2017 is the year to push even further and we are now using the car to see how far we can go with the FA20 engine and Ecutek ecu.
Early 2017 we spent a lot of development time with the electronics systems, working hard on engine setup and integrating both the Aquamist ecu and Geartronics ecu to work with the Ecutek engine ecu.
The Aquamist system controls the water methanol injection, injecting the correct amount to match the fuel delivery, the system adds ignition timing and subtracts fuel from the injectors to keep a stable AFR. It is also failsafe so if water stops flowing the ecu reverts to the base maps.
The Geartronics ecu controls the gearchange in closed loop using a "load cell" on the gear lever to measure the start of shift and a rotary position sensor to measure when the shift is complete, the ecu outputs a signal that we can import in to custom maps to allow the gearchange in a super fast 0.12 second.
Engine development included a new version 10 of our software along with in gear boost mapping and a stiffer actuator, we have been able to maximise traction (as far as possible).
1st - 0.8 bar, 2nd - 1.2 bar, 3rd - 1.6 bar, 4th gear upwards - 1.8 bar
Also new this year is the 2017 model "Red Intake Manifold" and the Grams 72mm throttle body

1st October - Toyota Sprint - Cadwell Park
After a good learning curve in 2015 the team's knowledge of tuning the GT86 continues to grow and the winter of 15/16 was spent designing new product to make the car much quicker in 2016.
The first problem was fuel supply and we wanted to keep the original fuel tank so our "road" customers could follow us and get their cars up to similar power levels.
We replaced the standard fuel bucket assembly with Avo's high capacity unit which allows much more fuel volume around the 265 litre per hour uprated fuel pump. From the pump we are now using -8AN stainless braided fuel lines, splitting symmetrically under the intake manifold to -6AN and then feeding the standard fuel rails which have been modified with -6AN fittings. Also the direct injection feed has been 'T'd off the -8 line.
Back in 2015 we had reached the limits of the Avo stage 4 turbocharger and with our new fuel system we could safely push the limits further. Working closely with Avo Turboworld certainly has its perks and we were the 1st to use the new Avo Stage 5 ball bearing turbo! Based on a garret GT30 and with a larger exhaust housing it has improved exhaust gas flow needed for higher flow. Now the engine is running at 1.5 bar to the 7,800 rpm limit.
As the turbo is much larger the pipework has been custom made to suit and is of larger diameter to increase air flow.
Also new for 2016 is the Toyo 888R tyres which will certainly be well tested!
And what a year 2016 turned out to be, with 6 races and 6 overall wins and 1st overall in the Toyota Sprint Series :)
The end of the season is a perfect chance to get the GT86R on the dyno and we recorded 514bhp :)
Round 1 - Blyton Park
Round 4 - Anglesey
Round 6 - Snetterton
2015 has already been a busy year with work starting back in January working alongside Cosworth to help develop the FA20 engine. We now have a fully built forged engine with prototype pistons, con rods, headgaskets, ARP bolts and uprated valve springs. Testing will continue throughout the year ahead of public release.
The engine was "run in" in the snow in February and has now completed 1,400 miles. 600 run in and 800 race / test miles.
Also new for 2015 is the stage 4 Avo turbo kit with larger compressor and turbine wheels, carbon airbox, larger intercooler and 770cc fuel injectors. Our power target is around 500bhp.
The gearbox has now also been upgraded to cope with the extra torque and an Xtreme 230mm twin plate clutch is used.
Changes for 2015 include:
Cosworth forged pistons 9.5:1 compression ratio
Cosworth forged steel connecting rods
Cosworth multi layer steel headgaskets
ARP - Complete engine bolt kit
Kelford uprated valve springs
Avo Stage 4 Turbo
Avo Carbon Airbox
770cc Fuel Injectors
Samsonas 6 speed sequential
Xtreme Clutch 230mm twin plate
8-11th January - Autosport International

29th March - RRG Toyota Sprint Round 1
Round 1 of the RRG Toyota Sprint was held at Snetterton Race Circuit and was a complete disaster for us! Rain like you wouldn't believe and a virtually flooded track was not the debut we wanted. Grip was non existant, we only had "dry" tyres so boost was turned right down and Adrian managed (just) to bring the car home in 6th place.
