hi i dont know if someone can help me i have a 98 uk impreza turbo (wrx apparently) and i was wondering if a version 4 sti ecu would fit and if it would be a straight forward plug and play or if i would need certain other bits done to help with the running of the car.
any help would be much appreciated thanks

 

physically yes BUT the differences between the UK engines and STI engines would most probably mean it won't work.

UK classics are Turbo 2000 only import classics were called WRX

 

thanks alot for your reply much appreciated mate
