IT will be just like any b-series motor, they weigh all in the same ball park.
No, it will not be like an H22, but even they aren't really too much of a problem with the propper suspension.
You won't have any problems that you can notice, especially if you have to be asking this question. If you were an autocrosser, then you probably would notice a difference, but otherwise it will just feel like your D16, just with a lot more power.....
