I wanna know who's done what kind of intake manifold and carb combo and what they think is better...

Thanx,

i love my rb intake with dellorto (modified 48 dhla) carb...what a difference

 

anyone else?

 

same setup, love it. (dellorto)

 

I liked my Weber, but I had nothing to compare it to other than stock. I didnt really have it long enough to get it tuned right though.

I recently installed a used Weber 45 on my stock 12A. I'm still in the tuning process but I certainly prefer it over stock. Years ago I had a 13B SP with a Mikuni set up (sidedraft too). It was ok but had tuning prob's with it ( i'm 99% positive it was lack of experience and no forum like this around to ask for help that caused that!)

 

Mikuni sidedraft all the way! I'm convinced these are the types of carbs rx7's were made to have. WAY more top-end power really brings out the rotary's potential.

 

gonna be getting a new carb and intake manifold soon......what is the best choice that would be able to handle a blow-through turbo set-up in the future??

 

Mikuni/delorto/weber but you are best with this type of manifold and a ITC dual barrel type of fuel injection set up. but the mikuni with larger valve with a med to large street port engine I liked best. with a stock engine the delorto.

 

does the delorto need any modifications to run a blow-through set up besides changing the jets, etc? because i heard that the side-draft dcoe webers do not

 

where could i find a mukini? they arent made anymore right? i know the weber has returned; maybe the mukini will follow???

 

You can get a turbo gasket set from cbperformance for the dellorto. Pretty simple to do actually.

 

Mine.

 

one that CRANKS AND WORKS!!!!!

 

and which dellorto would i use on a stock port 12a with a blow-through?? would i be able to use the racing beat 2 piece dellorto mani?

 

i like the dellorto with the lake cities 4" long manifold. straight shot at the intake ports, none of this U-bend stuff!

Also have dellorto on the REPU's 13b 4 port. 2 piece RB manifold and 41mm chokes. Really likes to rev. Normal day to day driving shift at 4500rpms though!

 

I have the Rotary Engineering setup with dual Weber 36DCD downdrafts. Runs like a champ when set up right, but I am starting to think it takes too much effort to keep it tuned. Dual carbs = BIG HEADACHES

My recent problem with my 80 was narrowed down to the carbs, as I stuck my nikki back on and am running without the power loss up high. Now if I could just figure out what I messed up on the Nikki to make the AP not get actuated. It shoots the gas when moved by hand, but only then...

 

I really like the 48 IDA set up. Excellent setup. Only down side is, for people who live in places where they see extremely cold temperatures. Many adjustment are very easy. This carb works great on anything from stock to PP engine, everything can be set up differently in just minutes. RB has them brandnew for 499 and an intake manifold is 250. You can find these set ups used for less.

I'm going to toss a vote to the 79 intake mani and Carling carb - just because I know that once I have that setup in my SP 12A, I'll be quite pleased

 

thanks a lot everyone
one last question.....are there any carb hats on the market for the dellortos or would i have to get one custom made?

 

i am really fat

 

High budget=Weber 48 IDA
Low budget=Modded Hitachi

 

do many of you guys have much experience with running dual carbs? i know they cna be a pain to tune but is it worth it?

 

there's a dual-weber manifold on ebay now...i think it's a two piece....looks decent
