I've been reading that a 48IDA is too large for a stock port 12a. Is this true? What are the thoughts on the size then for maximum power potential (streetibility is not a real concern, im building a C Street Prepared car). Would a 40 DHLA Dellorto be a good choice? Then comes the question of will the RB manifolds for said carbs worked with the smaller diameter carbs....

dell 48 if you can find one..then you would just have to jet it weber 45 dcoe..the weber 48 ida is big..but if you switch the chokes down then you will be fine...and manifolds can be found anywhere depending on what you get....upgrading your carb to a weber or dell is not going to be a cheap thing though..bc you have to upgrade your fuel system and other minor things..

its more or less a necessary to be competitive AND i dont have the nikki or manifold anyway

Dont be an internet parrot. Do you have any hands-on experience with any of these carbs???

Whizbang

is a 40 DHLA dellorto too small? or would that be about perfection?

too small.. i would never go smaller than a 45 on a stockport 12a.. max power will be seen with a 48..

okay then.

so if 48 is my target size, what manufacturer? Dellorto (if i can find one) or Weber? or maybe another? Its seems as though they are going to be somewhat close in price only the discontinued-ness of dellorto carbs makes me worried.

i do have hands on with my dell 48...havent put it on the car yet..but i am rejetting it...with webers..we all know that you are the god for that...

pinoyremix

for the dell..there is a member that is trying to sell his...the parts don't be to worried.they are not as accessible as webers..but parts you can buy some from cb performance..and they rest..you can order from dellorto.com...pretty good...but expensive..got some jets in 6 days...from england

so i can use the racing beat side draft manifolds under the "dellorto" components with a side draft weber. Supposedly a 48 DCOE exists, but all i ever see are 45s. Plus the 48 IDA is supposedly too large as well. So i think im going to go the route of the 45 DCOE with the racing beat upper and lower manifolds for the side draft and see how it goes on the stock 12a engine.

Ihave a 45 dcoe on a stock port 12a with an intake from mazdatrix it comes as a kit . I am using a RB street port exhaust. It runs fine. I ran it on a mustang dyno and pulled a 125 hp@ 5200 rpm and 102 ft. lbs. of torque.

Whizbang

how do you like the all around performance of it?

StumpDrummer

Id go with a small 4 barrel setup i think it was a rb intake i had ,matched the ports on the intake and a 600 eb carb, it will bog at low end but my god after 4k it was killer, id try a 500 or 390 4 brrl

holding the carb with 2 hands and admiring it is not the same as having "hands-on" in tuning.

pinoyremix

why do you have to pick on ppl just because they don't have the knowledge you do...just because i dont have all the experience you do..doesn't mean i havent learned anything...and i have done my research to some extent..

cause wacky is well.....just wacky

only reason i know my 48mm dhla is cause wakey sold me it. (and the headaches of making it run perfect). 48mm dell ftw.

TAKING ON MY PROJECT, EH BITCH?

Nice, but the new project is still going to be better than the last!

Whizbang

yea, i want to get a carb on her and get it up and going for some autocrossing.

i think with the efi setups, everyone is going bigger than 48, now most arent running a stock 12a, but ive everyones gone from 51mm to 62mm, i'd think a 48mm carb isnt too much on a stock 12a.

although i suppose if you're trying to auto-x the car, and make killer midrange, 45 might be better

just a thought

Damn...that's funny Mel.

48 IDA for the win, hands down! You can change choke size...jetting...to suit any port! Don't fck around, get one carb that can do it all...they are completely streetable, will cruise smoothly, and can get pretty decent mileage, depending on how far you nail it....I can get over 200 miles on a tank easily on a streetport 12A with a porperly tuned IDA..with more response and pull over any other carb....why do you think the best EFI setup on rotaries ends up with IDA style Throttle bodies? It just works.

Picking on anyone is not my intention. I just want people to back up what they post. this is to save others from headache and lost of $$$.

Perfect unmolested interior and rust free body = autox car? Pete would scold you! he uses the rusted of the rusted for his rallyx! Not due to choice, though.

Although it *will* last you for a long time.
