Outer Limits 4x4 Board

does anyone no what size jets to run in a 350 holley on a 3y hilux petrol as standard carby is useless

mate i dont think u can run a 350 on a luxy it will b way to big lol correct me if im wrong but i dont think it would work i thought of a weber carb cus they specialize in small carbies.i am interested tho cus i got 2 lux's with a 4y and a 3y and wanna change the carbies so yer i will let ya no if i get sum info.

cheers

i had a holley 350 on mine and left it standard just changed the float so i can use the sc14 supercharger on it and it worked good

I'm also interested in carb swap info for a 3Y..

Mine works fine, choke and all but wondering if a Weber or similar will get better economy or at least an extra horse or 2

I'm doing a full 7M-GE conversion but that won't happen till I have a shed in which to do it!

i have spoke to a couple of people and they say that a 180holley or 32/36 weber is the best option and it gives up to 30% power cain but you have to run extractors and sports exhuste i think thats the way to go

Yeah there's a guy selling reco 32/36 weber packs that bolt right on for $600 on ebay.. Reckons they're the ducks nuts.
Tempting but not sure about shelling 600 on a secondhand carb that i keep hearing iffy reports on, in a 4x4 context anyway.. (steep angle starving).
also hear they need regular tuning??

Any feedback from anyone running a weber much appreciated

Weber carbs are great. The 32/36 is a very good alternative. I cant say what they are like in a steep angle. But if they are set up properly in the first place you wont have to do any tuning in the future i.e Jet alterations. Providing the engine is in good condition with good manifold vacuum. They are standard on 2lt escost engines so finding one yourself shouldnt be too hard.

Any idea on fuel efficiency improvement?
The standard setup on the 3Y running 31" rubber only returns ~320km per ~55 litres of juice.. In my case anyway!
I'm also running a switched thermo so there's less parasitic loss on the motor to begin with!
