Essex Honda Conversion

Known as the most refined Honda conversion available, we have worked hard with suppliers of engine mounts & driveshafts to ensure that our Honda conversion exhibited quality in excess of a factory built car.

Many development hours were spent perfecting the gear shift mechanism (unique to our kit is the Honda counter-weight to give production quality gear feel), honing the refinement and drive-ability, as well as ensuring fit and finish in the engine compartment is of the highest standard.

The kit offers an effortless 220hp from the super reliable Honda K20A unit, revving to a heady 8500rpm, this truly is the engine that the Elise was designed for!

Superior fit, finish & engineering.

We are confident that you will not find a better Honda K20A conversion for the Elise/Exige/340R anywhere in the world. Precise gear shift, minimal engine vibration, blistering performance & total proven reliability.

Essex Autosport Honda conversion

The Essex Honda conversion betters the competition in comfort, reliability and attention to detail.


Varying strength rubber mounts hold the engine securely yet do not transmit harsh vibrations through the car. Just because a car is fast doesn't mean it has to be unbearably hard!


The engine is set slightly further back in the bay to allow the driveshafts to sit at a less severe angle, eliminating overheating and premature wear of joints.

Driveshafts have been specially designed and manufactured to withstand hard driving. Using Honda inner tripoid joints with new custom shafts and outer joints, any issues found in other kits do not exist in ours.

Our gear linkage setup can be finely tuned for a lighter, smoother and faster gear change. The original Honda counter weight is kept to help keep the motion light and precise.

Parts are of the highest quality to ensure reliabilty and powder coated for a great looking finish and longevity.

Each conversion is individual and finished with superb attention to detail.
