Info Thread -
I have just been speaking to a company that have fitted kits to several turbo cars including Cosworth, XR2 turbo etc ...
They will be doing an Evo IV in the next few weeks and will keep me informed of the progress.
Kit will run at about £1500, water injection is advised aswell.

 

what a fantastic idea add about 8 deg of timing up the boost to around 1.5 bar ??????larger injectors hey bingo should see around 350 hp @ the wheels :-))
not bad for an every day driver :-)
