I believe Larry A.K.A. Twisted6,, said the SPA turbo manifold will not fit the early Novas,the turbo will hit the shock towers/structure.
There are a few fast cars I have seen run the STS system,there is a lot more tubing involved,electric oil pump,feed & return hoses for the oil & so-on. They don't seen to have turbo lag problems,but you need to choose the correct A/R for the turbine housing.
You can run a "J" bend pipe from a stock exhaust manifold.
Here is REVOD from the BB here did one in a newer Nova,but you could fit one of these & be a low dollar install & make it fit your engine compartment.
