Little update. I've now added a Walbro fuel pump. Mounted it under the car rather than in the engine bay like some. I'm still trying to keep the bay as OEM as possible.
Also decided to buy a new turbo. My car still isn't boosting right. Most of the time it will be okay, but the odd time it will overboost as before. I've been though everything and the people I've spoken to all suggest boost creep or a cracked turbine housing. Whatever is up, it's whistling above 22psi and I need to keep watching the boost gauge. Can't reliably boot it.
So in the search for a better unit I grabbed a TD05H-18G hybrid. It's a Blouch item sourced through Scooby Clinic. Has a 14psi actuator and a ported turbine housing to hopefully eliminate all boost creep.
Thought I'd post a few pics how it arrived and after clocking the housings for the 1.8T.
As it came:
18G vs K03
Oil and water fitting removed.
Turbo disassembled:
Pin in turbine housing that nedded to be removed

Back together with housings pointing in the correct directions:
Just need to weld on a couple of bosses to bolt the actuator to (area circled in pic). Shouldn't be too difficult. Bought some aluminium offcuts off ebay for the job.
Not sure when I'll get stuck in fitting it. Going to do the engine work at the same time. I'm waiting on some machine shops to get back with prices on some head work. Mainly fitting the new valve guides. If anyone knows of a good place in the south, then let me know.
