Re: Weber 32/36 vs. 38

the 38 is basically for engines with preformance cams......the 32/36 is what you'll want for a mostly stock 258 or 4.0

i think the 38 would bog down your motor when you gun it

hope that helps....and as always..correct me if im wrong

Re: Weber 32/36 vs. 38

The 38 doesn't bog mine down and my engine is pretty much stock.. I've been really satisfied with mine, but I can't tell you how it does compared to a 32/36 because I've never used one.

Re: Weber 32/36 vs. 38

the 32/36 is supposed to be better for crawling and off camber stuff as well. I have a 32/36 but cant compare it to a 38 cause i never had one.

Re: Weber 32/36 vs. 38

Can anyone give me some details about the fuel pressure regulator that is required when using a Weber??? IE where it mounts, the reason for it, where I can find one, and if I really need it, etc. I will be putting the carb on an 87 YJ with a stock I6 except for the TR upgrade. Thanks!

Re: Weber 32/36 vs. 38

You will mount the fpr AFTER the filter on the fuel inlet line. You need to run it at about 2.5. Your fuel pump puts out too much pressure for the Weber, plus the use of the fpr helps very much in bumpy or non-level situations, helps keep a constant flow to the float chamber. I've had one for about 2 1/2 years with a 32/36, love it. I think it probably is the closest you can get in performance to fi without going to fi.

Re: Weber 32/36 vs. 38

Thanks for the input guys... I had found the Weber Carb web site, and read about them... Looks like the only difference is the 38 gives better acceleration, and power (also cost about $20-$30 more). Less mpg improvements vs. the 32/36. I'll find the web address and repost it... Seemed to have misplaced it right now...

Weber tech guy says, fp reg should be used if fuel pressure is above 3 psi in the vehicle..

Re: Weber 32/36 vs. 38

One thing about the 38, seems most complaints I've heard about bogging are with the 38 on a stock motor. It is just a little too much carb. And as far as the fuel pressure of your stock pump, I believe it will be about 7-8 lbs., I seem to remember that range from when I checked mine before installing the Weber.