26th April - RRG Toyota Sprint Round 2
After the disaster of round 1 the team were eager to get out on a dry track and Blyton didn't dissapoint! With dry weather and good grip the GT86R was ready to go. The 1st 2 runs showed a fuel surge issue which was quickly fixed and despite a boost control problem limiting power to 420bhp the car was stunning, leading from run 3 and finishing over 3 seconds ahead of the field.
A very happy Adrian!

Next job for the team was to install the fabulous Samsonas 6 speed sequential gearbox. The gearbox comes with an adapter plate and the correct spline so is a relatively easy install. We had to remove the standard gearbox mounting bridge from the tunnel and manufacture some new mounts along with a new propshaft to suit. Also the exhaust has to be re made to clear the larger gearbox. The gearbox is rated at 1000Nm of torque, far more than our rear tyres can handle!
And the finshed result can be seen here in our "in car" video, where the GT86R claims 1st overall on round 3 of the Toyota Sprint Series at Woodbridge.
Adrian says "This car is really coming together now and is just fantastic to drive, Woodbridge is one of my favourite tracks due to its "rally style" course with lots of surface changes, which makes for a great challenge. The new gearbox is just fantastic, the gear selection is light but positive and has really helped me get the best out of the car"
16th Aug 2015, Round 4, TSS, Croft Race Circuit
The team took the long trip north to the fabulous Croft Circuit, a favourite track among the drivers, the circuit is used by the BTCC and is super fast and challenging. Adrian says "I've often struggled at Croft and this time round I really wanted to try and get to grips with the high speed corners and finally get a win at this famous track"
He needn't have worried the race day was fine and dry and the GT86R was just fantastic other than an overboost problem on the 1st run and a driver problem on run 3 (forgot traction off button!) the GT86R performed faultlessly all day pumping in fastest times to claim 1st overall :)
Here is an "in car video" of the fastest run of the day :)
30/08/15 - Javelin Sprint at Cadwell Park
A one off extra event and an ideal test / practise session ahead of the final round of the Toyota Sprint Championship, we headed to Cadwell Park for the first ever time to learn the track and compete with some different cars. Adrian quickly got the hang of the track and was soon pumping in competitive times, 2nd overall by lunchtime he continued to improve his times, setting a 1:29.01 on the final run, still 2nd overall but to a Radical which was in a different class.
and in car video on Adrian's fastest lap
27/09/15, Round 5, TSS, Blyton Park Eastern Circuit
A great event at Blyton saw our GT86R come home in 2nd overall, a mere 6 hundredths of a second from the no 1 spot which went to John Crabtree in his Celica GT4.
07/11/15, Round 6, TSS, Cadwell Park.
The final! and what a showdown, it was very wet and this time we were ready, with a new spec lsd and wet weather Toyo proxes tyres the GT86R was transformed and Adrian could attack the track despite the challenging conditions, by lunchtime he had a healthy lead of nearly 3s but as it started to dry, the powerful GT4's were catching. Andy Bunney was quickest of them but Adrian managed to hold on to take the win by 0.48 of a second!
What a season, we count our best 5 scores and for the GT86R that was 4 outright wins and a 2nd giving Adrian the overall title!
Here's an in car video of a challenging Cadwell Park :)
Adrian reports -
"Wow what a year, the racing has been so much closer this year, making this championship win, one to remember!
We started off the season at Snetterton very poorly with a 6th overall in appalling wet conditions, we were caught out and had the wrong (dry) tyres. From round 2 on we have been very competitive securing 4 overall wins and a 2nd place.
But the event to remember was Cadwell park the final round, it was another very wet day and very challenging! We had the correct (wet) tyres this time around and a more progressive LSD making the car much more controllable in the slippery conditions. I was able to attack the track as I would in the dry and take the overall win, beating even the 4wd cars!
I can't thank the whole team at Fensport, all our supporters and sponsors enough for helping to build / provide such a fantastic car"
After finishing 2nd overall in the Toyota Sprint Series last year, Team Fensport have been very busy over the winter "off season". The aim was always to make the car significantly faster at the end of each year so changes for the 2014 season had to include more grip before more power!!
First and most obvious is the fabulous Blitz Aerospeed wide arch kit as used on the Blitz Racing project Time Attack car and also Ken Nomura's Blitz Drift car in Japan. The kit was shipped over and we were so pleased with the perfect fit straight from the box!
The Blitz kit allows for an 120mm track width on the rear and 110mm on the front. The arches have been cut out to provide more space for the new Rota 18 x 9.5" wheels which are clad in 265 wide Toyo R888's all round. Additional aero parts include custom front and rear canards, TRD aero fins, a higher rear wing and custom rear diffuser.
