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…
24/09/17 – Power Run after remap
This EVO 10 was brought into us with engine damage, we diagnosed a number of faliures with the engine including a spun big end bearing, damaged rod and crank case damage.
We spoke to our client about what options they had and they decided to upgrade a number of components allowing for a safe increase in power with more reliability.
We supplied and fitted Marley pistons, Manley rods, ARP head stud kit, crank case stud kit and conrod bolts, ACL race bearings, a Commetic head gasket, Garrett Turbo-charger, equal-length header, downpipe, we renewed the timing chain and guides, skimmed the head, intake and exhaust valves cut and seated, new oil cooler and oil pump, Walbro fuel pump, injectors upgrade. To increase gearbox reliability for more power we have also up
Next up is to run in the engine over 500 miles minimum before dynoing and mapping the car.
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.

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.
Some of you may remember this R34 GTR, we had it in for a coolant leak, which unfortunately turned out to be a cracked block.
So a second hand N1 24u rb26 block was purchased.
We reused most of the Nitto 2.7 kit, the pistons were replaced, the crank had a very minor polish. When we came to reassemble the bottom end, we measured the crank to bearing gaps using plastigauge (can be seen in the pictures) and ring gaps were measured and adjusted If tolerances were to small. Now all the tolerances and gaps are perfect we proceeded to built the engine up using only the best components for reliability when this GTR is tearing up the track!
Once the engine was fitted, we run it in properly with religious engine oil changes, with the correct oil.
Now for mapping. And who better than Romain at Syvecs. He did a brilliant job with this car maximising engine performance and reliability. The car made just under 600 bhp after the engine was mapped, due to the turbos underperforming, so this is to be continued! With new turbos, this car will make 600bhp+!
Gary has his car back for now, until next time
We changed a fuel pump cam follower on this Audi A3 2.0TFSI.
“It is a very cheap part and isn’t a great deal of labour to change but in the long run can save you a hell of a lot of money! We have seen them completely wear through (you can see this one is starting to wear) and kill cams! Which is expensive and costs much more in time. Not many people know about changing this little follower.”
This Evo 10 is in the intial stages of a major engine rebuild…with some uprated components.
We are looking to get the power up to around 500bhp safely with new rods, pistons, turbo and other parts.

Our client brought in his EVO X today, the complaint was lack of power and the engine seemed to be running on only three cylinders…. he was right but little did he know his engine was running even with a huge hole in the casing!
More updates to follow, for now take a look at the gallery below:

The owner of this Porsche 911 came to see us after a recommendation. The previous garage had stripped down the engine and were unable to take on the task required.
As the engine was already stripped down we were able to immediately inspect the cylinder walls and determine the issue. The cylinder walls on the naturally aspirated Porsche engines are Nickel Sealed Aluminium and are known to suffer from cylinder pick-up. This is where as the piston is moving up and down inside the cylinder it makes enough contact to gradually strip away this Nickel Seal, leading to loss of compression.
After we spoke to the customer it was decided that to replace the cylinder block it would be worthwhile in fitting the existing cylinder block with brand new Steel Liners. This would ensure that in the future this enginer would never suffer the same issue.
Take a look at the pictures below to see some of what was involved
