i got a 94 supra TT and the twins went bad and order a used set of twins for it but look likes it came out of a different year. I was trying to use the new twins on to the old manifold but did not fit because the exhaust housing are design different like the 94 twins are smaller than the used new one.ANY HELP???

The twins never changed between the years to my knowledge. The only differences were between USDM and JDM. You may have JDM twins now or had JDM twins before? How do the sizes compare between both sets?

Whether it is USDM or JDM, they should fit on the 2jz head. IIRC, the only difference is the USDM ones have steel shafts and what not and the JDM ones have ceramic.

But he's trying to use the old manifold.

OP - did you not get an exhaust manifold with this 'new' set of turbos?

I have both of the manifold but on old one the back turbo has a four bolt flang that gose on the manifold and the new used turbos has a three bolt flang and another thing that i notice was that the peice that bolt on the downpipe is also different because one has very long stud and one have short stud.
