can anyone give me an idea on some of the pros and cons of fitting a
48 mm weber

 

Pros- more power than stock carby
Cons- way more petrol than stock carby

 

ive herd that a weber only work efficently at full throttle is that right or are they ok for street use

 

They are ok for street use if jetted right. A second hand EFI setup is a much better way to go IMO

 

yeh but if was going to do that i would rob be tempted to go all out with the microtech computer system and other stuff but way out of my budget at the moment

 

cant see any cons its an rx-7... nope no cons... my car drinks about 25ltrs per 100kms but its not like I got the car for fuel economy. the upgrade carby is a good cheap way too go, with other mods like exhaust and intake and a good tune of course it will pull pretty decent make driving the car more fun, plus with the results it'll be worth the extra couple of dollars for fuel each week, even standard if its tuned right it will drive great

 

yeh thanx
im really consider it now cause i will make it a weekend driver and get a mild port should go great eventually

 

heya matey, just lookin through some of your old threads and saw you were asking about webbers, i got a rebuilt 12 ext. mild port with 48mm webbers tuned and runin by alex @ redline rotary. not dynod yet but guesstamating around 130kw. (beat 12a turbo by bout 3 car lengths other day, though was probbably **** driver) drove to bowral from city last night, got 268kms to 45 litres of feul. punched it a few times nothing serious. for around $500 to $700 its worth it for the power increase, im thinkin of going efi soon, you could have my webbers for $600.
