got the new turbo today. I was under the impression that the t3/t04e no spacer was required. well turns out i need one as well as longer studs in the manifold. .
My question is can i machine the spacer out of aluminum? 6061 plate stock.ive got a bunch here and it is already 1" thick

Turbine side on new one much bigger than old one , is bigger than it looks . Old turbo on the left is wimpy

Negative, ghost rider.....

Aluminum in the exhaust that close to the motor under those kinds of presure is a no-no......

The melting point of aluminum is much to low to consider using it under those conditions

Go with a 1/2" spacer in mild steel. HKS sells one for about 20.00 ready to bolt on, but you may want to port match the whole setup to the sixe of the spacer. I would highly recommend port matching the exhaust manifold and the turbo inlet to the spacer.
Just out od curiosity, why didn't you use a stock Nissan exhaust turbine housing?

I have the flange for the downpipe, and you can use a standard T3 flange for a spacer.
