I just would like some other opinions.

Generally, I've been well pleased with my '87 CRX. 4 times, I've gotten
62. somethings mpg on trips. My last trip in cooler weather; I still cracked
60mpg.

I have read that the very 1st CRX with the 1.3 had a 4spd. Other data tells me the 1.3 had a 5spd. Can anybody confirm either way?

I also heard that the 1.3 was a 10-1 compression engine that required
premium fuel.

Would it be fairly easy to change a 1.3 found in a Civic body, and change it
to perhaps 8:5-1, or 8-1 so it could run regular gas?

The acceleration would be slower on the bottom end, but the key thing I'm
drooling over is it was the only CRX to have mid 3's for a final drive ratio.

It would seem like mid 70's mpgs would be possible w/o so much as even headers!

Any thoughts?

Thanks for any input!
