Owners comments:


The car was bought from new with no plans for modifications when i was 22, after 4years of ownership i was starting to get bored and old enough to get get insurance when modifying.
I then tinkered with it and did the basics of induction and exhaust improvements and the bug bit.
After doing some research i decided to get my hands on a set of "wingy" spec injectors, but realised i needed to provide a platform that work in harmony with these and so did the prepwork to get the non engine side beefed up.

After a few years of development work, decided to stop using the wingy spec injectors and revert to a new hybrid injector no-one else had tried - This enabled me to make use of the other modifications to get good power\torque without the very high EGT's and smoke the wingy injectors seems to provide me with. 

Green run in image below was due to ECU mapping to suit the previous injectors - red and blue were the corrected dyno runs with the fuelling sorted out.
