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.


Our Time Attack GT-R is official!

18 Mar{ 0 }

Here it is! Our competitor for this years Time Attack series in Sweden! It´s a GT-R with a GT3 carbon body kit from Nismo. The car will have the AWD system from the street car, in modified form. The engine will have around 1000hp and a modified gearbox to cope with it. We´ve gotten ourselves a pro driver that will drive the car. It´s Alx Danielsson, who´s one of Sweden´s most successful drivers of all time. The first race is at Kinnekulle Ring 22-23 of May. A lot more info will be posted during the season. In the meantime enjoy the below pictures of the car. And if you feel the urge to have your own GT3 GT-R built, just get in touch and we´ll make your dreams come true!









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.


Busy busy

Even though it´s still winter here in Sweden, we´re very busy as you can see in the pic below. If you want some work done to your car, please get in touch now to book a time, since our calender is filling up quickly.


The second Syvecs equipped car is a Spec V!

8 Feb{ 0 }

This rare and unique Spec V is the only one in Sweden. It´s a very low mileage car in excellent condition. Its owner wanted some more power so he choose more or less the same upgrades as we did on the first Syvecs build:

Syvecs ECU with Flex Fuel sensor
GTC Intake pipes with K&N filters
GTC Downpipes
ASNU 1100cc injectors
AMS fuel rails with regulator
Both fuel pumps upgraded

Since the Spec V have larger turbos from the factory, this car got more power compared with the first one. The peak numbers are 541awhp/681awNm. Both numbers are corrected. Here are some pics of the dyno sheet, the car itself and the amazing titanium exhaust Nissan made for it. If you want some more power in your GT-R, drop us a mail and we´ll take care of your car.

The first Syvecs equipped car is done

6 Feb{ 0 }

Here´s the dyno sheet and a pic of the first Syvecs equipped car we´ve built. It was running a COBB Accessport before, but now it´s in a different league of engine control and protection. It´s also running Flex Fuel so the owner can fill it up with either E85 or 98 octane or a mix. The numbers in the dyno sheet are corrected and the peak values are 522awhp/684awNm. This is on the Mustang dyno we always use. The mods on this car are:

Syvecs ECU with Flex Fuel sensor
GTC Downpipes
GTC Intake pipes with K&N air filters
GTC 4″ midpipe and catback exhaust
GTC Intercooler
ASNU 1100cc injectors
AMS fuel rails with regulator
Both fuel pumps upgraded

If you want some more power in your car, just get in touch!

Syvecs ECU in stock

29 Oct{ 0 }

Here´s a picture of the two Syvecs GT-R ECUs we just got in stock. As we´ve posted before, Syvecs are powering all the fastest GT-R builds around the world so we know they can make tons of power. The other outstanding feature the Syvecs ECU offers is the protection of the engine. It has a number of built in safety features that other ECUs simply don´t have. It´ll be very interesting to see what results we can get from them. Stay tuned for more info.

Syvecs S8 – the best ECU a GT-R can get

18 Apr{ 0 }

We are proud to introduce the most advanced engine control system available for the GT-R – Syvecs S8. Here are some of the details from the press release of the ECU and also a Youtube clip that show what can be done with it. Basically you can do anything you want with it. If you´re interested in getting one for your car, drop us a mail.

SYVECS Ltd, producers of Advanced Engine Management Solutions in the UK, are
proud to announce the release of the S8 R35GTR Kit

– The world’s first stand-alone Engine Management Solution for the Nissan R35GTR
Over the last 12 months SYVECS has been working hard to develop a completely new
product for the tuning of the Nissan R35GTR.

Around the world, as the limits of the VR38DETT are pushed further and further, the
last hurdle to jump has always been the OEM ECU. Now free of the restrictions that
re-flashing of the stock ECU imposes, tuners can now use the SYVECS EMS to go
further, push harder and take advantage of the superior control, Motorsport
developed strategies and full data logging that it offers.

The advanced engine management, together with a full software suite, offers
unbeatable flexibility and protection to all tuning levels, safeguarding your
investment, while maximising performance.

The SYVECS S8 R35GTR kit is a stand-alone unit enabling the complete removal of the

The new unit enables live adjustment of every aspect of the engine’s calibration,
while also offering the ability to control the TCM Module for adjustment of gear shift
points, clutch clamping pressures, torque reduction, and much, much more!
Browse through the feature list, and contact SYVECS to learn how the S8 R35GTR kit
can push your vehicle to new levels of performance.
