I have run my car with an A14 and also a CA18DET.

While the car is a lot faster these days with the CA it no longer has the crisp turn in and mid corner adjustability that it did with the lighter motor. I tend to drive it more on the throttle than simply via steering input nowadays (I hope that makes sense).

I wouldn't say it handles worse these days but it isn't as much "fun". Fortunately I have also owned Bert's 1000 coupe for the last couple of years for that.
