This exciting project has a number of surprising elements, the power the car makes, just how fast and driveable the car is every day, the unusual but enjoyable VR6 engine sound and the age of our client who wanted this work done…he is a retired gentleman, let’s put it that way!
We were tasked with fitting a Rotrex supercharger to this Audi TT 3.2V6. There is no specific kit to fit this car so we custom designed and built the whole thing.
Take a look through the pictures further down to give you an idea what we did.
Next on the cards is a clutch upgrade for the DSG transmission.
This rare and wonderful Lotus Esprit 2.2 Turbo came to us with running issues, we have just given the car back to the owner in the last few days.
This fourth generation (Peter Stevens redesign) Lotus Esprit from 1989 features a 2.2l 4 cylinder turbo-charged engine. We have worked on this car before, fitting upgraded suspension components and various other modifications.
The engine unfortunately had a number of oil leaks when it was brought into us. It was running really rough and she clearly wasn’t well.
We diagnosed the oil leaks, injectors and plugs as being the factors.
We stripped the engine to enable us to reseal parts such as the sump gasket, crank seals, rocker cover gasket and oil pump gasket.
Wheile we had the engine out we also installed a new clutch, new cambelt and new water pump.
Please check out the pictures below
We gave the car a mini overhaul while it was with us, including suspension upgrades and body modifications.
The work we carried out included: upgrade rear splitter requiring modification to the stock bumper and re-colouring the reverse sensors, upgraded suspension springs, upgraded air intake system, upgrade exhaust by Miltek, bonnet lifters and chassis strengthening; all adding to the overall functionality, performance and style of this stunning car.
Take a look through the pictures to see what was done! thanks again Steeda UK for supplying all the top quality parts.
This Vauxhall Monaro VXR came in with a knocking bottom end, which is a rare situation with these ‘bullet-proof’ LS series Chevrolet engines. Never the less, we know this car has taken a beating and while the engine needs to be rebuilt, it would be rude not to carry out some upgrades too.
These include, forged rods, lightened and balanced bottom end, upgraded cams, upgrade valve springs, high flow inlet manifold, full exhaust system including manifolds and a K&N induction kit.
With all this work now complete we run the VXR up on our dyno where she produced 530bhp, with a very clean torque curve, developing power all the way.
This 997 Porsche 911 C2S came to us as it had a number of different noises coming from the engine bay, plus there was smoke coming from the exhaust.
We could see straight away the engine was burning oil, the smoke from the exhaust was the giveaway.
We know there is a common issue with nickel cylinder liners on the 3.8 litre engine as we have rebuilt so many of these engines now. But we perform a full diagnostic to be sure of the root-cause.
We used a bore scope to inspect the cylinder liners and pistons. We found 2 cyclinders on bank 2 which had pick-up, this is where the piston starts to wear away at the cylinder wall and this in turn causes oil to get into the combustion chamber (above the piston).
We stripped down the engine to confirm the fault.
The remedy for this fault is to rebuild the engine with steel liners taking the place of the original cylinder walls.
Please see the pictures below showing some of what we did.
This Nissan GTR came in for a modified bell housing and sport cat downpipes.
The bell housing on the GTR is not one of it’s best features and even OE replacements and revisions still have an issue with noise and vibration. The replacement unit we fitted here solves the issue with a relatively simple solution. New rear bearing is fixed position roller bearing design instead of the ball race bearing. The retention of the front bearing is also improved for increased strength.
The sport cat downpipes allow for a faster turbine spool up due to less back pressure, therefor increased power output is possible with less engine strain.
We did have an issue with removing the turbo’s, due to the vehicle’s age and many heat cycles, all but ONE exhaust stuf snapped on the way out. So we had to split the turbos to be able to get them onto our pillar drill safely, drill out the old studs to replace them with stronger studs with thread inserts.
You can see from the pictures we had fun working on this GTR.
Our client Gary brought his R34 GTR in for healthcheck after a few track days. We checked the fluid levels, the suspension, engine and under the car to make sure everything is still tip-top.
The engine was recently re-built by us for a higher state of tune and is still going strong as expected!
For this Audi TTS we fitted a decat pipe and carried out a stage 2 ECU remap.
