Lotus Esprit 2.2L Turbo - Engine rebuild

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.

Vauxhall Monaro VXR engine rebuild and upgrades

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.

997 Porsche 911 Engine re-build due to cylinder faliure

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.

Nissan GTR modified bell housing and sports cat downpipes

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.

Nissan Skyline R34 healthcheck

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!

Subaru Impreza WRX STI hatch, fueling issues and oil leak

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!

Mini Cooper S fitted with Water-Meth injection

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. Visit http://www.methanol-injection.co.uk/  for more information.

The FIRST UK BMW M6 with manual transmission

We were lucky enough to be given the opportunity to handle the conversion of an SMG equipped BMW M6 to a 6-speed manual gearbox.

Manual? You ask…Did BMW even make a manual M6? Apparantly it seems they did – 701 to be exact (323 Coupes + 378 Convertibles) – but for the USA only!

The one option missing from the UK models was a 6-speed manual instead of the SMG, after all we are probably the best market for it!

Our client asked us to research and look into the best ways to convert his car over to a manual transmission.

As soon as the car arrived we set about removing the existing SMG gearbox allowing us to see the access available for linkages, clutch lines etc.

Our client supplied the manual 6-speed ‘box which was imported from the USA for a US M6, complete with clutch and flywheel.

We sourced a pedal box from a 530d, and hooked up the clutch lines from the pedal box to the master and slave cylinders.

We removed the perforated holes provided by the factory (how nice of them) so we could run all the cables and lines under the car properly, just as the manual M6 would be.

We had to have a custom gearshift gaitor built as this doesn’t exist for RHD 6 series, as all 6 series cars in the UK were either auto or SMG.

The engine ECU has had to be programmed to know that it now has a manual gearbox attached, otherwise as far as it’s concerned there is no gearbox attached and will only run in ‘get-me-home’ mode.

That’s about it, if you would like to know more you can call us on 01992 443900 or email [email protected]

Nissan Skyline R34 GTR

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
