Here is proper video of the car running, there is a lot of smoke because of the rebuild so need to burn off the engine building grease and also running a very strong premix just to be safe, so almost double the normal amount of premix to petrol, so very smoky :)

I know its a chinese turbo but have researched them and all the V8 guys say they are perfect if you not looking for huge numbers, over 600bhp and my goal is 450bhp-500bhp so won't be an issue.

Going to clean up the exhaust housing and treat it so it doesn't rust further, just need to get a turbo blanket now.

Pics with the turbo tested fitted below.
Just need to spin the exhaust and intake housing so that the oil return and feed are in the right location as well as the intake exit pipe for the boost pipe to fit to the intercooler, will be fabing up a 100mm downpipe as the new exhaust housing is 100mm to fit the rest of the exhaust which is 76mm with a V Band on downpipes and decat, should give me a better spoil rate and as the turbo is twin scroll and my manifold is also made up for twin scroll should see boost building from 3000rpm :)

sorry for the poor quality pics, was in a bit of a rush.

Hahahah, yeah man "small hands"

I use the VHT spray paint, bake it on, it will come off eventually with the heat generation from the turbo but stop the turbo from rusting while its sitting.
