My carb has about just crapped out on me! I think after 23 years she needs to be retired. So I know what I am going to be getting for x-mas!!

I dont know what kinda carb I want? I have a 12a SP.

I want power!!!!! I can care less about MPG!

It needs to be some what easy to tune.

Also I have been thinking about getting a wide band tuner. So I can really get the most out of my new carb.

Give me your input.

It's just a sensor and meter. The sensor will need an 18mm bung welded onto your exhaust. Any muffler shop with a welder will have bungs, and they'll do it for $30 if you hand-carry the manifold in. It's just three wires to hookup, too. It couldn't be any more of a no-brainer.

I have a 51 IDA Weber, but would go for a Holley if on a budget. It has a problem with hard left turns (autocross-style) that you won't run into on the street, plus they're dirt cheap and easy to rebuild.

48 Ida

my wideband kit cost me 300.00 shipped. it's a PLX device and it's awesome as hell. it doesn't use the stupid circle gauge with the lights. it's straight up and very easy to see while driving.

it's completely worth it ifyou are seriously trying to tune. otherwise you are chasing your tail and a fuggin air/fuel meter is a damn joke. anyone that is seriously trying to tune their setup needs a wideband.

and crit does have a point, if on a budget the holleys are pretty sweet. very very easy to tear apart and rebuild and you can still get great power from them. good streetability.

If you want to go fancy for around town, find a Dellorto. Better progression circuit and it has a choke. Holleys are available with either a thermostatic or electronic choke.

I would say for street driving and power go with a mikuni, dellorto or WEBER!!. I have a sidedraft OER carb (a Japanese weber replacement) with an intake manifold that has long runners and wraps around the motor. Actually it is rotaryshack's setup. It is freaking awesome. Great driveability and GREAT POWER.

BTW it is a 45 great size the bigger ones arent so good on the street

Dellorto 48 or Mikuni, either way sidedrafts are the way to go!

Ok quit with all the junk and get a Weber 48 IDA, youll be glad you did.

rbf41182gt

where can you get dellorto's or mikuni's? Do they even sell them anymore?

I've been running a Sterling for about 2 months now and LOVE IT!!!

Problem with the Webers is they arent modified for our beloved Rx7's so one must know how to tune it correctly for optimum performance, and if your not running premix you will have to modify the carb to accept the OMP lines....However the RB modified Dellorto 48DHLA carbs are made for Rx7's with the OMP nipples attached and tuned to perform out of the box. Racing Beat no longer sells these beautiful Italian made carbs, but one can search Ebay as Dellorto's pop up from time to time. Sorry but a Weber cant touch a RB Dellorto 48 DHLA!!

REVHED

There's no such thing as "tuned to perform out of the box." Every engine has different requirements depending on things like porting and exhaust configuration. If you need a baseline setting for a Weber it's as simple as looking it up on the web. And they're made in Italy too last time I checked.

As far Weber's not being able to touch a Dellorto... there's a reason IDA's are the most popular carb for people who race rotary engines. It's because they perform the best.

Plus one carb that fits all....stock, SP, BP and PP

Amen! It's really the only carb the racers use. Even the Weber DCO doesen't cut it for racing. THe IDA is the only way to go. Now for a street car that won't see track use, the sidedraft works well and for that stock look the sterling would be a good choice.

Is that a fact? If it is, then I would like to line up with anyone near me with any non-48 IDA carbs.

I wonder why my other carbs (RB holley, RR&R mikuni, dellorto 48) has been sitting in the shelf collecting dust for many years, while the IDA's are nicely wrapped.

Ok. So far I have seen a lot of people saying webers. But a few with a sterling carb, and a couple for a holley.

Yes it is my dd, But I mostly do highway miles, back and forth from college. I walk to save gas around town!!!

I have read somewhere that a weber can be tough to tune. but with my new wideband will that make it easier?

I will also have to get a new intake mani right. I mean I want a new ported mani for my SP.
