Megane 225 no start issue

Evening all, for some reason I bought another meg 225 I really don't know why was more of an impulse buy.
Anyway the car was a none runner when I got apparently the fobs didn't work or start the car and it wouldn't crank. So I fitted a new battery to the car when. I got it and hey the fob unlocked and locked the car and the car cranked (did not start). Also noted that I had keyless entry which was unexpected.
Anyway so I done compression test all 4 perfect, checked fluids and again all good. I then removed the sparkies and replaced with new OEM ones, I also replaced the coil packs with brand new, car still didn't start so I thought let's check fuel to rail and yep loads of fuel. I bought a brand new OEM tdc, and brand new OEM injectors and guess what I still have the same issue.
The car cranks over coughs then dies anyone have any idea's? I am thinking it's spark related as the spark plugs are wet, I have removed coil pack 1 with spark plug and it arcs fine dueing cranking I'll try the other 3 tomorrow.
Do we have a wiring diagram for a 55plate 225?20160714_132542.webp 20160714_132459.webp 20160714_132420.webp 20160714_132333.webp 20160714_112831.webp 20160713_112305.webp 20160713_092924.webp
 
Ok looks like the turbo is pretty fecked off boost driving is really nice no smoke but a little bit of positive pressure and black smoke and what sounds like blades hitting the housing's.

What turbo's are these and do the newer RS250 turbo's fit?

The meg parked up with the other project's lol

I didn't have enough money to go stripping the engine properly to find the issue. Have gone for a mk3 engine swap, they have better designed Pistons and a rising rate fuel rail. Hopefully I can run the same power but with plenty of margin for safety.

You should be able to tonk past the power :)
A very safe 320hp and similar torque
