Sorry can't help much there as I have a 130 so I don't know the diameters of your current connectors but if they are none bayont type you should just need some silicone reducers and clamps to fit the alloy \ 1.8T IC and maybe a different MAP sensor depending on the diameter of yours.
If you went stock 130 route you would need a different pancake pipe, small pipe from that to the IC, and then the pipework from the EGR down to the IC - this can be the expensive option and not too reliable due to the bayonet connections
