The build up of this monster Godzilla is not being rushed in any way. AMS have gained their solid reputation from doing things right and so, in that tradition here’s their progress so far.

Last update we showed you how they used a co-ordinate mapping machine to map the inside of the GT-R engine bay. This was done so they could correctly size the turbo, manifold, wastegate and downpipe configuration to completely maximise the available space. Since then they have spent a lot of time at the CAD software designing how the manifolds will meet all of their design goals like:

• Completely equal length
• Port matched
• Smooth transitions
• Ease of manifold bolt access
• Cast in 304 stainless steel

They finished their preliminary design earlier this month and so it was time to move to the fitment testing part of the project. AMS use a plastic composite mock up of the complete part. This is printed in a sophisticated 3D printer by building up layer upon layer of plastic material to slowly build out a exact size replica part within a very tight tolerance.

Once out of the printer they can actually bolt this up to the car to ensure their design matches reality and that it truly will fit into the car. This is the next steps. As you can see in these photos it’s already bolted up to the VR38, next step is to drop the motor in the car and check if the custom heat shields bolt up as planned.

If everything checks out, AMS can organize to have the part cast in stainless steel. Once that is done then they’ll have the moulds for production for other customer cars.

After just the right amount of anticipation, Tomei has joined the Nissan GT-R camshaft party with their own range of upgrades under the Poncam brand. Well respected in the tuning world forever, the Poncams are a drop in replacement for the standard items.

On the intake side, the Poncams increase duration to 256° and lift to 10.2mm with a initial lobe center angle of 124°. On the exhaust side the cams feature a 264° duration and 10.5mm of lift. Initial lobe center angle on the exhaust side is 115°. In comparison stock ones are 238°, 9.56mm intake and 248°, 9.88mm exhaust.

For now, there’s just one spec of Poncams for the VR38DETT, but at 134,400 yen in Japan for the full set they’re priced competitively. You can also opt for just the in or ex set for 67,200 yen a pop.

Tomei have a big showing planned for Tokyo AutoSalon 2010 which begins later this month (15th – 17th Jan) so we’ll be sure to snap a few photos of the cams in the flesh.

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…

Well 2010 is about upon us so it’s time to roll out new noise regulations across Japan. The first aftermarket titanium exhaust we’ve seen that’s certified to the new standard is the Midori Silent High Power NR Titanium system proving it’s not all bad news for GT-R owners over there.

The Midori exhaust system is a mid-pipe back system that offers improved exhaust flow efficiency while keeping the loudness in check. In fact at full throttle it’s just 0.6db louder than a standard exhaust. At idle howerver it sounds more grumbly and bassy which at lot of us will appreciate and seek in an aftermarket exhaust.

Due to use of lightweight materials, the muffler section weighs in at just 8.65kg, a saving of 1.2kg over the standard OEM item.

COBB Tuning have completed yet another addition to their lineup just days after announcing their Intake Hose Kit for the GT-R. This time it’s a range of 3.5″ stainless steel midpipes for the GT-R which are built to the typical top quality finish of other COBB Tuning products.

The midpipes are constructed from 304 grade stainless steel and are tig welded and the flex sections are internally lined for extra durability. The primary pipe diameter is 2x 3″ which feeds into a single 3.5″ pipe downstream.

The catless version predictably deletes the two secondary catalytic converters on the OEM version while the catted version features two fixed high flow cat coverters to keep the exhaust nice and street legal.

The guys at COBB have seen some decent gains from this midpipe and have published the dyno charts using this really cool online dyno graph tool.

Head on over to the link below to check out just how much extra power they can squeeze out from just this simple to bolt up part…
