Lots of these things I've been wondering about - boost pipes, silicone this and that - whether it'll help the engine breathe a bit better and maybe iron out some of the hesitation and what definitely feels like a lack in power from when it was new(er). First thing to do is the cheaper stuff, so sorting the turbo vanes and cleaning the inlet manifold is the priority, then we'll see if that has any noticeable effect on power delivery and go from there. For what I use it for, I'm more than happy with the stock car, but if I can keep it healthy and running efficiently, I don't see why it can't last as long again as it has already.
If you clean the manifold and turbo at the same time then take the car out, itll blow your socks off .
The difference will be like night and day.
Dont forget to work the actuator.
