D15A2 from CRX HF. You'll need to use premium gas and you won't be going anywhere fast, but its ridiculously efficient.

OneBadTurboCRV

More like a '88 CRX HF as a whole... unless you pair it up with how the car was designed from the factory it won't perform as well.

There is a guy that took one and is getting over 100mpg on one. The average stock HF gets around 50mpg easily if you follow the shift light. Sad when you consider what today's HYBRIDS can't do... Ahh, the greed of corporate America.
