Throw Back Thursday

1 Dec{ 0 }

Today we give you a look at some of the Nismo GT-R´s we´ve worked on. There are five of them in Sweden and we´ve worked on three of them. One got a gearbox cooler, one have been tuned (the first Nismo in Europe with an Cobb Accessport) and one got a half cage and a race harness installed. Hope you like the pictures!

If you want some work done to your GT-R, please let us know what we can help you with.

After a summer with too much work, we´re back with the most powerful car that´s been on the roller´s of AG:s i Norrköping´s dyno! The new record numbers are 1139.8 whp and 1011.4Nm! A huge thanks to our customer and also to Tony at AG:s who made a great job with the mapping as usual!

To give you an idea of what numbers we usually see on this dyno, a Full Bolt On GT-R on E85 puts out between 550 and 570whp.
If you want to have more power in your GT-R, get in touch and we´ll help you achieve your goals.


KW Sleeve kit

2 May{ 0 }

The owner of this GT-R likes to keep his car tidy and he also want just the right look of the car. Therefore we installed a KW Sleeve kit to get is just right. The second picture is one the owner posted on IG when he installed the new wheels later the same day.

Transmission cooler

1 May{ 0 }

This low mileage 2010 GT-R was in the shop to get ready for the track season. It´s an old customer of ours that owns it and we´ve done a lot of work on the car before. This time we installed a South Side Performance transmission cooler and did the yearly maintenance. It´s one of the nicest and most well kept GT-R´s we´ve seen.

Another FBO GT-R ready

29 Apr{ 0 }

Another FBO (Full Bolt On) GT-R with Flex Fuel is ready for delivery. This have become more or less the default choice for our customers that wants a fast car for reasonable money. The E85 gives another 40-50 awhp on top of the 500-520 that the 98 octane delivers. The results for this car were 526awhp/639awNm on 98 octane and 568awhp/723awNm on E85. We also did a Stage 1 upgrade on the gearbox on this car.

The brake cailpers for our Time Attack GT-R have arrived. It´s a set of Brembo GT calipers. They weigh 40% less than the OEM calipers. This is pure fabrication porn so maybe we should label it NSFW? Thanks goes to Brembo and LM Motorsports for supplying them.

Gearbox problem solved

This nice blue GT-R came into the shop with a gearbox problem. We solved it and now it´s ready to be delivered.
Send us an email if you want to upgrade your gearbox to avoid problems.


Rear subframe better than new

19 Feb{ 0 }

This week we´ve finished another renovation of a rear subframe. It was really rusty so we removed it, sand blasted it and got it painted. After that we installed new nuts and bolts, new swaybar links and protected everything with anti rust spray. Hopefully the owner will have at least another 80000km to drive before he even needs to think about this problem again. Most likely, he´ll never have to worry about it.

More carbon parts arrived

6 Nov{ 0 }

Last week we got the next shipment of parts for our Time Attack project. Below is a sneak peak at the front fenders, which are a lot wider than the OEM ones. It almost looks like it´s installed in the wrong position, but it´s not. It really is THAT much wider. Stay tuned for more parts we´ll show you later on.

Another silver GT-R in for a service

21 Sep{ 0 }

This is the 113th GT-R we´ve worked on. It was in for a service and we were happily surprised to find that it looked like new even though it´s over 5 years old. It´s only covered less than 14000km and it´s never driven in the rain, and it shows. It looked great! Get in touch if you want to book a service for your GT-R.


Mr K. is back for a service before going to the Ring

20 Sep{ 0 }

Mr K. is another of our long time customers. He uses his GT-R mostly on track so it needs a lot of service. This time we replaced all the fluids and did some work on the brakes. The front discs and the pads both front and rear was replaced as well as the brake fluid. The car is now ready for the next adventure to the Nurburgring. When Mr K. was at the workshop we couldn´t resist taking a picture of another blue GT-R with some nice aftermarket wheels on it. Mr K´s car is on the left. The car on the right will we show you more of later. If you want to know which wheels the cars have, it´s Volk Racing G2 on the left and Advan Racing GT Premium Edition on the right. Send us a mail if you want to book your GT-R in for a service or if you want a new set of wheels.


