Driving an H22 car is different yes. But correctly tuned suspension and good wheels and tires the and car will drive just as well as an B or K swap. The H22 will destroy any gsr swap stock for stock.
Is the K-series any heavier than the B? I would say that you better make plans for a good suspension setup for this too.
