Maybe the lean burn engine was designed with the better aero and taller gearing of the HF in mind?
Didn't the crxmpg.com guy (forgot his name on here) get really good gas mileage with his HF gearing in his CRX? If I recall he had dx gearing to begin with and then swapped in the HF final drive and said it was awesome.
