Akuma GTR Big MAF(BM) Intakes. The right mods for the most power.

admin — Thu, 02 Sep 2010 14:41:02 +0000

We have spent countless hours working with the new R35 GTR. From the early days working at Cobb, until now, this car has been a staple in the Akuma Motorsports vocabulary. We have put our usual attention to detail in these intakes and they have proven to work flawlessly. Unlike many intakes on the market, the AKUMA BM Intake tunes very easily. It retains consistent MAF values throughout the MAF curve. Goodbye to P0700 codes from the other intakes your tuner may have worked with. These intakes walk the walk and talk the talk. AVAILABLE IN POLISED SILVER OR GLOSS BLACK.

CONSTRUCTED FROM 6061 ALUMINUM
SEAMLESS ONE PIECE Construction, NO WELDS in the intake tract!!!
SUPERIOR FLOW: BM is the solution for the guys running more than 17PSI on STG or STG2+ cars. Makes tuning big injectors a breeze!
K&N Hi FLOW CONE Filters **INCLUDED**
NEW SILICONE REDUCERS(2 per kit) TO REMOVE THE OLD ACCORDION PIECES FROM THE FACTORY
**All the necessary clamps are provided in both kits for a drop in installation with a screwdriver and a 10mm socket NO NEED TO REMOVE THE BUMPER!**

We are coming up on our 1 year anniversary and we have been busy. I know we have been away from the blog for a bit, but we have good reasons for that absence. We have been so unbelievably busy with customer build and our 2 shop cars. This is our 2008 STI. The idea is to have a Street Class car that is still registered and emissions compliant, and have that car be a class leading contender.

Here are the updated details and some pics. We fabbed up the new radiator shroud and Aluminum firewall, this week to eliminate the rear seat which was a porky 39 LBS!! I will update this as we go.

Akuma Motorsports presents the public with a project we’ve been looking forward to. We will be swapping a Rb26DETT motor into this 1975 Datsun 260z. As the build goes on, we will keep an update but the car got dropped off today. We will be taking apart this old school ride, so keep it locked here for pics!!

Cheers!

What a nice day!

Akuma Motorsports decided to throw a meet this past Saturday, 11/28/2009, to take advantage of the great weather we had here. It was 12:30 pm, Evan (our fabricator/tech) came up with the idea of throwing a spontaneous so we decided to post it up on all the forums we were part of. Although the meet was small and last minute, some of our closest friends/customers still decided to drop by. This meet was more of a “hey come hang out” kinda of thing, while John,Evan, and Doug kept on wrenching on Akuma’s Shop STI. Which by the way, gave its first roar with the new motor in it. These pictures were taken by our good friend Pete so I wanted to thank him personally for that. Stay tuned for more details about our “Pre-Christmas” Cruise/Meet. Enjoy!

Look at what we found!

As we disassemble the motor on our Mazdaspeed 3 build, we are also looking for signs why the engine popped. After a took a closer look at everything we have found a MAJOR issue with the intake valves. All of them was covered in what looks to be sludge. I apologize in advance for poor picture, as it was difficult to get proper lighting inside the head. Take a look!

A bit of Mazda at Akuma Motorsports.

Akuma Motorsports serve a variety of vehicles such as Nissan, Subie, Mitsu, and anything you can throw at us. We deal with a good amount of Mazda Speeds here as well. This is a teaser shot of our full engine build for one of our customers. There aren’t many Mazda Speeds out there compared to the Subies and Evos, so to have one here for us to full build is very exciting. The vehicle is getting Carrillo Rods and CP pistons, more info about the vehicle will be released as the build moves forward. Make sure to check back here for updates!

Cheers!

Keepin it cool!

Look what the mother land brought us today! Its so JDM that the newpaper packaging is in Japanese. What we have here is the HKS Kansai Transmission Oil Cooler for the R35 GT-R. For our serious track junkies out there, this is a must for your Godzilla. As you can see in the pictures, it comes with a fiberglass duct to direct air directly to the cooler, all the accessories you need to mount the kit, and the cooler itself. The kit mounts on the driver side front bumper right by the washer fluid reservior. This kit screams engineering but it doesn’t surprise us since it does come from HKS Kansai. Under hard driving laps after laps on the track, The R35 GT-R’s transmission oil temperature will be overheating and causing the car goes into limp mode. HKS Kansai notices the problem and develop their own transmission oil cooler kit.

More Goodies Have Arrived!!

As I walked into work Today, the first thing I see are these four GREEN looking stick things. I paused for a second and it finally clicked to me, these are the brand new Tein Super Street Circuit Masters Ultimate spec coilovers with Dual EDFCs. Not are these only adjustable on the fly in-cabin for compression, they can also be adjusted for rebound. For those who are afraid to loose the functions of eletronic dampening these are the coilovers for you. On the EDFC control box, you can have 3 different damper settings for different driving conditions.

TEIN Super Racing (SRC) coilovers feature Teflon coated mono-tube constructed dampers in a full length adjustable design allowing for adjustment to ride height separate from suspension stroke. The SRC design utilizes external reservoirs both front and rear allowing for independent damping force adjustment to compression and rebound. Pillowball uppermounts are also incorporated for added suspension response by eliminating deflection at the uppermount.

Another pretty piece that came in are the Forge Actuators. These are nothing short of spectacular from functionality and looks. These actuators will benefit boost taper up top compared to the stock pieces, control boost better, and also a nice looking piece to put in your engine bay. GTR Actuators from Forge Motorsports are adjustable and come with three different springs: 10-15psi, 14-18psi, and 19-24psi. Like all turbo setups, getting the correct spring for your wastegate is critical. An improperly setup wastegate will cause boost lag or creep and reduce the performance of your GT-R.

Our Endless Brake Pads have come in as well. These pads are top notch and should make our GT-R very capable for both street and track use. These not only offer an increased performance in stopping but also provided excellent inital bite. Check them out!
