D20 to D23 in a ZX3..has anyone??

Is this the easiest swap? are the mounts pretty much the same? Electrical? The 2.0L dohc to 2.4L dohc was a fairly easy (relative term) swap in the 1st gen neons, would this be likewise? basically I'm thinking a ZX3 S (lightest chassis) with the ST (best power/tourque) combo.

Should more or less work out. But that's a lot of labor for just 20hp.

talk to FocusSport... they have a 2.3 in their Test Car... but I have talked to Randy at FocusSport before. As long as u have the block/head, everything will bolt right up. The only difference in a 2.0 and 2.3 is the Intake Manifold. Altho they may look the same, the 2.3 Intake Manifold has an extra sensor for the runners. The 2.0 however does not. But as long as u keep the 2.0 Intake Manifold, u should be able to drop it in with no problems

So the 2.3L is basically a stroked 2.0L then? Is the block longer or the same?
