I beleive you need an motor with an SG shaft, so that one wont fit. Plus the GT2 comes with a rear exhaust header, if you get a side exhaust motor (like that CVR) you will need to buy a new header (which is easy to get). The carb on all motors can be flipped around to fit different cars. SO looks for a SG shaft, rear exhaust, rotary carb engine. I think you could use a slide carb (probably doesn't include the linkage for it though) on it as well, but the rotary carb is easier to drive.
