would this be possible? i could get those real cheap at a junk yard, i know the old turbo TA's turbine is small, but the turbocoupe has the mustang svo one (garret T3). so the manifold would bolt right onto any SBC and the T3 should bolt well to that...with an oil line made with a T fitting from the oil pressue senser and a return line into the oilpan, this would work right? oh ya and a blowthrough carburator

 

No. The 301 is a Poncho, so the manifold will not bolt up.

 

Not all thunderbird turbo Coupes have T3's
Some have small IHI's........
lol you could always get a turbo of a cummins diesal dodge ram!

 

The manifolds won’t work, like someone already said, it was a Pontiac block.

All T3’s aren’t created equal, the largest turbocoupe T3 (early 5 speed cars) was a 60trim/.63, where the 301 turbo used a GM specific 60trim/.82 that had a GM style flange, rather then the normal Garret one that almost all other T3’s use.
