turbo help please

[GT Phayer]

it comes up from vaccum and stays on 0 mate

does it stay on 0 all the way through the rev range? ive heard that the td05 can only create boost when the engine is around 5000 rpm on the 4efte. yes the piping is correct on the wastegate, the pipe needs to go to the compressor side of the turbo. and if your not creating any boost check to see if the external wastegate is being held open. this will cause the gasses in the exhaust manifold to basically bypass the turbine in the turbo. but it will sound like there's no exhaust on the car.

all the way to 7000 rpm and i get alot of exhaust noise not screamer tho and ive tested the wastegate with a compressor doesnt seem to be sticking.

has the old wastegate i.e actuator penny washer been blanked off i.e left closed?

[GT Phayer]

its been welded shut mate

[GT Phayer]

well i took the turbo off and the penny is welded shut and has not failed so put it back together and double checked everything and still no boost

[Flaminsam]

this is a strange one. its asif the engine either doesnt have enough flow to spool up the turbo or the gasses are bypassing the turbo completely but i dont see how that can be?

I would be getting a remap before any boost ups you want that mixture spot on, might aswell get a ebc and map at the same time...