Silver GT-R in for a service

19 Sep{ 0 }

We did a service on this 2009 GT-R that´s only done 13000km. It´s nice to see some other colours beside black for a while. Call us if you want to book a service for your GT-R.


Next E85 tuned GT-R is ready

18 Sep{ 0 }

We recently finished this 2013 GT-R that got a Flex Fuel upgrade. The result was 553awhp and 671Nm on E85. We tested it back in January when it was stock. Then it had 425awhp. We also ran it earlier this summer when we upgraded it to Stage 2. Then it had 486awhp on 98 octane. If you think your GT-R need more power, just let us know and we´ll help you out.

The first modified 2014 GT-R in Sweden?

17 Sep{ 0 }

No, it´s our long time customer Mr S. that continues to modify his 2009 GT-R. We showed you before that we replaced the rear lights with the 2014 model. Now it was time to do the rest. And what a job it was! We didn´t only replace the headlights. Mr S. decided he wanted to do a full upgrade to the 2014 look, minus the wheels. So, we installed the following new DBA parts:

* Front bumper
* Front splitter
* Rear diffuser
* Lower rear bumper
* Engine room harness

This is probably the biggest “cosmetic” job we´ve done, since it was so much work to replace the engine room harness. Both we and Mr S. are very happy with the result though. If you like the new 2014 look and want us to upgrade your car as well, don´t hesitate to contact us.

Major gearbox headache

16 Sep{ 0 }

This car have caused the owner a lot of headache. He hadn´t seen the car for 6 months when he picked it up from us. The reason is that another shop were supposed to fix the gearbox when it failed, but they didn´t have the correct knowledge, tools or spare parts to do the job correctly.

We found a number of faults in the gearbox that we fixed. Here are a few:

* Only 3 of 21 bolts to the oil tray were standard. The reason was that they had damaged a lot of the threads and decided to use longer bolts instead of repairing the threads. We had to repair 10 of 21 threads.

* Both the o-rings for the heat exchanger and the gasket to the oil tray had sealant on them instead of using new parts when assembling the box.

* The pinion gear and output shaft for the FWD in the box were damaged. See pictures below. Instead of replacing them with new parts had someone tried to grind them!

* The magnets in the oil tray hadn´t been cleaned.

* One of the 5 bolts that hold the solenoid pack was completely loose.

* There was a lot of dirt in the box, even though it was supposed to be cleaned and overhauled.

Hopefully the car will work for a long time now.

More broken drivetrain parts

13 Sep{ 0 }

Here are some more parts that we´ve replaced the last few weeks. A broken front differential, upgrading a few gearboxes and also repairing some FWD clutch assemblies. We are the only ones in Scandinavia that are Dodson Pro Dealers, which means we have been trained by Dodson on the GT-R gearboxes. If you have some problem with your gearbox, make sure your car gets repaired by us.






Highest mileage GT-R in Sweden?

12 Sep{ 0 }

This car was back for another service. It´s probably the GT-R with the highest mileage in Sweden. This time it was in for a 90,000km service. It´s always nice to see the cars being used as Mizuno-san intended. If you want to book a service, let us know and we´ll help you out.


Service before the next Ring trip

The 108th GT-R we´ve worked on is a P800

10 Sep{ 0 }

This is the 108th GT-R we´ve worked on!! Thanks a lot to all our customers for your continued support!

What you see in the pic is the 4″ exhaust from GTC Racing Technology that we´ve installed. What you don´t see is the P800 package from Switzer Performance that´s also there. The transmission was upgraded with parts from Dodson Motorsport. It made 622awhp/712Nm at the dyno.

BMW 335 + COBB Accessport = happy customer

8 Sep{ 0 }

Here´s something we normally don´t work with. Tommi from Finland visited our shop with his nice BMW 335 to get a COBB Accessport installed. We managed to cut 3.2sec off his 100-200km/h time with the stage 1 map in the car. Not a bad result and Tommi was very happy. If you have a BMW or any other car that can run an Accessport, just get in touch and we´ll make your car faster, just like Tommi´s.


The dyno result for the most powerful GT-R in Scandinavia

12 Jun{ 0 }

This was the result. We were sniffing at 1100awhp but had to turn down the boost due to surge. We´ll be back on the dyno as soon as we´ve replaced the turbo inlet pipes to claim the dyno record which is 1099whp.


