With all the big horsepower GT-Rs in the works it’s good to know someone is thinking about upgrades in head of these beastly VR38s. AAM have sourced these heavy duty intake and exhaust valves from Ferrea.

On the exhaust side, they’re built from Ferrea’s Nimonic90 Super Alloy which should be able to handle the heat even in the most extreme VR38 builds.

Intake wise, AAM selected the Ferrea Competition Plus Alloy valves as a solid upgrade over the standard items.

If you’re looking at a huge build, it might be something to think about and give Clint a call at AAM…

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.

Almost anyone who’s ever owned a turbocharged car before in their life KNOWS this. You need a bigger intercooler. Your factory ones do a job and is suitable for it’s intended purpose but as soon as you begin tuning you’re running into a problem. It’s simple and luckily most people get it. Air makes power, air goes in (intake) and air comes out (exhaust) and the cooler your intake air, the more dense the air is and the more power you make. Simple.

Remove some restrictions on both sides, better exhaust, less cats, better filters and more free flowing high performance intercooler and reap the benefits.

AAM has thus put the finishing touches on exactly what YOU need. Their new AAM Competition Intercooler for the Nissan GT-R has been fitted up in prototype form and it looks to fit the bill. Featuring a big volume increase by maxing out the use of available space, it still manages to bolt on in the OEM cooler location with no drama.

Looks pretty badass too. I’m sure we’ll be seeing pricing by the end of the week.

Thanks Clint from AAM!

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:

• AAM Competition I/C Pipe Kit w SSQV
• AAM Competition V.2 Intake Kit
• AAM Competition W/G Actuators
• AAM Competition GT800-R Bolt-On Turbocharger Upgrades
• AAM Competition FPR Gauge Adapter
• AAM Competition Oil Cooler Kit
• AAM Competition Exhaust
• AAM Competition 3″ Catted Downpipes
• AAM Competition 3″ Resonated Mid-Pipe
• HKS EVC
• HKS Spark Plugs
• Denso 800cc Injectors
• COBB AP – Custom AAM Tune

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!

More parts from Altered Atmosphere to show you guys today. Launched in late March I feel these need a bit more attention than we’ve given them so far. First up are the AAM High Pressure Wastegate Actuators, perfect for running more boost than the OE wastegate actuators can properly handle. To fully utilize the standard turbos these are a must. These are also adjustable via an adjusting arm and retail at the $595 mark.

Next AAM have a Intercooler Hard Pipe and BOV Kit. Manufactured in high quality polished aluminium, these intake pipes increase piping diameter, smooth air flow and look good doing it. Included is the twin HKS SSQV recirculating BOV kit. All included the price is $2,195.

Lastly we have the AAM Competition Oil Cooler Kit with Fan. This upgraded engine oil cooler provides superior performance to the standard item via an increase in core size. There’s the puller fan as well to provide a constant air flow through the cooler. All fittings and adapters include, this sells for $1,495.

Altered Atmosphere (AAM) has recently unveiled quite a lineup of desirable high performance tuning products for the Nissan GT-R platform. First up lets take a look at their exhaust range.

We have a pair of T-304 grade stainless midpipes to choose from, both featuring a cat-less design. A resonated version which increases exhaust flow on the GT-R while saving weight but eliminates annoying cabin drone. There’s also a non-resonated design for those after lowest possible weight with the least exhaust flow restriction possible. The resonator fitted mid-pipe weighs in at just 17.6lbs, a 12.4lbs weight saving over the OE item and the non-resonator version is lighter again. Tested on the dyno, these midpipes are good for between 15 and 22hp at the wheels. They’re priced at $795 for resonated for $645 for non-resonated.

Next up is a pair of T-304 grade stainless turbine outlet/dump pipes for the GT-R. Featuring either catless or street legal high flow cat version. One of the first such designs we’ve seen on the market outside Japan, these high flow cat dump pipes are great for those wanting to boost performance while keeping emissions in check. These are priced at $1,495 but a catless version is also available for those looking for maximum performance without compromise which is just $995.

Sound clips of all AAM exhaust products are available online at their website linked below.
