Actual gas mileage of VX to CRX HF Swaps

[Davo53209]

In this post, I'm looking for those who've actually performed an actual D15Z1 engine into a CRX HF, while trying to determine both the actual city and hwy mileage that they've been able to achieved. If you've done this, please chime in. I like many others would like to hear about your results.

So far in my most recent post, I've been told that a realistic expectation could average somewhere in the high 40's for city mileage & somewhere over 60mpg consistently for hwy mileage. 60mpg on the hwy is impressive to say the least; but why such a disparity for city mileage? Is anyone able to confirm this? Given that the CRX HF is significantly lighter than the VX, plus having better aerodynamics, I would have presumed that such a swap would lend the city mpg closer to the mid 50's.

Thank You.
