My 12a turbo project
So Im working on a 12a turbo project and my plans are doing it on the cheap. I mean like going to the junk yard or hitting up ebay cheap. DONT flame for such things. This thing is my project, not yours and I do what I wanna not what you wanna. ok. now that thats outta the way I do want some advice, but first the run down.
I got a S5 turbo and exhaust mani. Im going to elongate the bolt holes and make any other modifications to make it fit (from what ive ascertained all I need to do is elongate the bolt holes though.) Im getting a 48 ida weber and Im welding together my own carb hat (if it works out and theres a demand I may start producing these for others who want one) Then Im going to get the BOV and such things that I can from ebay.
Ok, now what I wanna know is what is a good place to start jet wise on the carb tuning. I dont mind going rich but I wanna avoid going lean. Anyone run a IDA with boost? The engine is staying stock ported. (port job is going on the 13btII thats going in another car) any info or advice or things to look out for on a boosted IDA is appreciated. Thanks

about how much boost can it handle? Im not looking for much boost, 10 psi tops but probably more likely around 7. guess after that its all just test and tune huh? no one else has tryed this carb with boost?

yeah, Im sure they would, but I have an ida and Im not going to spend more to get that carb. If a nikki can be boosted then I have no doubt an IDA can too.

hah. Good news Better news and bad news.
First the good, carb came today.
the better, Its a DCOE not and IDA, better for boost?
bad, is the carb made out of steel or aluminum or die cast? Im guessing aluminun as its so light for its size. Its got a crack that runs down one side where the venturi hold bolt goes in. I can weld it no problem but if its aluminum I might just JB weld it instead so I dont have a mess to clean on the inside of the bore.

Naa, Im going to stick with the JB weld. It will work fine, its just a little crack. webers are made from cast aluminium. That **** is hard enough to weld with out the years of gas getting absorbed into it as well, that stuff will burn way to fast and before I know it my little fixable crack will become a big hole.
So no one here knows about running boost through a DCOE? are you serious? wow. Oh well.

And I may be taking your posts slightly offensively, but if you want help then ask and dont get defensive. Some things you have to find out on your own, or search for it.

Sorry for the repetitive posting, but if you want to keep it cheap, then why buy another carb when the nikki will do just fine? Also, are you doing blowthrough or draw through? Have you given thought to fuel systems and ignition upgrades? You know that turbo cars run colder spark plugs, Need a rising rate fuel pressure regulator, and a better coil will help as well. Also, how are you going to get the fuel to return to the pump?
Edit: err, I mean tank lol.

DCOE's work great with boost. I would talk to www.rotaryshack.com. They have built many blowthrough setups and have a lot of experience.
Good luck.
And yeah, don't be so defensive, we aren't Rotary ****'s.

I didnt mean to come off too defensive. just a touch. any way, i got the whole carb and intake setup for 155. So it wasnt to much compaired for what even used ones go for. Im still not sold on welding the carb though. Id rather keep putting jb weld on it then mess it up welding it, especially since aluminum requires more heat then steel of the same thickness to get good penetration. It would burn through real fast. Maybe if it where thicker. Ive got the fuel thought of, Holley blue and a rising rate FPR. CHoke is already gone. I already have the s5 turbo stuff from another project that is actually changed up. The ignition is going to be direct fire via jeff20b's setup. DCOE's are deadhead carbs, fuel return shouldnt be an issue i dont think.
Now Im not saying I quite know everything Im doing here, but I do have the concepts down and access to all the equipment Ill need. I do imagine I will run into snags, but thats why places like this exist

No problem man, we are here to help one another. Again, I must strongly advise to get the carburetor welded or take it to a professional welder to have it fixed. Sure, JB weld is cheaper route, but if a pieve brakes off and gets "boosted" down your manifold, I bet that 100$ professional weld job would look tons better than a new engine.
