can you.....?

can you convert a carbed 1.8l to a fuel injected 1.8l if so u could give me some advise and also do the f.i. have more power and better gas mielage

The FI does have more power, and you can convert it. However, part of the increase in power comes from a slightly higher compression ratio, so you wouldn't get as much as a factory FI car. In comparing the numbers on my carbed 86 with a Weber 32/36 DGEV, I get about the same mileage as most people I know who have FI, about 27 MPG.

what kind of carb do u suggest im looking to get better gas milage and more power maybe?

I got better mileage on a stock carb'd EA82 wagon (30mpg city/highway loaded down) than I get in my MPFI turbo sedan (25 or 26mpg city/highway).

 

If you want more power I always hear about Webers...

I have a Weber 32/36 DGEV. It's got an electric choke and it works really well. You just need to set up the jets correctly. It's a pretty common conversion.

thanks

Yea, now that I finally figured out the jetting, I love my Weber!! Regarding the FI conversion, I read the manual, and decided I'm too stoopid to handle the electronics.

is figuring out the jetting hard does it take lots of time

 

thanks nick

Real good write-up on tuning the Weber. As far as amount of time, that would depend on what the carb is now, and your abilities in tuning it in.

Here's what I think about that, and first let me tell ya I'm far from being an expert. In fact I didn't know squat about carbs when I started trying to get my used Weber to work on my lifted wagon.

 

If you buy a new one from a supplier that provides the carb jetted for your engine, then your in good shape, and have a base to begin tuning. I'm getting the impression that ther's not much farther to go from there. Probably won't have to change much, if anything. Maybe just some adjustments.

 

On the other hand, if you pick up a used one from a different rig, then you have no idea where your at. Or where to start. This was my case anyway. What really took the most time for me, was trying to find out what jet's were SUPPOSED to be in there. Once I found that information on the board here (I had to dig, it took a while), then tore the carb down, and replaced the jets with what I was told Redline puts in for our Soobs, every thing started to work much better.

 

There's a huge amount of information over on the "Off road" section.

 

Good luck and have fun.

I happen to have an O2 sensor in my exhaust, because I had to replace my Y pipe. If you have an oxygen sensor, it makes it really easy to find the right jet combo. You just hook up a voltmeter to the sensor, positive to the sensor and negative to ground, and check the voltage under different operating conditions. Realize that the 32/36 is a progressive carb, so the secondary opens mechanically at higher rpms, and it also has a separate idle circuit. You are looking for a voltage of approx. 0.48 volts. Higher is a rich mix, lower is a lean mix.

 

Some of the vendors are better than others in providing helpful information. If you tell them what you're running the carb on and what altitude you normally drive at, they should be able to get you really close.
