I was going to buy a new car next year but it seems stupid to do this as my ST170 is mechanically brand new, aparts from the engine which is low milage, every other mechanical/suspension part has been replaced or rebuilt. My plans now are to remove the engine next year rebuild it and add a turbo

I want a reliable 300bhp and need a shopping list, i want to retain the VVT so what managment, manifolds, turbo, rods & pistons would be reccomended. Once i have the shopping list i can start collecting my part.
Thanks i know its going to be expensive, thats not a problem. I know i could fit an RS lump cheaper probably but i want the car to remain as much ST170 as possible
