Thanks guys , i have already fitted a group a coil but stopped short of getting coil pack conversion , the fuel pump has been re wired already with separate fuse, and the £1000 pound price is due to buying all the gear as stated above , new -31 actuator , new 3 bar map sensor , new 803 greens , one closed loop chip , and the cost of the rolling road time plus labour to fit ,
I have been told the 4x4 intercooler is good for 350 -400 bhp so i am leaving that for a bit i will get an rs 500 style one soon

thanks for the comments
