i was also told that an L1 ecu was from a 3dr. the chap i bought it off had t34.55 housing and rs500 intercooler on his 3dr. i dont want stupid amounts of boost just something more than standard. around 280/300 bhp i would be happy with as i have been told they are ok around that as i want reliability and not to have to keep spending on it everytime i drive it. cheeRS
