I switched from HIF-4s that badly needed a rebuild to a Weber 32/36 DGV, as I found out it was cheaper and quicker to buy the Weber than it was to send the HIFs out to get them professionally rebuilt.
HOWEVER, I'm switching back to the SUs.
The Weber does perform decently (better than vacuum-leaking SUs), and gets pretty good gas mileage. But I feel like properly rebuilt SUs will give me better performance...plus they're original.
I heard that the Weber was more reliable, and I was planning on using my MG as a daily driver. Yet I rebuilt and tuned the SU carburetors on my Healey and haven't needed to touch them with a wrench for two years.
What I now plan to do is just have someone rebush the SUs for considerably less than an over-the-top rebuild, then complete it myself.
Hope this helps.

Just my opinion, but I would stick with the SU units. I ran the same set for years, with leaking shafts and other issues, and I finally broke down and I am having a set done for my by Jimmy Hilton. I would have had Hap do it, but he is backed up with work right now. I am not sure if Jimmy posts here, but I know he is on one of the other MG boards.

If it costs around 600 bucks for a new Weber set up, I have one on the shelf, and it costs 360 bucks to have the SUs rebuilt like new, I had that done by Hap, then how do you figure your saving money by buying a Weber? If you have a late model single carb setup, then maybe a Weber will help, I don't know, but to throw away a pair of SUs and opt for a Weber is not the answer. SU carbs are almost bullet proof. The problem with them is, most people don't understand them. Notice I said earlier, I have a 32/36 set up on the shelf that I see every day. It's in plain sight, reason, to remind me not to waist my money again on a supposidly quick fix. JMHO. PJ

I bought a new Weber kit for $336 (which is still the price I find), and was able to finish bolting it on probably a few days after I got it. I don't remember who I called to have my SUs rebuilt, but the cost I was quoted wasn't $360..more like $500.

My two pea:
SU's ~ARE~ bulletproof. /bcforum/images/%%GRAEMLIN_URL%%/devilgrin.gif Set 'em an' ferget 'em.
Only Weber conversion for a B is a DCOE mod, and that only if the engine has the mod's to make it an advantage. The down-draught conversion is a waste of resources, as Paul well knows.
Just lookin' at the two setups it should be noticed the DGV manifold has a 90* KINK in it right from the point of entry. SU's go straight to the valves. Small enuff arms and you'd be able to tickle th' intakes from outside. /bcforum/images/%%GRAEMLIN_URL%%/smirk.gif
The illusion of "more power" with a DGV-ish thingie is simply because it has a squirter circuit, IMO.
EDIT: I'll do 'em (SU's) all day for $500 a set!!

aroostok,

IMHO, A properly adjusted pair of SUs are a joy to own. As was said earlier, set'um and forget'um...
I have had several As and Bs and have found the venerable SUs to be the easiest and cleanest choice. The Law of diminishing returns kicks in here... /bcforum/images/%%GRAEMLIN_URL%%/wink.gif

But... but all th' REALLY kewl guys say Webers is th' way t' go! I wanna have this car onna road so's I can show off at th' next gathering!
HELP!
...or words to that effect. /bcforum/images/%%GRAEMLIN_URL%%/smile.gif
DISCLAIMER:
This is in NO WAY a slam on anyone for wanting to go to a Weber conversion! That photo was as a complete farce for entertainment alone. The thing runs beastly strong with that DCOE and a Crane cam. Ported, matched, CC'd: the lot. I LOVE my side draught Webers.

DrEntropy,
You're such a kidder!! /bcforum/images/%%GRAEMLIN_URL%%/jester.gif
Now, aren't you slighting those of us who love the SU??? /bcforum/images/%%GRAEMLIN_URL%%/smirk.gif
Wait a minute, if I use the word LOVE when discussing a carb configuration ---
I need to get a life /bcforum/images/%%GRAEMLIN_URL%%/rolleyes.gif
