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.

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 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.

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.

SP Engineering have been busy, as early adopters of the GReddy Trust TD06H-20G twin turbo upgrade they’ve been testing and tuning at their California based workshop.

They’ve put together this sweet video to hype up some interest around this first of it’s kind install so I’m passing it on.

Looks great guys!

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.
