Right, these turbo are quite easy to get hold of now, so this is a reminder to anyone who is thinking of getting one and post results... ;) lol

if you are not able to get one i can ask my friend to do another one, we also machined the bolts out of the oem high temp strange ones (not shown on the pictures)
you are in need to deck the adapter after the welding

Thanks for that. What is the reason for the bolt holes if the plate is being welded on anyway? (sorry if this is a stupid question)

I see (didn't pay attention to the pictures) So the plate is welded to the manifold, studs tapped into the plate to bolt to the turbine housing..
Can the compressor outlet be easily plumbed into the stock charge cooler?

REALLY must teach myself to weld. I have a welder and done a bit but my work always comes out looking like pigeon guano! (still gets through the MOT though...)
Nice heat shield. What material is that?

The heatshield material looks like Nimbus G2 to me:

How are you running your water ways as I thought they had to be setup , with entering the lower side of the chra to the higher

like:

Also can you tell me the size of the plugs you used on the anti lag ports of the corolla manifold