Scandinavias most powerful GT-R!

11 Jun{ 0 }

It´s been a long time coming but today we ran the 1000hp project on the dyno. The goal of 1100awhp was not reached, but it´s still Scandinavias most powerful GT-R by some margin. We´d like to thank our customer, Tony at AG:s and of course Ryan from Syvecs Ltd who mapped the car.

Boost was turned down for safety reasons so the car has more power in it when we make some changes to the setup. We´ll just leave this picture here and let you guess how much power it made. The video clip will be up in a day or two.


Time to reveal our new project

12 May{ 0 }

Since our Open House is over and we´ve shown our customers what we´ve been teasing you with the last few days, it´s time to reveal it here as well. The plan is to build a Time Attack GT-R which will be ready for the 2015 season. Therefore we´ve bought an almost complete body kit from a Nismo GT3 GT-R. The base car is a brand new 2012 GT-R which we´ve started disassembling. So, what do you think? Are we completely nuts or is it cool in just the right way?

Open House 2014

11 May{ 0 }

We want to say a huge thanks to everybody that visited our Open House yesterday! 17 GT-R´s were present during the day. In the picture there´s 15, but we had two that showed up late.

The 458 owner also has a GT-R but his son was driving it yesterday so he showed up in the “other” car.


The red GT-R is finished

8 May{ 0 }

Today we finished a customer car that we´ve been working on for some time. We upgraded the gearbox with our Stage 1 kit plus a stronger clutch basket and 1st gear kit. The engine was tuned with a COBB Accessport Flex Fuel map, downpipes, intake kit, injectors and fuel pumps. The car already had a Meisterschaft exhaust installed. We also installed a KW Sleeve kit to be able to lower the car. The result was 551awhp on E85 on the Mustang dyno today and a slightly lower car.

2014 tail lights installed

1 May{ 0 }

Today we replaced the rear lights on our customers 2009 GT-R with the new 2014 version. We also took some pictures that show what they look like when we have the GTC tail light kit installed which turns all four lights on at the same time. The final two pictures show difference between before and after we installed a GT-R Nismo gear knob in the same car. We can supply any Nissan or Nismo part you want for your car.

VR38DETT miniature model

24 Apr{ 0 }

This is something very special and at the same time also very Japanese. It shows the passion for the GT-R in Japan, that they even come up with the idea to produce something like this. It´s a miniature model of the GT-R engine, the VR38. It comes as a kit which you assemble bit by bit. You get each package when you buy the magazine and the packages you see below are 1-16 of 30. The production runs until August this year.

The model itself can not be bought, you need to buy the magazines to get the packages and build the model. The engine can be turned and the left side of it is cut up so you can see the pistons, cams and other parts moving when you turn it. Also, the stand for the engine has a button you can push that starts playing the engine sound.

You can see a clip of the complete model here:

As far as we know, this is the only model in Europe. If you´re interested in a VR38 model of your own, get in touch and we´ll arrange it for you.

The 1000bhp project is alive!

18 Apr{ 0 }

Last year we told you about the 1000bhp project we we´re building for a customer. During the course of the project it´s been upgraded and changed to a more extreme specification. Now the goal is 1100awhp! So, to achieve this we replaced the turbos to even bigger ones. And now the customer have picked the car up and is running in the engine. The pic you see below is just the spec for running in the engine and not the final one. The car will be back soon for an oil change and the last modifications before final engine tuning will be done. What do you think of the result so far? Not too bad, right?

New seats installed

16 Apr{ 0 }

Today we replaced the seats in a customers GT-R. He accidentally ripped a hole in the seat base of his drivers seat some time ago. Instead of fixing it, he decided he wanted a fresh set of seats. And since we had a nearly new set of Black Edition seats in stock, we installed them in his car. BTW, we don´t pass judgement on our customers taste in blankets. 🙂

This GT-R is probably the best maintained GT-R in Sweden. It´s in amazing condition and it´s also very low mileage. It came into our shop to get a Stage 1 gearbox upgrade, a service and some other small work done.

New brakes and a service

10 Apr{ 0 }
