all i know is someone called chris used to own it and be on here, and i believe he did all previous mods, only things ive done is add collins bov, make the IC piping 2.5 inch all the way through to the throttle, done deletes, tidied up the spaghetti junction vacuum lines, put a 4 bar fpr on, added a direnza alloy rad and done a one of custom turbo inlet pipe instead of paying the rediculous prices pro alloy charge, i have a kemso 340lph pump to go on in the future and have used one of these for 3 years straight with no issues on my previous coupe (reg R629 LVV)
