ok, I got the car to Chris, who used to run an R5 groupN in Rally championship, and he installed a T25, samco hoses, Forge dv, dual cap intercooler and logically put in the cup circuit which I had not before.

Because I still need to go through technical inspection in Belgium, we kept it on low boost (1bar --> lowest with the Colin actuator), but man does she run already :mrgreen:
The difference is amazing, the tires keep burning until you shift to 3th if you want too, love it!
After we get things registered, we'll get the groupA carb, correct jets for higer boost and we'll turn things up a bit.
From 0-60mph it's already faster than my old impreza gt turbo.
