CRX 1987 carb vs 1990 CRX HF fuel injection?

I still learning and my first goal was a Geo Metro or Honda VX
Now I am seeing a 1987 carburetor HF 5speed that is a time capsule. Really clean

Then I see 1990 CRX Automatic and not as clean but same asking price

Is hondas CRX carburetor not as efficient/reliable?

Thank you,

I'd snag the time capsule. Probably get twice the mileage of the auto. Carbs are fine until you have to go into them, if it's running right, the HF is the only choice.

I had an 84 1.5,avergaed 44 MPG without even trying but the speed limit was 55 MPH so not much over 62-65 on the Interstates.

Depends. My '84 always RAN just fine, and averaged 40+. The problem was getting it to pass smog checks.

I don't know if your title is a typo, but if the '90 is an automatic then it's not an HF? Or did they actually make those?

Carbs work great when they work. If the '87 is that clean then I would grab it. I have a clean '87 Civic that I'd love to drive, but the carb is actually messed up on that one, and sadly no one around my part of town has diagnosed a carb problem in the last 10 years, especially one with as many vacuum lines as mine! But if the '87 CRX is in that nice of condition and runs well, I'd take it.

I've seen many mis-labeled CRXes over the years. Especially in our area.

There was no automatic CRX HF in the US. They were all five-speed manual transmissions. If the car had an auto, it was a "DX" or standard CRX. The auto in that generation of Civic and CRX was not great, and its fuel economy potential is somewhat limited by the slushbox.

The 1st-gen car (first generation of CRX) has much more potential. The carburetors on those worked very well, up until they didn't. They are something of a pain to work on, from what I can tell, though not as complex as the earlier CVCC carburetors.

Anyway, if the 87 runs well, go for it. It's a little go-kart that doesn't accelerate very well but is exceedingly nimble and light weight.

Make sure you keep your head on a swivel when driving it, as it won't hold up the best in a collision. But that's true of most small vehicles--and it's far better to avoid a collision than to rely on your car to save you once you've gotten into one.

Compare Side-by-Side

The automatic in the 1990 CRX is EPA rated at 25/32mpg while the 1987 crx hf is EPA rated at 42/51mpg.

letting anyone removed any of the vacuum lines from a Honda carburetor is a bad idea, it's a whole system that is designed to work as a whole, so if something is missing then walk away.

There are a few things to learn to do with the carb on a honda, but if it's working well and left alone then most of the time they are just fine, avoid low grade gas.
