I just bought a Weber 48IDA, i need some help on the jets and venturies size. The engine is a rebuilt stock GSL-SE 13B 6-port.

Here is the recommend sizes from Racing Beat, I don't know if they are the right choices.

Venturi - 40mm
Fuel Jet - 195
Air Jet - 205
Emulsion Tube - F-4
Needle Valve - 250

Also, where is the cheapest place to buy these parts?

The cheapest price I found right now is this one... http://www.carburetion.com/Weber/weber.htm

 

racing beat is pretty accurate with their jetting information
here is a link to where we got our jets and what not

^^A+ service. Had a problem once and it was shipped overnight, free.

 

lazy... there was a big IDA thread just a month or 2 ago and you didn't even bother searching for it...

It's not the same engine, thanks for being smart, though.

 

Thanks for the link, but where are the price for the parts?

 

F-4 emulsion tubes? I guess the extra 2 ports like them but for what reason?

 

I can't seem to find 250mm needle valve for the IDA.... Where can I find them?

 

I got #3.00 metal needle from here...

Mazdatrix has the 3.3 glass ball...but I cant's stand those.

 

I'm running a 6port street port and I put plenty of jet info in that thread so it was the same engine. In my tuning I've found that there are very little changes between 13b's in tuning.

 

Does anyone know where i can get 2.50mm needle valve... I had been searching for days

 

Dude...call or order the #300 from racetep.....why would you want to go smaller if larger is available?

...the place is about 5 miles from my house....if you want, I'll pick one up for you and FedEx the ******!...sheesh.

 

I will just order it from racetap now
