is it worth soucing a set of gx carbs for my a12 or should i just get a set of sidedraught webers etc.
what are the pros and cons of both, i have about 1000 to spend and i dont want something that i have to #OOPS# around with 6 months after i have had it tuned,
orrr
does anyone have another option that could be there for me
thanks, nathan

that oops says fcuk

Twin weber 40s have more power than GX carburetors (Twin Hitachi). With $1000 you can buy a nice used set and pay to have them tuned on a dyno. They look tough too. Just make sure to buy a set with appropriate venturi size.

If you have $1k to spend, If spent wisely, I would be tempted to go with efi. I'm sure it could be done. As much as I like carbies, efi can be leaps ahead, especially when it comes to efficiency.

yeah thats true but efi im guessing would need a mod plate?
and being on my p's i cant have anything modded so that my car will need a mod plate
thanks for your in put guys
what sorta money am i looking at for a new set of webers?
or is a quad bike carb/throttle the way to go?
im open to ideas thanks guys
oh and 1k is all i have now, i do have a job so i can save up more
but i dont want to spend more if i dont have too
and does anyone on the gold coast have any input about webers holding a tune in our climate?

for a street driver the gx carbies are far better, actually im much happier with gx carbs on my rally car over the webers i used to have

i say go gx especially if you dont wont the hassel of re-tuning, webers are shocking for that

efi for $1000 - no chance, not a system worth having

You could get a single throttle body EFI for $1000. Should be smoother than a carburetor, but the performance won't be nearly as good as with twin carburetors. And like 1200RC says, with Twin Hitachis you get power and smoothness.

sweet im liking the idea of the gx carbs,
what are they worth and how hard are they to find?
also, anyone heard of engine restamping?

Not sure why there is a misconception that Webers (and Dellortos) go out of tune. They are fixed jet and the only thing adjustable on them is the idle mixture and balance (when two or more carbs), and these only change if using a screw-driver).

Properly set up Webers/Dellortos, especially on a 'mild' engine, are very tractable and relatively economical (though unlikely to be as economical as "SU" type carbs.

That said, no carbs can ever be tuned perfectly across the rev and load range like EFI.

With a $1k budget I'd go Side-Drafts everytime. Gives plenty of scope for further tuning in future too.