The unlocked BHP and torque is very impressive as you can see with the dyno graph below.
Check out this STEALTH MODE upgrade for an Audi A6. We fitted a Wagner Tuning Front Mount Intercooler.
This unlocks increased boost from it’s two turbos, plus enjoy a remap to suit!
A beautiful Ford Mustang in for Miltek Cat-back exhaust system and Roush rear valence to cater for the quad tipped exhaust.

This R33 Skyline has had a number of suspension upgrades, including replacement of nearly all the arms and bushes.
Now with an accurate fast road geometry setup, she handles like she’s on rails.
A returning client and his Nissan GTR visited us this week. His R35 GTR was in for a major service and healthcheck.
This GTR is very well looked after and is one of the cleanest we have seen.
This Vauxhall Astra van produces a staggering 450bhp with its tuned Astra VXR engine. The van was converted with running gear from an Astra VXR.
We carried out wheel alignment and a healthcheck prior to an upcoming trip to the Nurburgring! Sounds like fun to us we can’t wait to hear how she performs.
(Post updated 21/02/17)
Intercooler and Turbo upgrade on Audi A5. We fitted an uprated intercooler and a modified hybrid turbo and now the car is ready for ECU remapping. More updates to follow.
(21/02/17) The A5 has now been remapped and produces a very healthy set of figures. On the road she pulls like a train!
328bhp & 476lbft
Our client Ozzy brought his beautiful Audi RS4 in, this time for a full service, inspection and installation of a carbon fibre front splitter.
This car has such an agressive stance with the adjustable air suspension anyway, now enhanced further with the new front splitter!
Today we had an Audi RS4 in for fitment of a Miltek cat back exhaust system.
You can see the fantastic performance gains from this naturally aspirated v8 below where we did a power run before and after.
Run 1 (stock): 438bhp & 314lbft
Run 2 (w/Miltek): 456bhp & 330lbft
This is the second Impreza hatchback we had in this week!
The car came to us with fueling issues and engine oil leaks after having engine work performed elsewhere.
We diagnosed the fuelling issue to be a weak fuel pump, which we replaced with a Roger Clark Motorsport uprated fuel pump.
We have some pictures below of the oil leaks, as you can see we had some fun diagnosing and fixing the problems!
We like an Impreza hatchback – and this week we saw two of them!
For this Impreza WRX STI we carried out a FREE healthcheck, dyno power runs and 4 wheel alignment.
Our client Lennie leaves very happy and we even discussed future engine work…
Mini Cooper S fitted with a Water Methanol injection kit by Devilsown. This system is designed to prevent detonation which can occur at high temperatures and pressures in the combustion chamber. Water has a high latent heat content which makes it very effective at preventing the onset of detonation. The water injection also reduces the production of NOx (oxides of nitrogen). The methanol additionally reduces the chances of detonation due to its 116 octane rating and a performance improvement is achieved. A 50/50 mixture is misted into the engine which takes into account the fact the water and methanol will both reduce heat in the combustion chamber meanwhile the added octane rating adds BHP.

It’s time this M3 had an engine to cope with the supercharger.
The stock engine unfortunately suffered a failure, has been recovered to us and now we will begin planning and building an engine to take the boost!
Keep checking back for the latest updates…
25/02/16 – Recovery of car – planning begins!
26/02/16 – Engine is out!
We didn’t waste any time; the M3 engine is out and ready to be stripped. We will inspect internal damage and prepare for the build. When the car is being built back up we will be tidying up the car in general including fixing other minor faults.
Now the car is in the hands of Perfect Touch it will be looked after, ready to win medals…
02/03/16 – Detonation!
We have had a look at the stripped down engine and can show you what has gone wrong. Essentially the water injection system that was fitted to the intake as part of the Supercharging has failed and the cylinder has become too hot causing the fuel to ignite before it is sparked by the spark-plug. You can see some of the damage this has caused to the top of the piston in the picture below.
We have an update on the progress of the BMW M3 E46 supercharged build. The engine components are starting to arrive, some of which you can see in the pictures below – rods, crankshaft, pistons, injectors and Schrick cams. We are also discussing other plans with the client including engine management and transmission changes. Watch this space…
