I watched this video and now I want to know if a 88 crx hf gets better mileage than the 92 civic vx? and if anyone has ever swapped the civic vx d15z1 vtec-e engine into an hf???Any feedback from owners of the two cars will be appreciated.As I'm planning to try this out. Here is the video the guy claims an average of 60 mpg.

Here are the engine stats. If the z1 is more efficient then it also has more hp. Which would make it a more desirable engine.

 

well it is 28 more hp so it wouldnt be bad
in the light crx

88 hf 1819lbs
the vx is 2094

go for it let us know how it pans out

 

anyone running a stock hf???

 

I'd go with the zc. But yea nice vid
