The turbo motor, without the turbo, should be pretty disappointing, because one of its main variations (from a normally aspirated, or n.a., engine) is that it has a much lower compression ratio, maybe only 7: or 8:1, to tolerate the turbo's boost. But this will be disappointing without the turbo -- the n.a. engine is around 9:1, and I would guess that a 7: or 8:1 engine would put out maybe 80 horsepower.
Other differences, i.e., ignition and fuel mapping, abound as well.

So it's probably better that the whole engine was replaced with a n.a. version -- at least you've got a GL car :-). Just hope you didn't pay too much, thinking you were getting a turbo.

Good luck.
