My MKIII - My Project - Need a few answers

[Grandavi]

The whole turbo issue is going to be a "Read/Get Advice/Plan/get plan approved/do" issue as this is my first ever turbo vehicle. This forum is an excellent resource, but actually having parts in your hand is the best teacher. Its just not the area I want to make a mistake in.

I think to do it properly, i need to change the downpipe, add(?) a wastegate and blowoff valve?, putting on a timer (regardless, that is my first thing to do), and I dont know anything regarding spikes. (think the timer solves that, but not sure)

Its a learning curve