With the new found grip the team have also increased spring rates on the BC Racing external resevoir coilovers.
Also upgraded is the Avo turbocharger to the billet version which offers the same incredible response alongside a 20% increase in airflow.
The car has also been re mapped using Ecutek software to get the most out of the 108 ron race fuel, along with electronic "in gear" boost control which helps with traction in the lower gears.
An M Factory Carbon propshaft has been fitted to reduce rotational mass.

26/04/14 Pre season test at Blyton Park
We headed off for their first test of the season just 1 day before the first round of the 2014 Toyota Sprint and GT86 Trophy series. Testing went fantastic with only shock absorbers, ride height and tyre pressures being adjusted in time for the 1st event.
27/04/14 Round 1 Toyota Sprint Series
We couldn't of asked for a better start to the new season, after just 1 run, Adrian was reporting back and saying the car had incredible grip, great power and perfect balance.
This car deserves a kiss!!! The car ran faultless and went on to win on it's debut.
As the summer has progressed so has our modifications, and after a broken driveshaft on round 2 we invested in some heavy duty shafts, since then we haven't had any problems since.
TRD heavy duty engine and gearbox mounts are now installed to cope with the increased engine torque. A RacerX alloy sump whish is baffled internally and also increases oil capacity has been installed along with a low temp thermostat.
Then it was time to find out how are engine tuning was developing, so we headed off to Ecutek for a power run on their dyno, and here is the result :)
We have had a fantastic year with our GT86R, finishing 1st overall at 5 rounds of the Toyota Sprint Series and securing the overall championship :) Other than a broken driveshaft, the car has run fault free all year and we are so looking forward to 2015!
2015 will see some further changes, it's always our plan to keep developing the 86 platform, so stay tuned for 2015 updates :)
A huge thank you to all our supporters and sponsors, for their support, and for making it all possible :)
January: A new year and lots to do!! We are continuing to develop the GT86R in preparation for this years Toyota Sprint Series.
Roll cage installation, a full FIA International Spec multipoint cage by Custom Cages has been installed
The roll cage and interior were finished in time for the car to be on display at the Autosport International on the Summit Racing stand along with new Summit adjustable rear suspension arms, strutbrace and underbracing:)
Next modification is the Turbocharger!! Our preferred choice is the Avo Turboworld kit and we're pleased to announce Fensport as the European distributor for Avo, we will be working closely with them and developing the kits for EU spec cars and conditions.
We are using the Ecutek software to control boost electronically, the Race Rom maps have allowed us to control boost in gear , against throttle as well as have a full 'closed loop' system. A 3 bar map sensor has also been added along with an overboost fuel cut. Boost is set to 0.5bar.
Another addition for this season is a M Factory 4.44 final drive along with a 1.5way plate lsd, both will help the rear differential get all the extra power to the ground!
Also changed this year is the front brakes, which has helped to save rotaional and unsprung weight, we have opted for the excellent Stoptech 4 pot front calipers with a 328mm discs.
Another area we are always improving is weight reduction, so a full perspex window kit has been fitted including side and rear windows. The doors are lightened now the roll cage is installed, the rear parcel shelf has been trimmed down.
The car has been prepared for the 2013 Toyota Sprint Series, now running in Pro Tuner class and up against some very powerful 4wd opposition.
The 1st round of the Toyota Sprint Series held at Blyton Park Circuit saw the Fensport GT86 claim 1st in class and 5th Overall.
The team suffered brake problems on the day, earlier in the week the decision was taken to disable the abs system and it cost the team dearly with front brake lock up! Lesson learned don't disconnect the abs!! Despite the brake problem the team were very happy with the car's handling and balance. The power is fantastic and now the brakes are fixed we are really looking forward to Round 2 at Woodbridge on the 19th May where we plan on getting that perfect run!
10 - 18th May
After the first round the power has been increased, boost is now up to 0.75 bar with more mapping and high octane race fuel. A full 3" Blitz prototype exhaust has been manuufactured in house from the turbo to the back bumper. Power is now approx 320bhp.
Back out on track, this time at Woodbridge a nice open long track we needed the extra power to keep up with the 4wd cars, and the GT86 didn't dissapoint with 2nd palce overall :)
21st May - 8th June
After our second place we were pleased but know we have to push harder, we are after a win this season and a good overall result in the championship.
The next round of modifications begins ....
