thanks I think i will also get a book. lates matt22

 

48 Ida

 

whats that mean? i really have no idea.

 

its the model of the carb , The brand name is webber , and 48 ida is one of the models theres a bunch more of webbers , you should search for webber carb direct ( i think thats the site ) Webber has sidedraft carbs , (which means the carb is sideways/ horizonal ) , downdraft wich i guess it sticks down , Dellororto is basically the same kind of , Just different brand name and THen Holley ,

 

i have a 600 holley , Holleys ok , Well at least i think so , but around where i live all the rotary guys that decide to go Carb , have holley , i see holley carbs usually on the Drag strip , so if your gonna drag race then i guess use holley , But all the AutoCross an Road race events that i go to an see rotary cars usually have Webbers OR dellorto's , sooooo i guess if your gonna drag then use holley , if your gonna road race go webber ,

 

weber is the jam

 

I run a Weber 51 IDA. That's a downdraft 2-barrel. The Dellorto DHLA is a sidedraft 2-barrel that has less power, better streetability and a choke. Then there's the Holley, Nikki and Hitachi 4-barrel normal-lookin carbs. There's also the occasional Mikuni sidedraft as well. A Dellorto DHLA 48 has a 48-mm main venturi. Holleys and such are measured in terms of cfm, Weber, Mikuni and Dellorto are typically described by throat size (40, 44, 48, 51 mm). Are you looking for pics, or what?

 

I have a Hitachi 4Bbl w/ Mechanical Secondaries.It seems to run good ....My only bitch is it doesn't have a Choke hooked up So I have to sit in the car w/ My foot on the gas til it idles usually about 7-10 Min.

 

pics are nice if they are handy, but no worries.

So if i was gonna use my car for daily driving and some autocross i should probably go with a Dellorto cause it would be more streetable. I would also spend more money on one thats easier to tune. I read that the webbers are easy to tune. how do you guys feel about that? Thanks for all your replys by the way. Matt22

 

You can find a link to my Dellorto setup for sale in my sig. Webers are more simple and make for generally better race carbs. Dellortos are more streetable because they have a longer progression region (part-throttle response) and a choke. Dellortos are unique in that you can even swap jets with the car running. You don't have to open the carb up to change jets. Webers have a larger selection of jets, but they're equal in terms of how easy it is to tune. Dellorto parts are harder to track down, as well, so getting a few spares is a good idea if you go with one.

ya , buy webbers or dellortos , Holleys to much of a problem ........Also when you pop your hood i would rather see some pretty Webber rather than a holley lol anyday .......

 

Very true. Webers, Dellortos and Mikunis just look like works of art. I always thought so too...

 

weber is all i sell!!

 

so Crit what do you need for your RX2, that you would consider partial trade, for your old setup. even though i wold have to buy the 12a intake pieces but still evenutually might go to the 13b. let me kwow. matt22

 

i got a weber ida 48 on my 87 rx7, and i love it, runs great

 

holley 600cfm setup from rb on my sp 13b.

 

Im going P-Port in my RX-3. I will be trying out a GENE BERG 55 IDA style carb. I wanna see if this will work better than my old 51.
