Well im no expert but i want the most from my a14 that has twin su's. Is it worth spending the money to fit a pair of side draft webbers. I have been quoted approx $1000 for second hand carbies recoed and manifold + linkages.

Define the phrase "I want the most from my A14"
Most what? Driveability, economy, outright balls to the wall performance, allround flexibility, ..... what?

For balls to the wall performance, Webers combined with extensive engine mods, but overall driveability & economy will suffer.

For overall good performance, driveability, good economy & flexibility, you can't beat the original GX engines with their twin Hitachi's

Properly set up & tuned, twin SU's would be almost as good.

Ok its not gonna be a drag car i just want it to go resonably hard and also sound nice. I have nt got the car as yet not for another 2 weeks maybe i should wait till i drive it then see... I normaaly always want more.

Quote:For that, I recommend the factory Twin Hitachi carburetor setup.

DELLORTOES.... (not that I have compared the two)

I'd gladly take your $1000, pay a months mortgage, food for a fortnight, etc. AND fit your twin carbs. They'd be Dellortos though- better carb than a Weber- imho.

Why can't you do it yourself?

Fitting dual sidedraught carbs such as webers to an otherwise stock engine is a total waste of energy as the carbs will flow about twice as much air as the engine could possibly consume.
The net result is never really satisfactory.
The twin factory Hitachi's or a well set up SU install is going to be much more satisfactory for your needs.

Yeah, I totally agree with both ddgonzal, and Dodgeman.

You really have to decide what you want to do with it, if you want to have good power but on a budget then go the Hitachi's or SU's. But if you dont care on $$ then get the Dellortos, but like Doggeman said, you will have to open up the engine and do some $$ worth of work.

I got the twin 40mm sidedraught Dellortos on my ute, it goes really hard, lights up the rears no problem if you dump it at the lights and is just fantastic. BUT it has had about $15k spent on the engine by the previous owner...

Ok all sounds good i think this motor has forgies and has a jeff taylor head. So it probably will flow enough for the webbers but im still not sure whether to spend that extra money and just be happy the way it is.

Well if your not sure, put a little bit of money aside each week until you decide, that way you wont wast any on mods that you are going to change latter... I think that a lot of people wast so much money because they do a some mods then decide that it wasnt what they wanted. Decide exactly what your going for then do it...
