This page has three main sections: 1) ECU Options, 2) Kit Upgrades and 3) Optional Extras.
1) ECU Options
As outlined in the Introduction, the kit contains all the mechanical parts required for the Honda engine conversion. To get your engine running, there is a decision to be made about the ECU. Firstly, to overcome the ECU immobiliser and, secondly, to allow the tuning (remap) of the engine for maximum power.
The three main ECU options are:
i) use the factory ECU with an immobiliser bypass unit
ii) convert the factory ECU into a mappable ECU with the Hondata K-Pro upgrade
iii) use another aftermarket ECU of your choice.
The electrical instructions provided with the build manual contain all the information required for ECU options i) and ii). If you choose a different ECU per iii), then our instructions will help to some degree but it’s a much bigger DIY task.
Pricing for ECU options i) and ii) are as follows:
|i) Hondata K-Pro ECU upgrade (latest v4 now available). Highly recommended to help extract the maximum performance from your engine and our sports exhaust system, the latest Hondata K-Pro ECU package converts the factory ECU into a fully programmable ECU. The upgrade includes fitting the K-Pro board, installing a USB port so you can hook up your PC/laptop to the ECU and the programming lead. You also get access to various base maps to get your car started, K-Manager software to adjust a multitude of settings (including enabling/disabling the ECU’s built-in immobiliser), onboard data-logging and bluetooth connectivity to name just a few features. The standard ECU from your donor package will be required on an exchange basis or we can supply a donor ECU. We recommend your car is mapped on a rolling road (dyno) once the conversion is complete.||Hondata K-Pro v4 £529.17 + £18 shipping to/from Hondata. Used donor ECU (if required)£85.|
|ii) Honda ECU immobiliser bypass box. The original Honda ECU usually has a built-in immobiliser, so if you don’t want to go to the expense of a K-Pro or other aftermarket ECU, then you will need one of these “black boxes” to start your engine. Not recommended for long-term use as your engine will run lean with our kit’s sports exhaust manifold.||£148|
2) Kit Upgrades
As the kit is extremely comprehensive, we offer just a few upgrades alongside a range of Optional Extras.

See below for clutch and flywheel options.|
