At the moment the car isnt road worthy, its solid but isnt running great, takes a long time to start, boosts at 4k and is dead as sand before that.

I'm completely out of my depth with this as I've been a Vauxhall for years and before when I had RSTs, I just drove them and no more. lol I dont even know what Boost is! lol

So, the engine spec list:

Service
Chip (if its not already)
Intercooler
then maybe a larger turbo?

Brakes:

As Cossies are hard to find here, anything else that could donate its stoppers?
