ive posted a few things on here asking for help as i thought my car was fuel cutting at high speed. turns out its restricted. can anyone shed some light on what i can do or buy to derestrict it and/or tell me what derestricting a 1994 wrx import actually entails? thanks in advance for all your knowledge,

 

It will cost you £50 for it and will take 5min to put it in it is a little tube like thing that attaches to your speedo cable where it goes in the back of your clocks. call Howard on 01422846868 I think if not look up HDC subaru in google he sells them and will get it next day.Failing that you can get them off fleabay

 

will this thing actually derestrict my car from 112mph to more? or are u talking about the kmh to mph conversion?

 

IT does both I have it and I imagine so do alot of others
