However, GM never made a good 60 degree engine. They all leaked coolant into
the cylinders or oil pan.
You will be right at $3k if you get all parts from the junk yard.
With a lot more money you could install a 3.3 or 3.8 90 degree engine.
If your country has vehicle inspections it could be a problem.

I had a 2.8, two 3.1's, and now a 3.4, all 60 degree. None leaked
coolant. That series of engines was the GM mainstay for a couple
decades. I think the 3.1 Gen III had some intake manifold issues, but
not as widespread as the 3.8 Series II. That one had more widespread
failures, but was easily(?) remedied by updating the gaskets and upper
plenum. My son and I did that to his '95 Bonneville. Parts cost was
When I was a teenager, engine swaps were done all the time, usually
big V-8 into a small car for some really crazy performance. Not so
easily done today. Limited space, more difficult to adapt to trans
mission, special exhaust may be needed.
You may also have issues with emissions controls too.
Unless your Cavalier is really something special in condition, I'd
invest that $3000 in a newer car with the performance you want.
