ihi vs t/3t/4 questions

I am rebuilding a 88 tc I also have a merk xr4ti
my problem is the guy we got the tc from torched the egr pipe off the back of the turbo as well as the studs that hold the exhaust downpipe on and cut the oil return line. will a t3t4 oil return work cause I have one of those and will the ihi bolt to a t3t4 exhaust manifold. ?

The T3 return line won't bolt up to the IHI flange - they are different sizes. If you got the stock exhaust manifold (E6) the IHI will bolt up

thanks
