Recommended Tuning Levels

 

We have included this section us a guide to what we consider to be the most cost effective steps during tuning. This has been compiled with the benefit of experiencing hundreds of upgrades. There are other parts/turbos that can be substituted but the listed parts we have found to give the most consistant results over many installations.

Your own ideals may vary depending on the parts you may currently have fitted.

Our suggested levels are compiled to mimise incompatible components, it is not ideal to fit a turbo that your fuel system cannot support for example,

We do not do parts fitting here and therefore do not put complete pricing info on each level, the components in the tuning stages are listed in order to allow you to select the most cost effective route to power and in turn allow us to achieve the best results from your car. The price of the individual parts can be found on the other pages.

Our core business is ECU Custom Mapping and Hybrid turbocharger design/building. We are not here to try and sell you the parts with the biggest profit margin, we can however supply (for local collection or mail order) all the tuning parts listed if required. Optionally you can source them yourself or arrange for the garage doing the fitting to supply them.

We can recommend specialist garages within a 100 mile radius that work with us on a regular basis to fit the parts if required. These garages have been specially selected as places that are very experienced specifically with Subarus and work on a daily basis with this type of car. We recommend them as we know they will look after your car and their attention to detail will ensure maximum reliability. It is perfectly safe to have the parts fitted and then drive to us off boost (this still allows cruising at 70mph) for final setup and custom mapping. We have had cars drive over 400 miles to have this done.

Predicted BHP figures are approximations, our section on “rolling roads” explains in some detail why it is impossible to give exact figures.

Due to the many engine variables throughout the years and models we have sub divided into 10 major categories

92-96  UK/WRX/STI/RA (except JDM wagon)

97-98  UK/Euro/WRX

97-98 STI 3&4 & 22B

99-00 UK/Euro/WRX

99-0 STI 5&6/ P1

01-05 UK/Euro WRX
