full ball bearing item for overall similar low end power delivery.

Willall’s turbo upgrades are inspired by those Nissan made to the GT-R for the SpecV and they say that power output with a set of these fitted could be increased as much as 100awhp. We’ll know more data after they’ve compiled their data.

Right now these are still in the testing phase but pricing and availability details will be posted when we know.

Increasing the GT-R’s horsepower should be considered carefully because once you get hooked on the power you’re going to start wanting to strengthen the drivetrain to ensure reliability. Willall have you covered for cooling and lubrication but other weakpoints are being handled as well. The WR35CC GR6 Gear Fastener set is a set of three replacement clips for those that Willall have seen failing on GT-R transmissions.

According to Willall, the factory circlip, which essentially holds the transfer gear secure on the shaft is of questionable suitability for the task. So they drew on their motorsports experience to improve on it.

While the replacement does require remove and refit of the gearbox, it makes sense for anyone replacing their gearset or performing any other extensive gearbox work to do “while they’re there”.

Priced at $370 it may very well be cheap insurance against a terminal failure.

AAM GT800-R Turbo Upgrades Arrive With Test Data

July 23rd, 2009

gtr-engine-001

After just completing the engineering and testing phase of the new AAM 800hp turbo upgrades for the Nissan GT-R the guys have announced they made 659 hp at the wheels on just 19psi of boost on pump gas! Youch that’s a lot of power. What’s more is that the guys had only just begun to scratch the surface of the potential here and are expecting 700awhp by the time they’re done.

Fitted to the first AAM 800hp Turbo Upgrade Nissan GT-R was the following supporting modifications:

Note that AAM actually opted to go for high-flow catalytic converters instead of a straight through exhaust like many would. Interesting choice and it shows their cat’s design is solid for sure.

Next up from AAM is a competition intercooler setup as the stockers just aren’t cutting it at 700hp and I’m not surprised!

Check the dyno chart below and head over to NAGTROC to see the dyno run videos.
