Pulleys are the same. Yes

ICV pipe goes from the main intake pipe (where the filter is) to the ICV itself.

Hmmm maybe its missing and that's your problem?
It's attached the throttle body and is kinda underneath the cable. Has a little pipe connected to it.

Look at your throttle body the icv I on the back of that ? It's black and held in with 2 m8 or m10 bolts. You can change it or try cleaning it ?

Fuel and smoke dripping out of the throttle body...Erm?

By fitting the Wossner pistons have you altered the compression ratio?

Yes, you should be swapping the fuel pump over to the GTi-6 one. Yes

When you say the pistons are high compression ones, what compression figure do they actually give? The standard pistons give a compression ratio of 10.8:1. If the pistons you have installed have altered this then the engine's mapping will need to be changed to accomodate this.

And to answer you other question.

High compression is for na engines the higher compression the more efficient the mix of air and fuel become which produces more power.

Low compression is for turbos- your throwing compressed air into the chamber.

That's the basic explanation anyway someone else could probably tear that apart Wink