A stiffer actuator has been fitted to increase boost response, boost is left at 0.75 bar but the new actuator helps the spool up time in the lower gears. Wider 245 section Toyo R888 tires are fitted to help with traction and put the power down. A new lighter intercooler and alloy front bumper bar reduces front end weight.
And new Seibon carbon front splitter and an extra pair of canards help to generate more front downforce. Also fitted is a Seibon rear boot lid to help reduce more weight.
Toyota Sprint Series Round 3, held at Barkston on a purpose built tight and twisty sprint track. We finished 2nd overall and closed the gap to the more powerful 4wd cars, missing the win by just 0.28 of a second.
Next job was to get the car on the dyno and test our power modifications were heading in the right direction, 334.9bhp and 266 ft-lbs with beautiful smooth power and torque curves :)
Also fitted now is the beautiful carbon fibre bonnet from Seibon, as well as adding extra cooling for the engine bay, it also weighs 1.2kgs lighter than the standard bonnet.
Huge thanks to Autocar and Toyota GB for hiring Bedford Autodrome and producing a stunning video of both our street and race GT86's going up against a standard GT86 and also a Mclaren MP4-12C for comparison. We had a fantastic day and the GT86R emerged as the victor :) :)
Fensport GT86R vs Mclaren MP4-12C - Autocar review of the Fensport GT86 turbo cars
Our GT86 Racing Project is well under way, read on to see how we have modified our GT86 from a standard road car to a turbo charged race car ....
Toyota GB supplied the car to us on the 12th July 2012, we are working with Autocar magazine who will cover the story in a series of features starting with the standard car and following its progress and modifications to compete within the Toyota Sprint Series.
Autocar's Steve Sutcliffe will join Fensport's Adrian Smith as the lucky drivers who will be the first to race the GT86 in the UK :) The pair will be competing on the last 3 rounds of the Toyota sprint series in preparation for a full championship assault in 2013.
Diary - Planned modifications and timescales 2012
12th July 2012
GT86 Delivery :)
Car on display at Marshalls Toyota Peterborough, GT86 Launch and Open Day
16th July - Development Commences
The first steps to modifying the new car was to measure all the suspension and understand how it all works, a BC Racing coilover kit was installed without springs so we could measure bump steer, toe & camber change etc and get a real understanding of how the suspension works. This is very important to learn on a brand new car so later we can alter the handling to suit.
Whilst working on the suspension it was soon very apparent that there is a lot of tension within the standard rubber bushes. As well as having no adjustable camber on the car. These were areas we wanted to improve.
Next step was to install different offset wheels to attain the correct fitment with the widest possible track without fowling the arches.
Parts fitted so far
BC Racing Coilover kit 5kg front and 5kg rear springs, 32 way adjustable.
SuperPro polyurethane bush kit (releases the tension in the suspension arms, whilst keeping correct location)
Racecar Battery, an amazing 1.6kgs, has saved nearly 12kgs off the front of the car.
Ultralite Atec wheels (painted pearl white) 8 x 17 ET35 perfect fitment and the correct size for our tyres.
Toyo R888 GGG tyres 225/45/17
Carbon mirrors and rear wing
Blitz panel filter and high pressure radiator cap
Camber adjustable rear arms
Remove interior trim, stereo and airbags, replace steering wheel with a Momo suede wheel, we have still kept the steering angle sensor so all traction and stability controls work as standard. Install Recaro race seat. Trim around the driver has to stay at the moment until a roll cage is fitted.
Corner weight and wheel alignment
Weight is down to 1120kgs with 1/2 tank of fuel :)
12th August - 1st event - Toyota Sprint Series
Fensport GT86 stuns the competition and takes 1st overall in it's very 1st event :)
To be the 1st to race the GT86 in the UK was a very proud moment for both Steve & Adrian, Adrian was 1st up and immediately set the pace, Steve only a few tenths behind. Both drivers were amazed by the sheer pace of the car, the corner speed was immense and both continued to push as hard as possible. The new handling characteristics were very obvious both inside and out of the car.
Both drivers were also driving a standard GT86 to compare the differences between them. The Fensport GT86 was an astonishing 4 seconds quicker over 3/4 of a mile track proving the modifications have made a substantial difference!
The final result was Adrian winning 1st overall, and Steve taking 3rd overall :) What a debut for the Fensport GT86, it has now earned it's new name Fensport GT86R :)
Read more Fensport GT86R First Britsh Win
Modifications resume and the Fensport team have certainly been very busy!
