First, figure out if your manifold has a trapezoidal cross section at connection to crossover pipe, or a "D" Shape cross section at connection to crossover pipe.

Then search here:

If this junkyard search engine is correct, it appears that manifolds from non-supercharged will swap. $50 seems pretty common.

Well, using the car-part.com search engine, for a "D" shaped crossover connection and for '92 supercharged SSEi, it pulls up '91 and '92 model non-supercharged Olds, Buick, and Pontiac: prices from $35 to $115.

For the trapezoidal shaped crossover connection (this is what my '95 SLE looks like) it pulls up SSEi only for '92 plus Olds Buick and other Pontiac models '93-'95 .

Looks like the '92 SSEi got the newer trapezoidal design late in the production year and GM ran with it from '93 to '95 before changing.

Anyway, unless the search engine is bad, he should have lots of inexpensive options.

I just went out and looked at my '92 SSEi. On it, the front manifold appears to be one continuous peice with the crossover pipe. There is a flange at the rear though. DGP is looking for the rear crossover pipe.