In preparation for the next round of the Toyota Sprint Series, the Fensport GT86 has undergone another massive transformation including....
K Sport Front 8 piston, 330mm brake kit.
Prototype Blitz Nur Spec single exit exhaust (7kg lighter than std system)
Rear aero underneath to reduce drag
Whiteline heavy duty front and adjustable rear anti roll bars
BC Racing external resorvoir coilovers with seperate bump and rebound damping, 6kg rear springs and 5kg front springs.
Samco intake and radiator hoses
Helix uprated 4 paddle clutch and lightweight flywheel, clutch clamping force has been increased from 540kg to 1000kg. The standard clutch was always a weak link when racing!
Corner weighting has revealed the new weight of 1090kgs with 1/4 tank of fuel :)
Front Canards have been added to increase downforce in the higher speed corners.
Toyota Sprint Series, Round 4, Croft Circuit
A fantastic result at Croft Circuit for our GT86R, 1st in class and 3rd overall against some stiff opposition with much more power :) Adrian's fastest time was 92.76 just 1.1 seconds off of 1st place. The car was also driven by Matt Saunders from Autocar and Matt put in a very creditable drive to 4th overall with a 95.59s. Both drivers also drove a standard GT86 in the 'Street Class' Adrian finishing 9th overall. The Fensport GT86 proved its modifications once again by being 6.8 seconds faster than the standard car over just 1.7 miles :)
Thank you to Brian for the on track pictures :) Motorsport photography at Saidro.com
Modifications resume in preparation for round 5 of the Toyota Sprint Series
Fensport lightweight crank pulley, Fensport oversize alternator to reduce alternator speed, and Fensport oversize water pump pulley to reduce water pump speed. All the pulleys together save nearly 2kgs off the rotational mass.
Lightweight Carbon propshaft saves 4.65kgs off the rotational mass.
Ecutek ecu mapping - Fensport are now an authorised Ecutek tuner for the GT86 and BRZ, the first maps have been done and showing 218bhp and 171 lb/ft torque :) Our modifications listed above and our mapping using the Ecutek software has gained approx 25 bhp and nearly 20 ft/lbs , nicely extending the torque and power curves
Also added is the fantastic Race Rom features which provide Full Throttle Shift, Launch Control and Auto Blip on downshift.
Toyota Sprint Series, Round 5, Snetterton circuit
After our last round of modifications, new power output and lighter weight we were looking forward to the final round of the Toyota Sprint Series. Using 1 and 3/4 laps of the new "100 circuit" we knew it would be tough to keep up with the more powerful turbo and 4wd cars!!
The morning started very wet and damp which is not so good for us, the key to quick lap times in a GT86 is corner speed, and with the slippery conditions we were some way off the 4wd turbo cars, however it started to dry and by lunchtime Adrian was leading the class and managed to sneak up to 2nd overall, before being knocked back to 3rd by Jonny Milner in his MR2 Turbo. Matt Saunders from Autocar Magazine was also driving the car and was getting progressively quicker. By run 7 and with fully dry conditions it was Adrian in 3rd and Matt in 4th, with 1 run to go, both GT86 drivers pushed the car and driver limits, both improving their times and Adrian snatching 2nd overall Jonny and Matt 4th. A fantastic result considering the much more powerful opposition.
3rd & 4th November
After the show the car will be stripped and modified further in preparation of a full championship in next years Toyota Sprint Series.....
What a fantastic start to our 1st year with the GT86, After competing in only 3 rounds we have finished an impressive 1st at Barkston Heath, 2nd at Snetterton and 3rd at Croft, against a wave of 4wd turbo competitors. In the last race at Snetterton we finished a mere 0.44 seconds behind a 400 BHP Celica GT4.
We have absolutely fallen for the GT86, a fabulous car even in standard form, the Fensport car is now on a another level, handling is sublime and almost a game changer, the low centre of gravity coupled with wide track and our suspension modifications have produced a simply stunning car to drive. All of our modifications have been documented above and we have done our best to keep the car real, just sensibly priced bolt on parts have been used and we feel that the future for the GT86 is very bright indeed :)
We are very much looking forward to the winter break so we can continue our GT86 development programe which is expanding at an incredible rate, with many parts for both road and race cars in the pipeline, be sure to check back soon.
We would like to thank the following sponsors, for their support, and for making it all possible :)
